Pour répondre à votre question , selon eux l'été va être beau et dans les températures de saison de la mi-juin au mi-septembre environ . Pas de grosse canicules ni de temps pluvieux. Ca va etre sec et ensoleillé en général. Et ca commence à la mi juin ! Pas avant

The rain is needed for our plants and trees etc. I love cooler temperatures and wish it would be 15-20 degrees the whole summer!!

Maple syrup season

Hi, what is your prediction for the start of maple syrup season 2019? Last 2 years the first drops were mid February, seems unlikely this month! Thanks.

Montreal summer of 2019

I was wondering and hoping it would be a much cooler summer this year.
Hopefully we will have 'lower than normal' temperatures...
I love winter!!

Bring on the heat.

The forecast from Environment Canada is going to be the hottest summer on record.
Hope they are right, so I can enjoy my boat, deluxe camping and our seadoos.
We hate cold or cool weather. To all you sun worshipers, have a great HOT summer.
