Splash pads open for heat wave Montreal’s splash pads are opening to keep people cool as the heat wave and COVID-19 create a tough balance.

Montreal — We’re not out of it yet, Quebec.

Through the week, high temperatures will return as another sticky mass of hot air sweeps the province, pushing humidex levels towards a perceived 40 degrees in some areas.

A special weather advisory is in place for the following areas:

“Temperatures will approach 30 degrees Celsius and humidex values could reach 40 on the hottest days, Friday and Saturday,” reads the advisory from Environment Canada.

“In addition, the nights will be uncomfortable, with lows near 20 degrees Celsius from Wednesday through Monday.”

Young children, pregnant women, the elderly, persons with chronic underlying medical conditions and those working or exercising outdoors are at elevated risks of heat stroke and exhaustion.

“Drink lots of water, even before feeling thirsty, and keep cool,” reads the weather advisory.
