As domestic travel heats up, so does the predicted forecast. 

After a sluggish spring, meteorologists say much of Canada will jump straight into a hot and sunny summer.

The Weather Network (TWN) predicts warmer-than-normal temperatures across most of the country—great news for travellers planning beach days.  

“This summer will really come through for those who have been longing for warmer weather,” said Doug Gillham, Senior Meteorologist with TWN. 

“However, this summer will also illustrate the fact that too much hot weather brings many risks.”

Eastern Extremes

In Ontario and Quebec, the summer outlook includes heat waves beginning as early as late June. Though cooler spells are expected to interrupt the heat, the humidity will bring with it more frequent showers and powerful storms, meteorologists predict.

West Warms

Western Canada is expected to face some of the most extreme heat.

Across British Columbia, it’s a mixed bag. 

The Weather Network (TWN) predicts the coastal regions can expect near-seasonal temperatures, while the interior is likely to swelter under intense heat, particularly in July and August.

With below-average rainfall in the southern interior, wildfires and smoky skies could once again be a concern.

Wheatbelt Warmth

The Prairie region of Canada, Alberta, Saskatchewan, and Manitoba, are in for a hot and dry summer, especially during July and August.

Alberta, Saskatchewan and Manitoba all face increased wildfire risk, though the occasional thunderstorm could bring brief relief, according to TWN.

Maritime Mix

For Atlantic Canada, the summer is predicted to be warm and humid, especially in the Maritimes and western Newfoundland.

However, intermittent cold fronts could offer breaks from the heat.

According to TWN's summer forecast, the region should also be alert to potential tropical systems, as current patterns point to a "higher-than-usual" risk.

"On the other hand, we expect a quieter-than-normal season in the deep tropics (including the Caribbean), but more storms are expected to form north of the Main Development Region (MDR), and those storms would have a higher potential to impact North America," TWN reports.

In Canada’s North, warmer-than-usual temperatures are expected across the Northwest Territories, eastern Yukon, and Nunavut. 

Parts of the Yukon could experience above-average rainfall.
