Spring Sunshine and Sub-Zero Starts for Northern Ontario
SIOUX LOOKOUT – WEATHER – Residents in Sioux Lookout and Pickle Lake are waking up to a crisp northern morning, where the mercury is still clinging to winter — but don’t be fooled by the frosty start. The sun is set to make a welcome appearance today, bringing the kind of springtime warmth that could almost make you forget it was -3°C just a few hours ago.
Clear Skies and Climbing Temps Today, But Keep a Raincoat Handy
As of 6:00 AM CDT, the temperature at Sioux Lookout Airport is a chilly -2.7°C, with a dew point of -3.6°C and humidity sitting at a high 94%, making the air feel extra brisk. Light southeast winds are moving at just 4 km/h, creating a wind chill of -4. Visibility is clear at 24 km, and the barometric pressure is at 101.5 kPa and falling — a sign that change is indeed coming.
Today’s forecast brings a mix of sun and cloud, with the temperature making an encouraging leap up to a high of 12°C. The UV index hits a moderate 5, so if you’re outside for long — especially near reflective surfaces like snow or water — don’t skip the sunscreen.
By tonight, skies remain partly cloudy with a 30% chance of showers sneaking in during the evening. Winds stay gentle, maxing out at 15 km/h, and the temperature will dip to -4°C. With a wind chill expected to feel like -8°C overnight, it’s back to toque-and-gloves territory after dark.
A Damp Turn Ahead: Showers and Snow Mix Midweek
Tuesday starts off mainly cloudy with a high of 9°C and a 40% chance of showers late in the afternoon. Morning wind chills around -7°C will remind everyone that it’s still early spring in the north. Southeast winds pick up to 20 km/h by late morning.
Tuesday night brings more unsettled conditions — cloudy skies with a 60% chance of rain or snow and a low of +1°C. Wednesday carries on with the same mood, bringing a 60% chance of rain or snow and a high near 8°C. Evening flurries or rain showers are also possible as temperatures dip to zero.
Thursday holds steady in the cloud department, with a high of 10°C and continued overnight lows around the freezing mark. Not quite patio weather yet, but we’re getting closer.
What to Wear Today
It’s a “layers-on, layers-off” kind of day. Start your morning with a warm base and a jacket, especially if you’re out before the sun warms things up. As temperatures rise into the double digits, you can peel back the outerwear — just keep a rain jacket or umbrella close by for those sneaky evening showers. And don’t forget gloves if you’re out late — that wind chill won’t be kind after sunset.
Northern Weather Nugget: Record-Breaking Extremes
Sioux Lookout’s April 21 record high is a surprising 22.0°C, reached in 1987 — yes, tank tops in April do happen here (rarely). Meanwhile, the record low for this date is a wintry -17.8°C, set back in 1940. Today’s mild 12°C high falls comfortably in the middle, but it proves spring in the north is all about contrasts.
