Guelph, Ontario is in for a week of mixed weather, starting with a chance of showers and a risk of thunderstorms before skies clear up for a sunny Saturday, according to Environment Canada. No weather alerts are currently in effect, but residents should keep rain gear handy, especially on Thursday, June 25, when the chance of precipitation is highest.
Monday afternoon brings a 30 percent chance of showers, with clearing expected later in the day and a high of 21°C. Tuesday looks brighter with sunny skies and a high of 24°C, while Wednesday warms up to 25°C. However, Thursday is the day to watch, as forecasters call for cloudy conditions with a 60 percent chance of showers or thunderstorms and a high of 22°C. The Weather Network notes an even higher risk of thunderstorms, with precipitation probabilities reaching 70 to 80 percent and rainfall amounts of 2 to 4 millimetres during the afternoon and about 5 millimetres in the evening.
The UV index will be 8, or very high, on Monday and Tuesday, meaning extra sun protection is a must. Health Canada and Environment Canada recommend seeking shade between 11 a.m. and 3 p.m. and using sunscreen, hats, and sunglasses. Even on days with cloud cover, the UV can still be strong this time of year.
Temperatures will gradually recover after Thursday, with highs of 24°C on Friday and Saturday and 26°C on Sunday. The weekend is expected to be the most pleasant stretch, with a mix of sun and cloud and no rain in the forecast. The normal high for late June in Guelph is 25°C, so much of the week will be right around or slightly below the seasonal mark.
As of early afternoon Monday, the temperature at the Guelph Turfgrass Institute observation station was 16.7°C with 76 percent humidity and a light northeast wind at 5 km/h. With the summer solstice just past, daylight hours are near their peak, giving residents plenty of time to enjoy the improving weather as the weekend approaches.
