If you’re spending the Thanksgiving Weekend in Ontario, you’re in for a treat as the fall colours are now peaking across much of the province! From Central Ontario to the Niagara Escarpment and parts of Southwestern Ontario, this weekend will showcase some of the best fall scenery of the season.

Over the past week, colour change has surged in many areas across Central, Eastern, and Southwestern Ontario, bringing that classic explosion of red, orange, and gold to the forests. For many regions, this weekend marks the perfect time to take a drive, hike, or just relax outdoors surrounded by nature’s best display.

Parks like Forks of the Credit, MacGregor Point, Sauble Falls, The Massasauga, Frontenac, and Murphys Point are all sitting at or near peak colour levels, with coverage between 70 and 90 percent. These areas are glowing with rich maple tones, offering stunning backdrops for family gatherings and Thanksgiving photos.

FALL COLOUR PARK TRACKER

However, farther north, the colours are starting to fade. Northern sections of Central Ontario, including Algonquin, Arrowhead, and Bonnechere has reached their peak several weeks ago, and the recent rain on Friday has accelerated leaf drop in those regions.

In fact, Mikisew Provincial Park has become the first location to officially move out of peak season, with around 80 percent leaf fall now reported. Many of these northern parks are still worth visiting, but visitors can expect more bare branches mixed with patches of remaining colour.

The transition southward is now well underway, with vibrant hues starting to spread into the Golden Horseshoe and Lake Erie shoreline regions. Bronte Creek, Turkey Point, and Point Farms are now showing brilliant orange and yellow tones, while Rondeau and Wheatley continue to progress slowly, likely about one to two weeks away from their peak.

For those in the GTA, Niagara, and Prince Edward County, this weekend should deliver plenty of colour and comfortable weather for outdoor plans.

THANKSGIVING WEEKEND WEATHER FORECAST

The good news is that the Thanksgiving Weekend forecast looks mostly favourable for outdoor activities; however, there will be a few areas of rain to work around.

ESTIMATED TOTAL RAINFALL ON SATURDAY - MAP FROM WEATHERBELL

Saturday will start off on a cloudy and damp note for many, especially across Central Ontario and portions of the GTA. Some scattered precipitation is expected during the morning and early afternoon hours, with the chance for locally heavier pockets of rain near the northern shores of Lake Ontario, between Toronto and Cobourg. Rainfall amounts could reach 10 to 15 mm in those localized zones.

Don’t let that discourage your plans, though, as the rain will be scattered and not persistent, and most areas should begin to dry out later in the day. By Saturday afternoon and evening, conditions will improve across Southern Ontario, while some lingering showers may persist just north of Lake Ontario.

Sunday looks to be the best day of the long weekend. Forecast models show mostly dry and mild weather, perfect for any outdoor Thanksgiving plans or fall colour tours. A few isolated showers could develop in Niagara or Far Eastern Ontario, but these should be brief and light.

ESTIMATED AIR TEMPERATURE on SATURDAY - MAP FROM WEATHERBELL

After a cool and damp Friday, temperatures on Saturday will hover right around seasonal values, with daytime highs in the low to mid-teens. Which is about what you’d expect for early to mid-October. It’ll feel crisp, but not unpleasant, especially once the rain clears.

ESTIMATED AIR TEMPERATURE on sunday - MAP FROM WEATHERBELL

On Sunday, slightly warmer air returns. Temperatures will rise into the upper teens, with some areas possibly touching 20°C or a bit higher in parts of Southwestern Ontario. It’ll be a comfortable, mild day overall, great for hiking, apple picking, or those traditional family dinners outside if you’re lucky enough to have a sunny patio.

Monday, Thanksgiving Day itself, should feature similar conditions to Sunday with a mix of sun and clouds, and daytime highs again in the upper teens or low twenties.

FINAL THOUGHTS

This Thanksgiving Weekend will likely offer one of the most colourful backdrops in recent memory across much of Southern Ontario. With so many regions now at or near their fall colour peak, and comfortable weather expected through much of the weekend, it’s the perfect time to get outdoors and soak in the season.

