Crisp and Cloudy Start Leads to a Warm, Bright Day Across Greenstone
A Classic Northern Ontario Forecast: Fog, Chill, and Then a Glorious High of 22°C
GERALDTON – WEATHER – Monday, May 26, 2025 – Don’t be fooled by the frosty start—Geraldton is on track for a sun-warmed spring day that feels more like early summer. It’s a story of contrast this morning, with low temperatures and lingering fog, but the sunshine is ready to make an entrance.
As of 6:00 AM EDT, the temperature at Geraldton Airport hovered at a brisk 2.9°C, with skies mostly cloudy and visibility sitting at 16 km. Winds were calm, making the chill feel just a little more bearable. Barometric pressure sits at 102.8 kPa, a strong indicator of stable, pleasant weather on the way.
Fog patches are expected to dissipate this morning, giving way to a mix of sun and cloud with a high of 22°C this afternoon. The UV index is 6, so don’t let the morning clouds lull you into skipping the sunscreen—UV rays don’t care about cloud cover.
Tonight will be partly cloudy with a low of +3°C, so if you’re camping or out stargazing, bring an extra blanket.
Sunny Stretch Ahead: A Midweek Treat
Tuesday delivers clear skies in the morning, becoming a mix of sun and cloud in the afternoon. Temperatures climb to 23°C, and clear skies return Tuesday night with a warmer low of 7°C.
Wednesday and Thursday look absolutely gorgeous, with sunny skies and highs of 25°C both days—a rare streak of stable, sunny weather for late May in the north. Thursday night ends with a few cloudy periods, but nothing to dim the spring vibe. Overnight lows remain steady around 7°C to 9°C through the midweek.
All in all, it’s an ideal stretch of weather for outdoor projects, fishing trips, trail walks, and yes—even breaking out the barbecue.
Wardrobe Suggestion
This morning, bundle up with a warm jacket or hoodie—it’s chilly out there. But by the afternoon, you’ll want breathable, lightweight clothing and your favourite shades. A hat and sunscreen are highly recommended with that strong UV.
