Check the live forecast above for today’s conditions across Newfoundland and Labrador. Then plan layers and travel timing based on the regional differences between the Avalon, the west coast and Labrador.
What makes Newfoundland and Labrador weather so changeable?
Newfoundland sits where the cold Labrador Current meets the warm Gulf Stream. This collision creates fog, rapid temperature shifts and the famous “iceberg alley” winds. Labrador is subarctic: winters are long and snowy, summers short and cool. Always expect a sea breeze near the coast and stronger gusts along the Northern Peninsula.
What should I watch for in specific areas?
Check nl weather corner brook before heading into the Humber Valley—lake-effect snow can pile up fast in winter. For east coast trips, clarenville nl weather often shows a delayed warm-up due to lingering sea ice. Mariners need the weather office nl marine bulletins for wave heights and ice charts. The nl weather radar live feed above shows incoming rain or snow bands, so refresh it before leaving.
How reliable are long‑range forecasts for NL?
Maritime weather is hard to pin down beyond five days. For weather in newfoundland and labrador 10 days, treat day 6–10 as a trend, not a guarantee. The nl weather radar live hourly loop is better for now‑casting. If you need precise plans, use the nl weather hourly breakdown on the 10‑day page. For a broader outlook, the nl weather 14 day forecast can show possible storm tracks but expect revisions.
Why is fog so common in Newfoundland?
Warm moist air from the Gulf Stream passes over the cold Labrador Current, causing condensation. Fog can roll in within minutes, especially along the Avalon and Burin Peninsulas. Check visibility in the live forecast above before driving.
Does Labrador get colder than the island?
Yes. Labrador’s interior is subarctic: winter lows near –30°C are normal. Coastal Labrador is slightly milder but still much colder than St. John’s. Always pack extra base layers when travelling north of Happy Valley-Goose Bay.
What is “weather office NL marine” used for?
Environment Canada’s marine forecast covers winds, waves and ice for coastal and offshore waters. Fishermen, ferry crews and recreational boaters rely on it. Find it linked from the live above or directly from weather.gc.ca.
