Geraldton and Greenstone Weather Forecast – Grey Skies Hold Steady with a Damp Weekend Ahead
Overcast and Damp as Spring Hits the Brakes
Geraldton & Greenstone, ON – Thursday, May 22, 2025: Spring may be on the calendar, but it’s more of a waiting game in Greenstone this week. At 5:00 AM, it’s a damp 5.1°C at Geraldton Airport under cloudy skies, with 100% humidity making everything feel just a touch soggier than usual. The dew point matches the temperature, which means the air is fully saturated — hello, misty windows and dewy lawns. Winds are from the north-northeast at 13 km/h, and visibility is 16 km, giving us a murky but passable start. The barometric pressure is at 101.8 kPa, suggesting things are holding steady, at least for now.
Today’s forecast is a continuation of the gloom: cloudy with a 40% chance of showers hanging in the background all day. The north wind will strengthen to 20 km/h, adding a cool edge to an already chilly forecast. The high will only reach 6°C, a stark contrast to the more springlike weather hitting other parts of Ontario. The UV index is low at 2, so there’s no need to worry about sunburn — but you might want to prep for drizzle.
Cloudy and Damp Nights Continue
Tonight, the clouds hang tough with another 40% chance of showers and a low of +3°C. Winds from the north at 20 km/h will keep the air cool and damp, and don’t expect much change heading into Friday.
Unchanging Skies Through Saturday, But Hope on Sunday
Friday starts much like today: cloudy with a 40% chance of early morning showers, a high of 7°C, and persistent north winds at 20 km/h, which will ease by midday. The evening will remain cloudy with a 40% chance of continued showers and a low of +1°C.
Saturday offers more of the same — cloudy skies, a 40% chance of showers, and a slightly warmer high of 10°C. That night will be a bit milder at +2°C, though still mostly cloudy.
There is light at the end of the cloud tunnel: Sunday brings a mix of sun and cloud, and with it, a much more pleasant high of 15°C — the kind of day that finally feels like spring is on the rebound. Sunday night remains partly cloudy with a low of +3°C.
What to Wear?
Think layers with waterproof outerwear — a hooded jacket, sturdy shoes, and maybe a warm drink in hand. Temperatures are chilly enough to warrant gloves in the morning, and with off-and-on showers, an umbrella or packable raincoat is a smart accessory.
