Mount Pearl residents can expect a back-and-forth week of weather, with sunny stretches mid-week giving way to rain and cooler temperatures by the weekend, according to Environment Canada.
After a mostly cloudy evening on Monday, August 31, with a low of 10°C and a 40 percent chance of showers, Tuesday will bring a mix of sun and cloud and another 40 percent chance of showers with a high of 16°C. Winds from the northwest could gust up to 40 km/h.
Conditions improve Wednesday through Friday, with sunny skies and highs of 16°C, 17°C, and 19°C respectively — the warmest stretch of the week. But the clear days will not last. Saturday brings rain and a high of just 12°C, with showers continuing into Sunday. The temperature drop aligns with typical September weather for the Avalon Peninsula, where the transition from summer to fall brings more variable systems off the Atlantic.
Forecasters use data from the St. John’s International Airport weather station, about 5 km north of Mount Pearl. As of 6:30 p.m. Monday, it was mostly cloudy and 18°C in the area, with humidity at 68 percent and a westerly wind of 17 km/h. For comparison, September climate normals for the region show average highs of 17°C and lows of 8°C.
Residents planning outdoor activities are advised to enjoy the mid-week sunshine and prepare for cooler, wetter conditions by packing layers and rain gear ahead of the weekend.
