Barrhead, Alberta is in for a stretch of warm, sunny weather this week as Environment Canada forecasts temperatures well above normal for late September. The high on Monday, September 21, is expected to reach 25°C, a full 10 degrees above the seasonal normal of 15°C.
The warm spell continues Tuesday with mainly sunny skies and a high of 20°C. Overnight lows will be cool, ranging from 5°C to 7°C through mid-week under partly cloudy to cloudy skies, making for pleasant evenings despite the warmer days.
Residents can expect ideal conditions for outdoor activities, yard work, or simply enjoying the late-season sunshine. The UV index is forecast at 4 on Monday and 3 on Tuesday, both considered moderate, so standard sun protection is advised during peak hours.
The warm trend is part of a broader pattern noted by The Weather Network, which predicts above-seasonal temperatures across much of Canada east of the Rocky Mountains this September. Historical averages for Barrhead in September show typical highs of 18°C and lows of 5°C, making this week noticeably warmer than usual.
However, the summer-like conditions won’t last. Environment Canada forecasts a cooling trend beginning Wednesday, with a mix of sun and cloud and a high of 17°C. There is a 30 percent chance of showers Wednesday night, and by Friday, September 25, the chance of showers increases to 60 percent Friday night with a low of 4°C. Residents are encouraged to take advantage of the warm, dry days early in the week before the shift to more typical autumn weather.
