Passengers should expect changing conditions around airstrips and confirm flight schedules directly with their airline.

Peawanuck is forecast to see west winds of 40 km/h gusting to 60 km/h, while Summer Beaver remains at northwest 30 km/h gusting to 50.

Low cloud and scattered showers may also affect visibility.

Saturday — Best Overall Window

Saturday currently offers the strongest general flying conditions of the three days.

Big Trout Lake and Fort Severn turn sunny, while Summer Beaver sees a mix of sun and cloud. Peawanuck also improves to a mix of sun and cloud.

Late Saturday night, temperatures near Hudson Bay approach freezing and rain showers could begin mixing with flurries.

Regional Three-Day Trend

Thursday: Cool, breezy and showery, with inland highs generally around 14°C and Hudson Bay communities near 8°C to 10°C.

Friday: Cooler and still windy. Peawanuck reaches only 6°C, while Summer Beaver is near 10°C.

Wardrobe Recommendations

October weather has arrived.

A wind-resistant jacket, sweater or fleece and waterproof footwear will be useful Thursday and Friday.

For Fort Severn and Peawanuck, warmer layers are increasingly important. Friday’s high near Peawanuck is only 6°C, and overnight temperatures approach freezing by the weekend.

Fly-in passengers should keep a warm layer and rain shell in carry-on baggage in case weather creates longer waits around an airstrip.

Weather Trivia

October marks the point when mixed precipitation begins appearing regularly in forecasts near Hudson Bay.

At Peawanuck, Saturday night’s forecast already includes a chance of rain showers or flurries as temperatures fall to around 1°C.

That transition generally arrives earlier along the Hudson Bay coast than in communities farther south because of latitude, colder air masses and the strong influence of the bay.
