Hot, humid weather expected today into Tuesday: Environment Canada – BarrieToday




Special weather statement in effect for:

  • Barrie – Collingwood – Hillsdale

First heat event of the season.

Hot and increasingly humid weather is expected today into Tuesday.

Temperatures will approach 30 today in many areas. Temperatures tonight are forecast to briefly dip into the upper teens.

However, maximum temperatures on Tuesday will be in the low thirties, and with forecast minimum temperatures in the low twenties in many areas, little relief from the heat is expected on Tuesday night.

Cooler air is expected to arrive on Wednesday.

These conditions pose a health risk when you are not used to the heat.

Everyone is at risk from heat, especially older adults; infants and young children; and people with chronic illnesses.

You are advised to 1) drink plenty of cool liquids before feeling thirsty; and 2) keep cool by dressing for the weather and spending more time in a cool place.

Please continue to monitor alerts and forecasts issued by Environment Canada. To report severe weather, send an email to or tweet reports using #ONStorm.
