Summerside, PEI, is in the middle of a warm and humid stretch of weather with temperatures above the July average and no alerts in effect, according to Environment Canada.
Monday, July 13, 2026, hit 26°C and a humidex of 29 with gusty south-southwest winds reaching 51 km/h. Tuesday will be the warmest day of the week, with a high of 27°C and a humidex of 30, though it will be cooler along parts of the coast where the high will be near 20°C.
Showers are expected to end Tuesday morning before skies clear. The wind will be southwest at 20 km/h, gusting to 40. After that, the forecast becomes less settled.
Wednesday has a 60 percent chance of showers, with a daytime high of 24°C. Thursday will be a mix of sun and cloud, also with a high of 24°C. Thursday night will stay cloudy with a 60 percent chance of showers.
The weather this week lines up with seasonal predictions that summer 2026 would be warm and humid but not as hot as 2025. Warmer overnight lows are expected because of the higher humidity. July in Summerside typically sees average highs of 23°C and lows of 14°C, so this week’s temperatures are running a few degrees above normal.
Residents and visitors hoping to enjoy outdoor activities will see the best conditions early in the week. Monday and Tuesday offer the sunniest skies, though Monday’s wind could be a factor. The rest of the week looks more unsettled with the chance of showers sticking around into Thursday night.
