A Frosty Morning with Flurries on the Horizon
Geraldton–Greenstone, ON – Sunday, April 6, 2025 – Northern Ontario is waking up to a stubborn chill this morning in Geraldton and the Greenstone region. At 6:00 AM, the temperature hovered at -10.9°C under mostly cloudy skies. Humidity is at a bracing 84%, with a dew point of -13.1°C keeping the air dry and crisp. Winds from the west-southwest at 8 km/h are enough to drag the wind chill down to a sharp -16. Visibility sits at 16 km, and barometric pressure is holding at 101.7 kPa—stable for now, but don’t let that lull you into thinking winter’s done just yet.
Sunshine, Flurries, and the Great Spring Tease
Today, the region can expect a classic northern April rollercoaster. It’ll start off mostly sunny, giving just enough hope for spring before increasing cloudiness near noon ushers in a 60% chance of flurries for the afternoon. The wind will shift to the northwest at 20 km/h, gusting up to 40 km/h, knocking the wind chill to a frosty -19 this morning and -8 by afternoon. The high will barely reach -2°C, so don’t even think about putting away your winter gear yet. The UV index will creep up to 4, which is moderate—so a bit of sunscreen for exposed skin isn’t the worst idea.
Tonight, it stays mainly cloudy with another 60% chance of flurries lingering. Winds will push in from the north at 20 km/h, gusting again to 40 km/h. Overnight lows plummet to -14°C, and with the wind chill, it’ll feel more like -22. If you’re venturing out, think arctic expedition, not springtime stroll.
Monday: A Chilly Mix of Sun and Cloud
Monday offers a break from snow, but not the cold. Expect a mix of sun and cloud with a high of -6°C. The wind remains persistent from the north at 20 km/h, keeping the morning wind chill at a brisk -23 and -12 in the afternoon. The UV index will sit at 3, so even in the cold, the sun’s strength is creeping up.
Monday night continues the theme of cloudy periods and cold temps, with a 30% chance of flurries and a low of -19°C—seriously, this is peak sweater-under-the-coat season.
Tuesday and Beyond: Sunshine and the Slow Rise of Spring
Finally, some good news: Tuesday will be sunny, with a high of -1°C. Sure, it’s still below freezing, but by then it’ll feel practically tropical. Tuesday night is clear and still chilly with a low of -14°C.
By Wednesday, we officially hit the plus side of the thermometer with a sunny high of +5°C. And looking ahead to Thursday and Friday? We’re talking daytime highs of 9°C to 10°C. Spring might not be kicking in the door just yet—but it’s definitely peeking through the window.
April 6 Weather: A Look Back
Historically, April 6 has brought Geraldton some surprises. The record high for today is a balmy 18.3°C, while the coldest was a biting -27.5°C back in 1972. So while it feels cold this year, we’re thankfully not breaking records—just enduring a late-season cold snap.
