Fog Advisory in Effect for Nipigon, Rossport, and Surrounding Areas
Dorion, Nipigon, Rossport, Cloud Bay, Kakabeka Falls — A thick blanket of fog has rolled in off Lake Superior’s north shore this Saturday morning, bringing visibility down to near zero in some locations. Environment Canada has issued a Fog Advisory, warning of significantly reduced visibility and hazardous travel conditions along Highway 17 and surrounding routes.
What’s Happening with the Weather Today?
As of 6:00 AM EDT, the temperature in Nipigon is sitting at a chilly -1.1°C, with a humidity level of 98% making it feel even damper than usual. Winds are coming from the southeast at 6 km/h, and the wind chill currently sits at -3°C. The barometric pressure is at 102.0 kPa and falling, suggesting some unsettled weather could be on the way.
The fog is expected to gradually lift by midday, although areas close to the lakeshore might see persistent patches clinging to the coast well into the afternoon. Once the fog dissipates, expect mainly cloudy skies with a 30% chance of showers in the afternoon. Temperatures will rise to a high of 7°C, though it’ll feel colder early on, with a wind chill of -6°C.
Winds will pick up a bit by noon, shifting to a southeast breeze at 20 km/h, and the UV index will hit 4, which is considered moderate — so toss on some sunscreen if you’re planning any extended time outdoors once the fog clears.
Tonight and Sunday Outlook
Tonight will remain mainly cloudy with a 30% chance of showers early in the evening. Fog patches are expected to redevelop overnight, particularly in areas close to the lake. Winds will ease off by evening, becoming light, with a low of -1°C.
Looking ahead to Sunday, April 13, the fog returns briefly in the morning but should clear out by midday. Skies stay mostly cloudy, and winds will once again shift from the southeast at 20 km/h by late morning. The temperature will climb slightly higher, reaching a mild high of 8°C. But don’t stash that umbrella too far — Sunday night brings a 70% chance of rain or snow, with a low around 0°C.
8:00 PM EDT Sunday 13 April 2025 – 6:00 AM EDT Tuesday 15 April 2025 Accumulating snow and occasional blowing snow causing hazardous winter driving conditions are possible. Untreated roads may become snow covered and slippery.
Historic Weather for April 12
Just for fun — and maybe to appreciate how mild it is — the record high temperature for April 12 in the region is 21.0°C, while the record low chills all the way down to a frosty -17.2°C. So, yes, -1°C may be foggy and cold, but it’s far from our worst spring day ever.
What to Wear?
If you’re heading out today, layer up with a warm jacket, gloves for the chilly morning wind, and consider water-resistant footwear in case showers roll in. And if you’re hitting the road, be extra cautious. Fog isn’t just mysterious-looking — it’s also a real hazard, especially when it hugs the curves of the north shore.
Foggy Fact of the Day
Did you know? The north shore of Lake Superior is particularly prone to fog due to the cold lake waters interacting with warmer air masses — especially in spring and early summer. That “rolling mist” isn’t just cinematic, it’s science!
