With June finally upon us, it's time to embrace the arrival of summer and eagerly anticipate the adventures and experiences it holds.

As we head into the summer of 2024, The Weather Network, Canada's trusted source for weather information, has unveiled its highly anticipated 2024 weather forecast for June, July, and August. 

This year, a season of warmer-than-normal temperatures, fewer rainy days, and abundant sunshine for most of Canada is expected. While this might sound perfect for lakeside lounging, the forecast comes with some caveats.

National Overview

Canada can expect a warmer summer overall, with temperatures soaring particularly in July and August. Rainfall will be near or below normal, leading to potential droughts, heightened wildfire risks, and poor air quality.

Western Canada will experience a typical summer with hot periods, but the heat won't be as intense as in recent years. More scattered showers and thunderstorms are expected, which could help mitigate wildfire risks somewhat.

Central Prairies to Atlantic Canada will see warmer-than-normal temperatures, especially in July and August. June will offer some cooler reprieves, but extended heat waves are a significant risk.

The La Niña Twist

After a winter dominated by El Niño, we're transitioning back to La Niña, characterized by cooler Pacific Ocean temperatures. Historically, such transitions have brought cooler, wetter summers to western Canada. However, this La Niña event is developing uniquely, so past patterns may not fully predict this summer's weather.

Final Thoughts

While many Canadians may look forward to a sunnier, warmer summer, it's essential to stay vigilant about the associated risks like droughts, wildfires, and severe storms. Keep an eye on weather updates and stay prepared for the changing conditions this season.