If you’re heading north, expect a more subdued scene with leaves already past peak. But if you’re staying closer to home in the GTA, Niagara, or Southwestern Ontario, you’re right on time to experience the full brilliance of Ontario’s fall foliage.

Grab your camera, take a drive down a country road, or plan a hike through one of Ontario’s provincial parks. The combination of crisp air, golden forests, and warm afternoon sun makes this Thanksgiving one to remember.

Enjoy the beauty, and Happy Thanksgiving from all of us at Instant Weather!

Fall Colours Reaching Their Peak Just in Time for Thanksgiving Weekend for Much of Southern Ontario

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

It’s shaping up to be a picture-perfect Thanksgiving Weekend across Ontario, and nature is putting on one last spectacular show before winter sets in. Across much of the province, the fall colours are now reaching their peak, just in time for the long weekend and this year’s display is one you won’t want to miss.

If you’ve been waiting for the ideal time to hit the road for a scenic fall drive, this is it. Central and Eastern Ontario are bursting with colour right now, with brilliant reds, oranges and yellows covering the forests from Muskoka to the Ottawa Valley.

FALL COLOUR PARK TRACKER

Parks such as Algonquin, Arrowhead, Bonnechere, The Massasauga, Silent Lake, and Bon Echo are all reporting colour change at or above 70 percent. The rich mix of maples and birches is producing a stunning contrast that paints the landscape with fiery autumn tones. For many areas, this is the absolute peak which is that magical window when most trees are fully changed but still hold plenty of leaves.

However, that window is short-lived. Some parks are now reporting more than 50 percent leaf fall, meaning these vibrant views won’t last much longer. If you’re planning a trip to Algonquin or other northern parks, this weekend could be your last chance to experience the full canopy before winds and cooler nights strip the trees bare.

Even with the ongoing leaf fall, the colour coverage across Central and Eastern Ontario remains exceptional. Parks including Frontenac, Voyageur, and Mikisew are glowing with late-season golds and deep reds, offering some of the best hiking conditions of the year. Clear skies and mild temperatures will make it easy to spend the whole day exploring the great outdoors.

While the north is beginning its gradual slide past peak, Southern Ontario is just getting started. From the Niagara Escarpment to the Lake Huron shoreline, and stretching east through Prince Edward County and the GTA, colour change is advancing quickly. Many of these regions are now sitting between 40 and 60 percent colour change, which means peak fall colour conditions are expected to line up perfectly with Thanksgiving Weekend.

That’s welcome news for anyone planning outdoor gatherings or day trips over the long weekend. Whether it’s a drive through the Dundas Valley, a picnic at Forks of the Credit, or a stroll through Rondeau or Bronte Creek, the next few days should feature stunning scenery and warm sunshine.

The latest high-resolution model data even suggests we’re in for another burst of summer-like warmth across Southern Ontario. On Sunday, temperatures are forecast to climb into the mid to upper twenties, with some inland areas possibly reaching the 30°C mark.

It’s a rare treat for early October and more like something out of August than Thanksgiving Weekend. For those closer to the lakeshores, expect slightly cooler highs in the lower twenties thanks to the lake breeze. Still, it’ll be a gorgeous day for a fall road trip, with plenty of sunshine and mild winds making for ideal driving conditions.

The warm weather will also help extend the life of the remaining leaves, giving the region a few extra days of brilliant colour before cooler air and rain return later next week. So if you’ve been putting off that annual fall colour tour, now’s your moment.

For the best viewing experience this weekend, head toward higher elevations in Central and Eastern Ontario, where the mix of tree species and cooler nights has created the most vibrant hues. Algonquin Provincial Park remains the top spot for photographers and nature lovers alike, with Arrowhead, Bonnechere, and Silent Lake close behind.

Those staying closer to home in Southern Ontario will still be rewarded with spectacular views. The rolling hills around Caledon, Mono Cliffs, and Hockley Valley are quickly transforming into a patchwork of gold and crimson. In Niagara, the escarpment trails and vineyards are beginning to glow, creating a perfect backdrop for Thanksgiving festivities.

