It’s official — St. John’s has now hit 20 °C or warmer for the 84th time in 2025, setting a new all-time record. The last three days have also topped 20 °C, which, according to Environment and Climate Change Canada meteorologist Rodney Barney, marks a record streak for October. It’s been an incredible run of late-season warmth — but as you’ll see below, the pattern is about to shift.

As of late afternoon Thursday, the heaviest rain across eastern Newfoundland was focused over the southeastern Avalon Peninsula. Many areas across the east were still seeing pockets of heavier rain, but that will gradually ease through the evening.

A brief lull is expected through central Newfoundland (Gander to Grand Falls–Windsor) before more showers rotate through later tonight. Out west, rain continues along with some wet snow showing up in the Long Range Mountains — especially along Route 430 near Wiltondale and Gros Morne. It’s mostly confined to higher terrain and isn’t expected to cause travel issues.

A strong push of colder Labrador air is spilling south tonight. Over the next few hours the Avalon will still be in the mid teens, but by midnight, temperatures fall sharply, lows will be in the lower to middle single digits across most of the Island. By early Friday morning, it will feel like true October weather again: brisk, breezy, and several degrees cooler than we’ve grown used to.

Friday’s forecast calls for highs of 6–9 °C across most of Newfoundland, with limited sun. Central and western areas will hover in the single digits, while the Avalon sees 8–10 °C at best.

In Labrador, it’s even cooler overnight with freezing temperatures for many, and a mix of rain and wet snow expected in the west. Snow will push from Labrador City toward Churchill Falls through the first half of the day, but should melt quickly as temperatures rise near 8–11 °C during the afternoon. The snow is along a warm front.

Windy Overnight, Then Improving

Winds will ramp up tonight, especially for northern and northeastern Newfoundland. Gusts could reach 70 km/h in St. Anthony and 50–60 km/h in exposed coastal areas like Bonavista and Twillingate before easing through Friday morning.

By afternoon, the low pulls away, and gradual improvement sets in from west to east. Expect a mix of cloud and sun for much of the Island by late day.

The Weekend Outlook

After a chilly Friday, we rebound nicely for the weekend.

  • Saturday: A mild return with highs near mid teens for eastern and central Newfoundland, around 10 °C in the west and north. Expect a few showers but generally a pleasant fall day.

  • Sunday: Drier and slightly cooler, with highs around 9–10 °C on the Avalon and 8–9 °C in western and northern Newfoundland.

  • Labrador: A few rain or snow showers Saturday, followed by a sunny, calm and seasonable(ish) Sunday.

Early Next Week: Sunshine Returns

Looking ahead to Monday and Tuesday, a ridge of high pressure will dominate. Plenty of sunshine province-wide and mild temperatures in the low to mid-teens will make for comfortable conditions — just in time for Election Day. Travel looks smooth across Newfoundland and Labrador with no weather-related issues expected.
