I always find it ironic that just when the temperature starts to heat up towards the scorcher mark we hit the longest day of the year – then it’s downhill from then til just before Christmas.

Today is the Summer Solstice (7:09 p.m. tonight actually), first official day of Summer, when the tilting angle of the Earth brings the flight path of sunlight furthest north. And according to Environment Canada this is going to be day 2 of the heat and humidity wave:

“Temperatures are expected to reach the low to mid thirties today With humidex values exceeding 40 for all of Southern Ontario and the National Capital Region. The hot and humid conditions are expected to continue through Thursday.

Furthermore, night-time temperatures will also remain very warm and are not expected to drop below 22 degrees in most areas.

This will make for very uncomfortable conditions. It is advised to stay in an air conditioned place or seek shade when possible, drink Plenty of water and limit physical outdoor activity.

The heat and humidity are expected to break by Friday with the passage of a cold front.”

Taking in plenty of (non-alcoholic) fluids is a good idea for the next couple of days, as well as shutting curtains on the hot side of your house and opening windows / running fans in the evening and overnight. And keep an eye on your neighbours and pets – especially seniors! And as for that lawn mowing you might want to hold off until the weekend.

But it could be worse for this longest day of the year! Thunder Bay is expecting up to 100 mm of rain today and there are flood watches out in many locations in British Columbia.

But if the heat is too much for you just remember… it’s all downhill from here…