Don’t forget about Prince Edward County, where fall colours are blending beautifully with the region’s scenic farmland and wineries. Areas like Sandbanks and Presqu’ile are starting to see that golden shift as maples and oaks catch up to their northern cousins.

As always, timing is everything when it comes to fall colour chasing. While many areas will look their best this weekend, winds or rain later in the week could quickly thin out the foliage. Keep an eye on local forecasts if you’re planning to travel, and be ready to head out early in the morning for the best light and least crowded parks.

So charge up your camera, roll down the windows, and take in every view, because before long, those vibrant trees will trade their fiery tones for the bare branches of late fall. Enjoy the show while it lasts, and have a wonderful Thanksgiving Weekend surrounded by the best of Ontario’s autumn beauty.

After a Slow Start, Fall Colours Now Entering Peak Across Southern Ontario

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

An unusually warm start to autumn across Southern Ontario has delayed the typical fall colour transformation, leaving many waiting longer than usual for those vibrant displays. In our last update from early October, peak colours had only been reached in Central Ontario and parts of Eastern Ontario, several weeks later than usual.

However, the colder weather that settled in over the past few weeks has helped speed up the transformation across the region. As we head into the weekend, most areas in Southern Ontario are now approaching or experiencing peak colour change.



For provincial parks that reached their peak earlier this month—such as Algonquin Park, Arrowhead, and Bonnechere—the best days have likely passed, with reports indicating that fewer than 40% of the leaves remain on the trees.

Note: The above map is extrapolated using data from OntarioParks.ca, but some parks may not have updated their latest report yet. As such, the actual colour change in your area may be further along than currently reported.

Keep in mind that many parks have closed for the season after Thanksgiving, which explains why some areas lack data in our latest updated map.

Currently, the following parks are experiencing peak fall colours:

  • Arrowhead: 100% colour change | 40% leaf fall

  • Balsam Lake: 60% colour change | 30% leaf fall

  • Batchawana Bay: 90% colour change | 40% leaf fall

  • Bon Echo: 80% colour change | 50% leaf fall

  • Bronte Creek: 50% colour change | 20% leaf fall

  • French River: 80% colour change | 50% leaf fall

  • Killarney: 80% colour change | 40% leaf fall

  • Killbear: 60% colour change | 30% leaf fall

  • MacGregor Point: 60% colour change | 40% leaf fall

  • Mark S. Burnham: 50% colour change | 40% leaf fall

  • Mono Cliffs: 60% colour change | 20% leaf fall

  • Oxtongue River-Ragged Falls: 100% colour change | 40% leaf fall

  • Sauble Falls: 100% colour change | 40% leaf fall

  • The Massasauga: 90% colour change | 20% leaf fall



The last regions still waiting to reach peak colours are in Deep Southwestern Ontario, along the Lake Erie shoreline, and in parts of the Golden Horseshoe. Parks in these areas, including Pinery, Wheatley, Rondeau, Turkey Point, Darlington, Presqu'ile, and Sandbanks, are reporting between 30-40% colour change. It's likely that these parks will reach peak colours by next weekend.

Remember that peak fall colours typically last for about a week or two, but this can vary based on weather conditions. The peak period ends once more than 50% of the leaves have fallen, which can happen quickly after a strong windstorm. So, make the most of the season and get out there while the colours are at their brightest!

Fall Colours Reach Peak in Parts of Southern Ontario Heading Into First Weekend of October

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

Fall colours have been slow to arrive in parts of Southern Ontario due to a relatively mild September, but as we move into the first weekend of October, the transformation is starting to take hold. Several parks are now within their 'peak' fall colours range, providing excellent viewing opportunities.

The best spots to see the vibrant colours this weekend will be in Central and Eastern Ontario, as well as Bruce County along the Lake Huron shoreline. Many parks in these areas are showing between 40-50% colour change, with some even nearing full transformation!



Note: The above map is extrapolated using data from OntarioParks.ca, but some parks may not have updated their latest report yet. As such, the actual colour change in your area may be further along than currently reported.

All provincial parks in Southern Ontario are reporting at least 10% colour change, indicating that the seasonal shift is well underway. However, it could take another week or two for many areas to reach their 'peak.'

