Summer 2025 weather

From The Weather Network, Canadas Summer Forecast… by Doug Gillham, May 28, 2015

“…While most of Canada will experience a warm summer, we are highlighting the potential for temperatures to be much warmer than normal across parts of the country (especially during July and August), stretching from the Rockies to northwestern Ontario. Those areas face a risk of extended heat waves and a few days of extreme heat. The excessive heat could also occasionally extend into British Columbia, but we do not expect it to be as persistent there as it will be across the Prairies.”

“In Eastern Canada, from the Great Lakes to Atlantic Canada, we anticipate a warm and humid summer. While a few heat waves are possible, we do not expect persistent or extreme heat. For most of the region, high temperatures should be near normal or slightly above normal, but nighttime temperatures are forecast to be warmer than normal due to the muggy conditions.”

“…Eastern Canada could experience periods of dry weather, but we do not expect widespread or prolonged drought conditions this summer from east of the Great Lakes to Atlantic Canada. That region will see more frequent showers and thunderstorms, with a risk of strong to severe storms and torrential downpours at times.

“However, keep in mind that summer thunderstorms are notorious for being localized, and we often see areas that repeatedly miss out on rain in close proximity to places that have a surplus.

Nova Scotia, New Brunswick & P.E.I.

A warm and humid summer is expected across the region, including Halifax, Fredericton, and Charlottetown, but occasional cold fronts will bring more refreshing conditions at times.

While there should be dry stretches, we expect that showers and thunderstorms will be frequent enough to avoid widespread or prolonged drought, and to bring rain totals to near normal or above normal across the region.

As we get deeper into the season, we will closely watch the tropics. A more typical Atlantic hurricane season is expected, but the anticipated jet stream pattern would bring an elevated risk for a tropical system to impact the region.

Extracts from Above normal heat and rain forecast for summer in Nova Scotia
by Ian Fairclough in Chronicle Herald May 28, 2025

“The summer forecast from The Weather Network has warmer than usual temperatures for Nova Scotia during June, July and August…While there could be periods of dry weather, the network said it doesn’t expect widespread or prolonged drought conditions from the Great Lakes to Atlantic Canada. However, there is an expectation of more frequent showers and thunderstorms, with more rain than normal in southwestern and central parts of the province and a risk of strong to severe storms and torrential downpours at times. While the threat of more intense and larger wildfires increases with the effects of climate change, even if the rain prevents that here, Nova Scotia could still feel the impacts of fires further west.”

“…The forecast of more rain and more potential for torrential downpours also means it’s important to be aware and pay attention to any warnings or alerts of thunderstorm activities. ”

“Dan Stovel, the regional emergency management co-ordinator for Kings County, said the forecast is a reminder that people need to watch out for and pay attention to warnings and alerts from Environment Canada and regional or provincial emergency management organizations. ”

“People should be aware of what heat warnings entail,” he said. ”

“Last year, there were 16 days of heat warnings in Kings County, which is one of the hottest in the province.

“…In the last two years, five people have died in flooding in the Annapolis Valley during heavy rain events.”
