weather
So far the forecast for November is spot on where I am..not far from Huntsville ont..so in the area..so far so good..read your forecast for years..pretty accurate if you ask me...Thanks Farmers Almanac
More local forecasts
I really like these forecasts, but I do wish the regions were more localized. The weather can be very different in Windsor vs Toronto or Elliott Lake! Thank you.
Weather so far
Where I live (above the snow belt) the almanac has been spot on.
Good job
Weather
Sudbury is not located in southern ON and the forecast is not accurate. We are having our first major snow storm and there is no indication of this on your prediction.
Englehart too !
I agree with you, very inaccurate information here. We have over 3" so far today.
sudbury
sudbury sure is southern ontario! Mid at best...
Big Thanks
I would like to thank you for your long term weather forecasts. I look forward to them all the time, and I am so glad that you are 90% accurate. It gives me time to prepare for the bad weather in lower Ontario.
Thanks again, and have a good one.
Thunder Bay
Thunder Bay is not Southern Ontario, it's North Western Ontario, the weather is completely different there. This won't be accurate for anyone past North Bay.
Long Range weather - Canadian Thanksgiving
Hello!.. I have been seeing others' requests for long-range weather forecasts and wondered if it would also be possible to find out more for the Orangeville area over the Canadian Thanksgiving weekend? - October 11-14, 2019. Thank you so much!
Summer 2019
Summer 2019 definitely hasn't been cool and rainy as predicted for Southwestern Ontario. It's been very hot and humid with drought conditions, which can always be expected for that area.
