Montreal weather will sizzle this week with a possible heat wave that ends in a downpour

Montreal is about to sweat buckets with its first scorcher of the year. Environment Canada is warning residents that the next few days may feel like living in a sauna.

The mercury this week is set to skyrocket past the 30-degree mark for at least three days straight.

On Monday, the forecast hits a high of 31 C, feeling more like 33 C thanks to the humidex. Overnight, temperatures will drop to a cooler 17 C, but don’t expect any real relief. Tuesday cranks it up to 32 C with a humidex of 34 C.

Wednesday is expected to keep the sizzle going at 32 C, and Thursday might throw in some clouds and a 60% chance of showers to tease you with false hope, but it’s still hitting 29 C. Friday finally offers a break with rain and a high of 20 C.

Météomédia confirms it could be Montreal’s first heat wave of 2024 if we get at least three consecutive days above 30 C. Since 2005, Montreal usually gets about four heat waves a year and they usually occur around the end of May and start of June. So, summer is just getting warmed up.

Heat waves are no joke. Environment Canada advises watching out for heat exhaustion signs like heavy sweating, muscle cramps, dizziness, and nausea. Heat stroke is even worse — no sweating, but very hot, red skin. High risk groups include older adults, infants, people with chronic illnesses, and anyone working outside in the heat.

"Never leave children or pets alone in a parked vehicle," the agency warns.

You can stay cool by hydrating with water, wearing light clothing, and finding air-conditioned places to hang out. If you have vulnerable neighbours, friends, or family members, you should check up on them regularly.

The good news is the heat won't last forever. By the weekend, temperatures drop back to the low 20s with more rain. So, enjoy the sun while you can.
