Almonte, Ontario, is in for a mix of weather to start June, with a chance of thunderstorms Monday afternoon before a quick warm-up brings summer heat by midweek.
Environment Canada calls for a high of 21°C on Monday, June 1, with a 40 percent chance of showers and a risk of a thunderstorm late this afternoon. East winds will be around 20 km/h, easing as the day goes on. The UV index is rated 6, or high, so sun protection is still a good idea.
Monday night stays partly cloudy with a 40 percent chance of showers early in the evening and another thunderstorm risk before skies clear overnight. The temperature will drop to a low of 7°C.
The cool start is a short one. Temperatures climb steadily through the week: Tuesday reaches 23°C, Wednesday jumps to 29°C, and Thursday peaks at a summer-like 30°C. The weekend settles in with 24°C on Friday, 25°C on Saturday, and 27°C on Sunday under mainly sunny skies.
There is good news for anyone worried about spring flooding. The Mississippi Valley Conservation Authority reports the Mississippi River watershed has been back to normal since May 12, 2026, meaning no flood conditions exist. A flood watch had been issued on April 15, 2026, after heavy rain and melting snow pushed water levels up, but conditions have since improved.
Residents heading outdoors today should watch for changing skies and maybe pack a light jacket, but they can look forward to much warmer and sunnier days ahead.
