The morning begins with clear skies, light but steady winds of 22 km/h, and a 20% chance of precipitation. Temperatures rise from 10°C early in the day to 19°C by noon, giving the city a steady warmup before the afternoon peak.

By afternoon, Edmonton is expected to reach 25°C under cloudy skies. Winds ease slightly to 19 km/h, while the chance of precipitation stays at 20%. For anyone planning a longer outdoor stretch, that leaves a warm window before the weather changes later in the day.

Thunderstorms by evening

The shift arrives in the evening, when thunderstorms are expected with a 40% chance of rain and about 0.4 mm of precipitation. Temperatures are forecast to cool to around 20°C, and winds should remain light at 19 km/h.

The day’s pattern leaves a narrow planning window for outdoor activity suggestions tied to the forecast, including dog walks, yoga, trail running, brunch, botanic garden activities, and an art and craft fair. The clearest reading is simple: Edmonton gets the warmest weather before dinner, then the evening turns unstable.
