A dense fog advisory for Prince Rupert and the North Coast is expected to lift near noon on Monday, August 17, 2026, after reducing visibility to near zero earlier in the day. Environment Canada issued the Yellow Advisory at 8:21 a.m. PDT, warning drivers on sections of Highway 16 to slow down and use extra caution.
At Prince Rupert Airport, visibility was down to just 0.6 kilometres at 10:22 a.m., with 100 percent humidity and a light south-southwest wind at 5 km/h. The temperature sat at 13.1 C. Fog patches may redevelop overnight Monday into Tuesday morning, but conditions should clear by midday.
The week ahead brings a mix. Tuesday stays cloudy with periods of drizzle and highs near 14 C. By Wednesday, skies are expected to turn sunny, with daytime highs climbing to 17 C Wednesday and 19 C Thursday and Friday. Some cloud and a chance of showers could return on the weekend.
Fog is a familiar challenge in Prince Rupert, one of Canada’s rainiest and least sunny cities. The community averages about 2,620 mm of precipitation and only 1,245 hours of sunshine each year. Its position on the North Coast, close to cool Pacific waters, makes autumn and winter fog especially common.
Low visibility can also affect marine travel. BC Ferries routes linking Prince Rupert to Port Hardy and Graham Island may experience delays when fog rolls in. Travellers are encouraged to check current conditions before heading out.
