Warm weekend, but keep an eye on coastal fog and seaside winds
Sunshine and above‑seasonal readings will be the rule for much of Newfoundland and Labrador today, with daytime highs generally in the low to mid‑20s Celsius. While inland communities will enjoy the warmer values, parts of the coast are likely to remain cooler and at risk of fog and stronger gusts this afternoon and into tonight.
Across eastern districts, St. John’s is expected to reach about 22 °C today with mostly sunny skies and a UV index of 7 (high). Nearby Bonavista should see similar conditions and a top near 23 °C, although some coastal spots may only climb to around 19 °C. Inland locations can feel noticeably warmer: a humidex near 27 is possible Sunday for some interior sites.
Fog forming overnight, then lifting Sunday
Low cloud and fog patches are forecast to develop in a number of low‑lying and coastal areas overnight, with morning fog expected to thin or dissipate by Sunday. Nighttime lows will generally be in the low to mid‑teens Celsius, dipping into the single digits in the lowest terrain.
- Nighttime lows: around 13–14 °C in many places, with 8–10 °C in low‑lying or sheltered areas.
- Sunday highs: mostly in the 21–25 °C range depending on proximity to the coast.
- UV levels: generally 6–7 (high) this weekend — sunscreen and sun protection are advised.
On the south coast, Channel‑Port aux Basques should see sunny skies with a high near 20 °C, but evening cloud will increase. The central region, including Gander, is forecast to be sunny with a high near 24 °C and a humidex around 26. The west coast around Corner Brook will be mainly sunny with highs close to 20–24 °C, depending on the exact location.
Gusty winds for the northern peninsula
Marine and exposed coastal zones on the northern peninsula should prepare for gustier conditions. Wind speeds are expected to rise this afternoon, with southwest winds gusting to about 60 km/h at times and sustained speeds in the 30–40 km/h range. These gusts will ease overnight to the moderate range.
| Area | Today (high) | Tonight (low) |
|---|---|---|
| St. John’s / Avalon | 22 °C | 13 °C |
| Bonavista | 23 °C (coast near 19 °C) | 14 °C |
| Channel‑Port aux Basques (South Coast) | 20 °C | 12 °C |
| Gander (Central) | 24 °C | 12 °C |
| Corner Brook (West) | 20–24 °C | 11 °C |
Forecasters note that coastal temperatures can be several degrees cooler than nearby inland readings and that fog can substantially reduce visibility for drivers and marine traffic. Boaters and coastal travellers should monitor local updates for changes in wind and visibility.
Practical advice
With UV indexes in the high range across much of the province, take basic sun‑safety measures: wear sunscreen, protective clothing, and a hat, and seek shade during peak sun hours. For those in low‑lying coastal areas, allow extra travel time Sunday morning in case patchy fog lingers.
Those planning outdoor activities should also be mindful of gusty winds on the northern peninsula today. Secure loose objects outdoors and exercise caution on exposed headlands and piers. If you are heading out on the water, check the latest marine forecasts and ensure appropriate safety equipment is on board.
Conditions are expected to moderate Sunday as many fog patches dissipate and cloud cover increases in some areas. Continue to consult local forecasts for updates, particularly if you are in a coastal or exposed location where conditions change quickly.
