Thursday morning weather brief | August 7, 2025

By Eddie Sheerr·August 7, 2025 · 6:30 AM

Good Thursday morning!

We are waking up to clear skies and comfortable temperatures across the majority of the Province. Readings are generally into the teens, with a few exceptions.

The weather across the region today will be dominated by high pressure moving in. This will result in another sunny day across Atlantic Canada. The wind will be slightly higher today and will generally blow from a westerly direction. The exception may be on the Avalon, where wind direction varies slightly from place to place. Guidance suggests the wind will be from the west this morning, turning north this afternoon, and then going south this evening. This is partly due to the high building and partly due to Tropical Storm Dexter passing well to our southeast today.

Temperatures today will climb into the middle and upper 20s for much of the region. Parts of Labrador are under a HEAT WARNING for the next several days due to temperatures expected to be near 30 and lows above 16. I suspect the Heat Warning may be expanded to more areas as the entire Province is going experience some of the most widespread heat I can remember forecasting in my 12+ years living here. Temperatures are forecast to run as warm as 10º above normal for the next several days.

Additionally, very little rain is forecasted for the same time frame. The image below shows the predicted precipitation over the next 10 days. While this means we are in for some great summer weather, it means we are not going to see any help from Mother Nature with respect to the ongoing fires. In fact, the fire risk is expected to continue increasing. Please remember there is a Provincial (NL) Fire Ban in place until at least September 7, 2025.

AIR QUALITY ALERTS

Ash from ongoing wildfires has been reported falling in Victoria and the surrounding area. Wildfires significantly impact air quality, as smoke contains fine particles and pollutants that can pose health risks, particularly to vulnerable groups such as children, seniors, and individuals with respiratory conditions.

High pressure building across the region will lead to sinking air and may result in air quality becoming worse for some areas near the fires over the coming days.

For the latest air quality conditions and health guidance, visit the Air Quality Health Index (AQHI) and AQmap.

Special Air Quality Statements remain in effect for:

• St. John’s and vicinity

• Bonavista North

• Gander and vicinity

• Terra Nova

• Clarenville and vicinity

• Bonavista Peninsula

Air Quality Warnings have been issued for:

• Avalon Peninsula North

• Grand Falls-Windsor and vicinity

• Bay of Exploits

AQHI (Air Quality Health Index) Forecasts:

• St. John’s: Low risk today with maximum values of 2 (Low Risk), except 7 (High Risk) in areas impacted by smoke, through Thursday night.

• Grand Falls-Windsor: Forecasted as Moderate Risk overall, with peak values of 10 (High Risk) in smoke on Wednesday, and 2 (Low Risk), except 7 (High Risk) in smoke, through Thursday night.

Residents are advised to limit outdoor activity during periods of heavy smoke and to follow public health recommendations, especially if experiencing symptoms such as coughing, throat irritation, or difficulty breathing.

WILDFIRE UPDATE

Late last evening, Fisheries, Forestry, and Agriculture, Newfoundland and Labrador, released a statement about the status of the fires burning on the Island.

The Kingston wildfire remains very hot and smoky. Today ground crews concentrated their efforts on the southern edge while three water bombers, three helicopters, and a bird dog aircraft provided aerial suppression. Monitoring will continue overnight. The Incident Management Team anticipates taking a similar approach to attack the fire tomorrow.

Crews are reporting a good day on the wildfire in Holyrood. Air and ground crews have made progress suppressing hot spots within the area, however, there is still fire activity on the western edge. Tomorrow will see a continuation of this approach, with one helicopter and ground crews continuing to work hot spots. Additional air support will be provided if needed.

The Martin Lake wildfire has expanded along the southern edge but remains contained along the northeast edge. The approximate size of the fire is 220 hectares. Three 802 aircrafts provided by New Brunswick worked the southwest edge. Sprinklers have been installed on the cabins closest to the fire along Martin Lake for added structure protection. Tomorrow, one water bomber, three 802 aircrafts and three helicopters will continue with arial suppression with ground support when possible.
