How the Almanac predicts weather

The Editors's picture

Hi, Aryanna, The weather temperature you reference is an average for the entire month. The Almanac weather isn’t meant to be viewed on a daily basis. Long-range weather is calculated over a year in advance, with predictions versus historical averages so you get a sense of what is typical (colder or warmer than average). Here is more information about how the Almanac predicts: https://www.almanac.com/content/how-old-farmers-almanac-predicts-weather For daily weather, we’d direct you to our short-range weather forecasts. We hope this is helpful.

Long range weather forecast

I was delighted to see the long range weather forecast on your page until I realised that it is for
Southern Ontario only. I do not live in Southern Ontario. I live in Thunder Bay, Northwestern Ontario. It is
1399 km from Toronto, Ontario or a 14 hr. 52 minute drive and 1006.8 km from Sudbury or a 10 hour and 53 minutes drive.
Would you please send me the long range weather forecast for January and, if possible, February for my area.
Thank you for your assistance in this regard.

Thunder Bay

Hi, Janet,  Thunder Bay is easily within our coverage area. This free Web site is a companion to The Old Farmer’s Almanac publication. Every month, we post the current month’s and next month’s long-range prediction, courtesy of The Old Farmer’s Almanac. You can find all 12 months in the Almanac itself: https://www.almanac.com/wheretobuy

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...
