Heat warnings issued for Maritimes as hot, humid weather persists until Saturday

Residents of the Maritimes are bracing for a significant heat wave, with Environment Canada issuing warnings for high temperatures and humidity expected to persist until Saturday. The hot, humid air mass, which has affected Ontario and Quebec, is forecast to bring uncomfortable conditions across New Brunswick, Nova Scotia, and Prince Edward Island.

Winds are going to come around from the north or northwest, and that’s actually going to bring in cooler and drier air that’s originating from northern Quebec and areas of Labrador.

Temperatures are predicted to exceed 28 C on Thursday, with humidex values making it feel as high as 42 C, particularly in New Brunswick. Coastal areas, however, may offer some respite due to the cooling influence of the Atlantic Ocean. Meteorologist Ian Hubbard advised residents to avoid strenuous outdoor activity during the hottest parts of the day, stay hydrated, and keep homes cool by drawing blinds.

Avoid being outside during the hottest part of the day, but I know that’s not always possible for people … drink lots of water, replace fluids if you feel thirsty. Try to keep blinds and shades drawn to keep sunlight out of your home.

Relief is anticipated by Sunday as cooler, drier air originating from northern Quebec and Labrador is expected to move into the region. This shift in weather patterns follows severe thunderstorms that caused power outages and flooding in parts of Ontario and Quebec earlier in the week amid the ongoing heat. Maritimers are encouraged to take advantage of the cooler coastal air as a temporary escape from the inland heat.

One of the benefits of living on the coast like we do is that the air is certainly cooler along the coast … those Atlantic Ocean waters tend to have a really strong influence on the air temperature, and can provide some relief there as well.
