A Mid-September Tease: Sunshine, Warm Temps, and the Hint of Thunder
DRYDEN – WEATHER – Just when you thought it was time to swap the shorts for sweaters and hot coffee for pumpkin spice, Mother Nature steps in with a sun-drenched reminder that September is still holding on to summer.
In Dryden and Vermilion Bay, today’s forecast is serving up sunny skies and warm temperatures that could have you back in sandals by lunch.
A Warm Morning and Even Toastier Afternoon
At 6:00 AM CDT this morning, it was mainly clear over Dryden Airport with the temperature sitting at a pleasant 13.8°C. Humidity was sitting at 91%, giving the morning a slightly dewy feel, while the south wind at 11 km/h gently nudged things along. The barometric pressure is a stable 102.4 kPa, suggesting fair weather for most of the day.
As the sun rises higher, expect that wind to pick up to 20 km/h from the south, helping temperatures climb toward a high of 24°C. With a humidex of 26, it’ll feel even warmer—a lovely reminder that fall doesn’t officially take over until the equinox. The UV index is at 5, which is considered moderate, so some sun protection wouldn’t go amiss if you’re outside for extended periods.
On this date in Dryden’s weather history, the record high was 29.7°C, while the record low dipped down to -0.6°C—a perfect illustration of how quickly things can swing this time of year in Northwestern Ontario.
Storms Brewing After Sundown
This evening, the sky will cloud over gradually, with a 60 percent chance of showers developing late and sticking around overnight. There’s also a risk of thunderstorms, so if you’re planning a night out or heading to the lake for a last dip, keep an eye on the sky and maybe don’t leave the windows down in the car. Winds will ease off to light speeds after sunset, and the overnight low will hover around 14°C.
Friday Brings More Clouds and a Side of Thunder
Friday, September 12, is expected to stay cloudy, again with a 60 percent chance of showers and that ever-present risk of a thunderstorm. The temperature will top out at 21°C, but the humidex will push it to feel more like 26°C. The UV index will be a moderate 4, so sun exposure isn’t a huge concern—but a raincoat might be a wise fashion statement.
The skies will clear somewhat Friday night, with cloudy periods and a low of 14°C. From there, the weekend looks like a warm and welcoming encore.
Weekend Outlook: Classic September Mix of Sun and Cloud
Saturday and Sunday promise to keep things bright and comfortable. Both days feature a mix of sun and cloud, with daytime highs of 24°C—great news for anyone squeezing in some late-summer camping, yardwork, or patio time. Overnight lows will be 10°C on Saturday and 11°C on Sunday, cool enough to appreciate a cozy blanket, but not quite sweater weather yet.
What to Wear?
Shorts and short sleeves are definitely back on the table today, but keep a light jacket or rain shell handy if you’re staying out into the evening. Footwear that can survive a sudden splash wouldn’t hurt either—just in case those thunderstorms decide to get dramatic.
Weather Trivia: Dryden’s “Paper” Forecast
Did you know Dryden is home to one of Canada’s smallest pulp and paper towns with its own airport? Thanks to its geography and industrial history, the area often experiences interesting microclimates—like foggy mornings followed by toasty afternoons—making it a meteorologist’s mini playground.
