Residents in Kingston can expect a mix of cool temperatures and damp conditions as the week begins, though warmer weather is on the horizon. According to Environment Canada, Sunday, April 19, 2026, will remain cool, as the region sees a transition from morning rain and snow toward mainly cloudy skies.
There is a 60 percent chance of rain showers during the day today, which may change to a 40 percent chance of flurries by late evening. While there are currently no active weather alerts for the area, the Cataraqui Conservation Authority maintains a water safety statement for inland lakes and streams, advising residents to use caution near water due to high flows resulting from recent rainfall and snowmelt.
The unsettled weather is expected to stick around through Tuesday, with a 40 percent chance of showers persisting. Residents can plan for a shift in the weather mid-week, however, as temperatures are forecast to climb steadily. Daytime highs are expected to reach 15°C by Wednesday, followed by 17°C on both Thursday and Friday, offering a warmer end to the work week.
Those spending time outdoors should prepare for variable spring conditions by dressing in layers. While these temperatures are a welcome sign of the season, they follow a period of typical April volatility where the city usually sees a mix of rain and cool air influenced by the 5.2°C water temperatures of Lake Ontario.
