I read an article last month about how 2019-23 is going to be the hottest years we’ve had in years. Then I read how it’s going to be cooler in 2019?lmao. You guys better start making sense. Because you even said that this summer was gonna be cooler than normal and here we are living in pure heat (which I enjoy). So if anyone has anything to add to this. Feel free.

I was just looking for

I was just looking for previous predictions about this past summer because it was one of the nicest in recent memory. I read that they were predicting a cool and wet summer for 2019 and got bummed out. But now I can see that it's potentially fake news.


Personally I wouldn’t give up the seasons in Canada for any other place in the world. Living here is like spinning a roulette wheel, you never know what you are going to get and each day is a surprise. Weather is unpredictable, after all Mother Nature takes care of it and she will deal out whatever her mood dictates. So sit back fellow Canadians and find some positive in the weather, being so negative must be exhausting. If you don’t trust what the Almanac predicts why are you following it?

Weather in Canada

I totally agree with you, the weather is so different each day.

Will this summer be a repeat of 1992?

I was just wondering if this summer will be a repeat of 1992 because I heard that 2019 will be a grand solar minimum. Solar minimums cool the entire globe.


are people really fighting in the comments of the the old farmer's almanac website? for real, y'all? relax.


Why?? are you stating the weather for S.Ontario the same for N.Ontario???...Our weather is completely different then that of S.Ont,..

Weather opinions

Travel the world a little folks. Water is like gold in some parts with that goes food. Stop your bitching. Do like in the old days..." dip your finger in the well, shove it out the door see from which direction the wind is coming from" even sailors do this one. Think as to which direction warm,cold, wet or dry comes from per season and then dress up or dress down accordingly.


Why are we lumped in with Souther Ontario when we live in Northern Ontario.....not the same at all!