With Thanksgiving just around the corner, it’s likely that much of Southern Ontario will be hitting its peak fall colours, making it the perfect time to enjoy the beauty of the season during the long weekend.

For those wondering, 'peak' fall colours occur when at least 60% of the leaves have changed. Based on this, Algonquin and Mikisew Parks are officially in their peak, though this won’t last long. Mikisew is already reporting 70% of its leaves have fallen, so Algonquin might be a better option for now, with only 20% leaf fall reported.



Several provincial parks are currently showing between 40-50% colour change, mostly in Central and Eastern Ontario:

  • Arrowhead (50%)

  • Charleston Lake (50%)

  • Frontenac (50%)

  • MacGregor Point (50%)

  • Sturgeon Bay (40%)

  • Darlington (40%)

  • Turkey Point (40%)

  • Murphys Point (40%)

  • Bon Echo (40%)

  • Silent Lake (40%)

  • Driftwood (40%)

These parks are offering good chances to catch the fall display, and since the data can be a few days old, they may already be approaching peak colours by the weekend.



The remaining parks in Southern Ontario are reporting 20-30% colour change, especially around Lake Ontario and Southwestern Ontario near Lake Huron.

Parks like Pinery, Awenda, Presqu’ile, Forks of the Credit, and Port Burwell are still at about 10%, but with cooler fall weather settling in, this will likely change quickly in the coming days. The peak for these parks is expected to arrive in 10-15 days, just in time for Thanksgiving weekend or shortly after.

Stay tuned for more updates as we continue to track the progress of fall colours across Southern Ontario!

First Day of Autumn Arrives as Central and Eastern Ontario Approaches Peak Fall Colours

NOTE: YOU CAN CLICK ON THE MAP TO OPEN A ZOOMABLE IMAGE

As we entered September, it seemed like Mother Nature was eager to shift from summer to fall, with temperatures dropping to near freezing and even some northern areas witnessing the first snowflakes of the season.

But since then, the weather has taken a complete 180. Over the past few weeks, Southern Ontario has experienced a consistent pattern of above-seasonal temperatures and minimal precipitation. This unusual warmth for this time of year has slowed down the transition to fall colours across the region.

With the Autumn Equinox taking place early Sunday morning, we are officially in autumn, both meteorologically and astronomically. As we move deeper into the season, we’re starting to see some notable shifts in fall foliage, especially in Central and Eastern Ontario, according to the latest data.



If you're looking to catch the fall colours this week, your best bet is to head to higher elevations in Central and Eastern Ontario. Provincial parks such as Mikisew, Algonquin, and Bon Echo are reporting that around 40% of the leaves have started their transformation. The higher elevations experience slightly cooler overnight temperatures, which accelerates the colour change compared to other areas.

Note: The above map is extrapolated using data from OntarioParks.ca, but some parks may not have updated their latest report yet. As such, the actual colour change in your area may be further along than currently reported.

The ‘peak’ fall colours occur when at least 60% of the leaves have changed. With these parks now at 40%, we’re likely just a week or two away from peak viewing, perhaps as early as next weekend.

We’re also seeing some colour change along the Bruce Peninsula and throughout many parks in Central and Eastern Ontario, where about 30% of leaves have started changing. This includes parks like Sauble Falls, Arrowhead, Sturgeon Bay, Silent Lake, Frontenac, and Murphys Point.



For the rest of Southern Ontario, there is some minor colour change being reported, with 10-20% of leaves beginning to turn. However, peak colours are still several weeks away in these areas.

An important note: The calm weather over the past few weeks has allowed trees to hold onto most of their leaves. Without any significant wind events, the leaf fall percentage is averaging around 10-20%. If these calm conditions continue, we should see a vibrant display of colours in the weeks ahead.

Looking at the medium to long range forecast, we’re expecting slightly above-seasonal temperatures to continue through the rest of September. This could mean peak fall colours might arrive later than usual this year, although it’s hard to say for certain. We do anticipate more active weather this week, with several rounds of heavy rain possible, which could potentially knock some leaves off the trees.
