Grimsby residents can look forward to a sunny Saturday, April 11, 2026, before more unsettled weather arrives to start the new week. While conditions are clear today, Environment Canada reports that temperatures will drop near the freezing point overnight, and rain is expected to return by Sunday.
As of 9:00 a.m. this morning, the temperature at the Vineland Station was 4.1°C. For the remainder of Saturday, skies are clearing and temperatures are expected to reach a high of 10°C. Residents planning to spend time outdoors should take note of a high UV index of 6. While there are currently no weather alerts in effect for the Niagara Region, the clear conditions will be short-lived, with overnight lows dipping to 1°C and a potential for frost on surfaces.
The pattern of wet weather is set to return on Sunday, April 12, with periods of rain forecasted. The following Monday and Tuesday will bring cloudy skies and a 40 percent chance of showers, though temperatures are expected to climb to 15°C. By Wednesday, April 15, the weather will warm further, reaching a high of 17°C, which is above the seasonal normal of 11°C.
The return of these showers is consistent with local climate trends, as April is historically one of the wettest months in the area, typically receiving about 101 mm of precipitation. These conditions follow a forecast from the Old Farmer’s Almanac, which predicted a mix of rain and cooler-than-normal temperatures for Ontario this spring. While the region generally experiences a moderate climate that supports local agriculture, residents should remain prepared for variable spring weather and potential frost as the season progresses.
