More record-breaking heat is on the way to Montreal.

The weather networks are forecasting a five-day heat wave for Montreal, beginning Friday and lasting through Tuesday. 

And we haven't even talked about the city's air quality.

There’s no time like the present to bookmark Montreal’s air-conditioned public places, swimming pools, local beaches and shaded green space.

A sweltering and humid air mass is expected to drive daytime highs between 30 °C and 34 °C, with humidex values approaching 40. 

Overnight temperatures will remain warm, with lows between 21 °C and 24 °C.

What was the hottest summer in Montreal?

What is the hottest it's ever been in Montreal? The warmest day ever in Montreal occurred during the historic heatwave of 1975, with a temperature of 37.6C (99.6F) on August 1, 1975.

Environment Canada urges Canadians to take precautions during extreme heat. 

This includes identifying whether you or those around you may be more vulnerable to heat-related illness, and checking in regularly—several times a day—on older adults, people living alone, and others at greater risk.

Be alert for early symptoms of heat exhaustion in yourself and others. 

These can include headaches, dizziness, nausea, extreme tiredness, dark-coloured urine, and intense thirst. 

If symptoms appear, stop all activity and start hydrating. Drink water frequently, even before you feel thirsty, to stay ahead of dehydration. Keep your living space cool by closing blinds, opening windows if it’s cooler outside, using fans or air conditioning, or relocating to a cooler area. 

If your home stays hot, consider going to an air-conditioned public place like a cooling centre, library, community centre, or shaded green space.
