A Clear and Cool Start, with a Sunny Finish
Dryden & Vermilion Bay, ON – Wednesday, May 21, 2025: If you enjoy spring mornings with a side of fresh air and a promise of sunshine, today’s forecast is tailor-made for you. As of 5:00 AM at the Dryden Airport, skies are mainly clear and the temperature is a brisk 5.3°C. The dew point sits at -1.6°C, with humidity at 61%, so it feels fresh but not damp. A light east-northeast breeze at 13 km/h adds a bit of chill, and with visibility at 16 km, the day is off to a crisp and clear start. The barometric pressure is holding at 101.9 kPa, suggesting stable weather conditions.
Today’s forecast? Wall-to-wall sunshine! The skies will stay clear, with the northeast wind increasing to 20 km/h and gusting up to 40 km/h. That breeze will add a bit of flair to your hair and your afternoon plans, but with a high of 16°C, it’s shaping up to be a top-tier spring day. The UV index climbs to 7, which is high — so whether you’re walking the pup or planting in the garden, don’t skip the sunscreen.
Calm and Clear Tonight
The good news doesn’t stop at sundown. Tonight stays clear, with that same northeast wind gusting through the early evening before calming down later. The overnight low will be +3°C, so it’s a bit chilly but frost-free — great news for anyone with early garden blooms.
Thursday Brings More Sunshine, Then a Few Clouds
Thursday continues the winning streak with another sunny start, although clouds will begin to build in the afternoon. Winds will swing around from the north, strengthening to 20 km/h and gusting up to 40 km/h, which could make it feel a touch cooler than the forecasted high of 16°C. The UV index remains high at 6, so it’s still a day to protect your skin if you’re soaking up those morning rays.
Thursday night clears up again with an overnight low of +3°C, consistent and comfortable for late May.
Friday keeps the good times rolling with sunny skies and a high of 18°C, inching us closer to proper short-sleeve weather. Cloudy periods are expected Friday night, but with a mild low of 6°C, it’ll still be a pleasant evening for a bonfire or stargazing.
What to Wear?
Mornings like these call for a layered approach: a fleece or light jacket to start your day, with lighter clothing underneath for the warm afternoon sunshine. Windproof outerwear is a plus with gusts kicking up to 40 km/h. And yes, it’s officially sunscreen season — the UV index isn’t messing around.
