Kingston, Ontario is in for a stretch of hot and sunny days to start the week, but Environment Canada warns that the pleasant conditions come with a very high UV risk, and a shift to wetter weather is just days away. Temperatures are expected to climb to 26 C on Monday and 28 C on Tuesday, with the humidex making it feel even hotter.

According to the Environment Canada forecast, Tuesday will feel like 33 with the humidity, and the UV index will hit 9, or very high, both days. That means anyone spending time outside, especially between 11 a.m. and 3 p.m., faces a quick risk of sunburn. Environment and Climate Change Canada advises staying in the shade, wearing protective clothing and sunglasses, and reapplying sunscreen every two hours or after swimming or heavy sweating.

“Very high to extreme UV index levels of 8 or more mean you should not stay too long in the sun, especially between 11 a.m. and 3 p.m.,” Environment and Climate Change Canada’s sun safety guidance states. Unprotected skin can burn rapidly on clear, sunny days like those expected Monday and Tuesday.

The dry weather will not last. Tuesday night brings a 60 per cent chance of showers, with cloudy skies and a low of 18 C. The chance of rain continues Wednesday and Thursday at 40 per cent, with showers possible Friday and a slight chance returning Sunday. Saturday is expected to stay dry with a mix of sun and cloud. Daytime highs will ease back to around 25 C by Wednesday.

Residents looking to get outside to enjoy the early-week sun should do so with caution. While the temperatures may seem manageable for early June, the UV level is at a peak intensity that demands real precautions. The shift to rain by mid-week gives a clear window for outdoor plans before conditions turn.
