From Frosty Start to Tank Top Territory — Northwestern Ontario Feels the Spring Surge

A Cool Morning Gives Way to a Scorching Spring Day

Dryden and Vermilion Bay are enjoying a calm and sunny start to this Sunday, with temperatures just above freezing at 3.2°C as of 6:00 AM at the Dryden Airport. Winds are coming in gently from the northeast at 5 km/h, and the air is fairly saturated with 89% humidity — so if it feels a little brisk stepping out the door, you’re not imagining it. Visibility is slightly reduced this morning at 16 kilometres, likely due to lingering early morning mist.

But don’t let the current chill trick you — this day is heading for a beautiful and dramatic turnaround. The barometric pressure is at a steady 101.7 kPa, and sunshine will continue all day long. By late morning, winds will shift to the southeast and pick up to 20 km/h, helping drive temperatures up to a balmy high of 23°C. With a UV index of 7 — considered high — it’s definitely a “hat and sunscreen” kind of day. And yes, it’s now officially safe to store the snow shovel.

Tonight: Calm and Clear Under the Stars

Tonight remains clear and pleasant. The southeast wind will ease after midnight, becoming light, and temperatures will settle at a mild low of 9°C. It’s a perfect spring evening — ideal for a firepit night or some quality stargazing under unspoiled skies.

Monday: Even Warmer, But Still Not the Warmest This Week?

Monday ups the ante with more sunshine and an impressive high of 25°C. Winds will swing around from the south at 30 km/h, gusting up to 50 — a perfect excuse to let the laundry dry the old-fashioned way. The UV index sticks at 7, so SPF is still your trusty sidekick.

Monday night stays clear and seasonably warm, with another low of 9°C. A truly lovely stretch of spring weather continues… at least for now.

Tuesday and Wednesday: Cooling Trend Returns

Tuesday shifts the mood with a mix of sun and cloud and a 30 percent chance of showers. The high dips to a still-pleasant 17°C — not bad, just a little more grounded. Tuesday night is where things take a sharp turn, with cloudy periods and a drop to a chilly zero degrees. Frost alert? It’s possible.

Wednesday sees sunshine return with a high of 14°C, while the night will again flirt with freezing, staying just at the zero mark. It’s that classic spring balancing act — t-shirt by day, jacket by night.

What to Wear

Today and Monday scream light layers, breathable clothes, and UV protection. By Tuesday night and Wednesday morning, you’ll want to swap the sandals for something a little more fleece-lined. Layers are key for navigating these temperature rollercoasters.

Weather Trivia: Dryden’s Climate Quirks

On May 4th, Dryden has seen its share of wild weather. The record high was a sizzling 27.7°C set in 2001 — right in line with Monday’s forecast. The coldest May 4th on record dropped to a frosty -6.2°C in 1967. This year’s high of 23°C with a start at just 3°C proves once again: if you don’t like the weather in Dryden, just wait a few hours.
