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

Really ? How very nice.

First time on this site and I thought I would read the comments . Wow . I can't believe how insulting people are to other people.

Truth be told , no one , yes I said no one , can predict the weather . It is the only job out there where the predictions can be wrong 98 % of the time and those predicting it still keep their jobs. In any other profession ,if that many mistakes were made, they would be fired long ago.

The best solution is to step out your door. If it is windy and cool put on a jacket , if it is stinky hot and humid , shorts and tee shirt works, if it snowing , sleeting , freezing rain .....dress accordingly and drive accordingly.

Oh, and stay away from nasty people . They deserve to spend their time with themselves. .

Weather is weather

Let's see simmer is hot winter is cold lol
Enough said

It's just weather

Why are people arguing in a weather forum? I wouldn't live anywhere else! Enjoying all 4 seasons, and the unpredictability of our weather makes me appreciate every day.

Could the almanac be more specific.....I would like to know about the weather for the Timmins area this coming summer and not lump us in with Sudbury which is 5 hrs away and weather forecasts could be totally different!

So far in my area all predictions have been 100% accurate. To everyone else, get over it, if you dont like your weather, move somwhere that will help you whine, complain and b*tch less. Have a great summer, happy planting everybody

Hot weather

On May 1-2, the temperature was 28 degrees Celsius in Etobicoke. Maybe May will be ABOVE average. They said May 1 mild. 28 degrees isn’t mild. It’s hot. At least it’s better to not have to wear winter coats.

Be Postive

Enjoy any weather we get . Can't control it ,hot ,cold, warm make the best of it . Remember Wynne says the carbon tax we pay help climate control. No that's smog at its best.Enjoy the weather .no tax can help it.lol

Smog?

Dave, have you already forgotten all the real smog advisories of a few years ago? That's why we closed the coal fired plants. I hate higher gas prices as much as the next guy but the best way to move past dangerous fossil fuels is to make them more expensive than alternatives.
Enjoy the summer whatever may come!
