Ontario's April forecast for 2026 is in and here's what's in store

Even though we're less than two weeks in, it's safe to say that March has already been unpredictable across southern Ontario, with temperatures climbing into the high teens, followed by freezing rain, strong winds, and an upcoming wintry system this Friday.

If the past week is any indication, April is set to continue this turbulent pattern, and unfortunately, the snow is likely to linger for a while longer.

According to the Old Farmer's Almanac long-range forecast for southern Ontario, April is shaping up to be a month filled with rain, sunny breaks, and surprise — more snow. The month is expected to start off mild, with rainy and warm conditions between April 1 and 8.

Between April 9 and 15, periods of showers are expected, followed by sunny but cold weather. From April 16 to 25, more rain and even snow showers are expected, followed by sunny but chilly conditions.

The last week of the month is predicted to offer cool conditions with occasional showers. Overall, the forecast predicts an average monthly temperature of 5 degrees C, which is about 1 C below normal, and a precipitation total of 75 mm, which is roughly 5 mm above average.

Based on the same forecast, the rest of March will be just as unsettled. Between March 20 and 31, southern Ontario is in for more rain and snow, alongside periods of warmth.

In its spring forecast for 2026, the Old Farmer's Almanac also notes that the season across southern Ontario will likely be cooler than normal, with above-average precipitation in the north and below-average precipitation in the south. April is expected to bring a combination of rain and snow, followed by scattered thunderstorms throughout May.

The Weather Network's spring outlook for Ontario also paints a similar picture of the upcoming season, noting that "warm weather will lack commitment through March and well into April." Although periods of mild weather are still expected, winterlike conditions are expected to persist, which could extend the ski season, as well as delay the start of the growing season.
