A Little Bit of Everything as Thunder Bay Hops Into Easter
Cloudy Skies and Mixed Precipitation Give Way to a Bright Easter Sunday
THUNDER BAY – WEATHER UPDATE – Easter weekend in Thunder Bay is shaping up to be a classic Northern Ontario patchwork of grey skies, light flurries, chilly mornings, and—yes—some golden sunshine just in time for Sunday celebrations. From soggy streets to snowy rooftops, Mother Nature has clearly been watching the weather roulette wheel again.
As of 6:00 AM EDT at Thunder Bay Airport, it’s a cool and cloudy morning at 1.9°C. The dew point matches the temperature exactly, giving us a humidity level of 100%—that’s about as damp as it gets without actual precipitation. Winds are light out of the west at 6 km/h, visibility is excellent at 24 km, and barometric pressure is sitting at 100.4 kPa, trending downward, a sign of change on the way.
Good Friday – Cloudy With On-and-Off Showers
Today will stay mostly cloudy with a 40% chance of scattered rain showers throughout the day. Winds remain light, and temperatures will climb to a modest high of 8°C. The UV index is at a moderate 4—so while the sun may play peekaboo, some rays might still sneak through the cloud cover. Keep that umbrella handy, just in case Mother Nature decides to give your plans a quick rinse.
Friday Night – From Raindrops to Flurries
Tonight continues with cloud cover and a lingering 40% chance of rain showers this evening. Later on, those showers could flip into flurries as the temperature dips below freezing to a low of -1°C. With winds up to 15 km/h, the wind chill could make it feel closer to -5°C. If you’re heading out late, or setting out any outdoor Easter decorations, brace for a frosty touch.
Saturday – Chilly Start, Brighter Finish
Saturday will be cloudy with a 40% chance of morning and early afternoon flurries. Winds shift to the northwest and pick up to 20 km/h by midday, adding an extra bite to the morning chill. Expect a high of 8°C, but the day will start off feeling much colder, with a wind chill around -5°C.
Saturday night brings clear skies and a sharp dip in temperature to -7°C, so if you’re prepping for a sunrise egg hunt on Sunday, gloves and a hat are a must.
Easter Sunday – Sunshine at Last
Sunday offers the best weather of the weekend. Expect clear skies and bright sunshine with a high of 9°C—perfect for outdoor brunch, egg hunts, or a peaceful spring walk. But don’t pack away the parka just yet. Clouds will roll in Sunday night, bringing a 30% chance of snow and a low around +1°C.
Monday follows up with more unsettled conditions—periods of snow or rain are expected with a daytime high of 6°C, and a continued 40% chance of snow or rain into Monday night with lows around zero.
What to Wear
Layering is your best bet this weekend. Today: raincoat or waterproof jacket for those off-and-on showers. Saturday: warm coat, gloves, and maybe a scarf for that wind chill and frosty morning. Sunday: sunglasses and spring layers, but still bring a jacket for the evening cooldown. And Monday? We’re back to water-resistant everything.
Historic Weather Note
Thunder Bay’s warmest April 18 on record reached a balmy 21.7°C, while the coldest dipped to a chilling -13.1°C. This year’s mix of modest highs and overnight lows in the negative zone makes it a middle-of-the-road spring—though one with plenty of variety.
Did You Know?
Thunder Bay’s unique position at the head of Lake Superior makes it especially prone to dramatic spring transitions. The massive lake’s lingering cold air can clash with warmer systems from the south, producing unpredictable shifts—snow one day, sun the next.
