Cold Weather IN THE SUMERTIME?!!

On September 9, 2018, it was a high of 13 degrees in Etobicoke. It's still summer that day. I don't understand. I've been told that I couldn't wear just a T-shirt in February because it's not summer. But it currently IS summer and people are still telling me to wear jackets. That doesn't make any sense. Wearing a jacket should depend on what SEASON it is. I am sooo mad!


Weather depends a lot on which direction the prevailing winds are coming from. When we get warm days in the winter, (like in February 2017), the winds are frequently coming from the south, bringing warm air from the Gulf of Mexico. When we get cold days, the wind is frequently coming from Hudson's Bay or the Northwest Territories. I hope that this provides some explanation.

Canada eh

Dress how you like everyone is different, pay no mind to peoples comments and go with the flow, after all we live in Canada and our weather is unpredictable, i love our country and the weather it throws at us


I agree with everyone who comments how lucky we are to live in Canada and enjoy 4 distinct seasons. How boring and uncomfortable it would be to me to live some place where it is always warm or blistering hot and humid all year around.

Cold Weather in the Summertime

Perhaps a thermometer would help - I have coats for each temperature range as I walk my dog 4 times a day - ignore the seasons and watch the thermometer -


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.


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?

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.
