Calgarians should prepare for a blustery but relatively mild day on Thursday, December 4, 2025, before a sharp return to colder conditions. The afternoon will see winds intensify across the city, though they will arrive from the west, helping to push temperatures to a high of at least 4 degrees Celsius.
A Temporary Reprieve from the Cold
The gusty conditions on Thursday afternoon will be the main weather story, bringing a noticeable change to the city's atmosphere. Meteorologists note that the origin of these winds is a key factor in the day's brief warmth. The westerly flow is ushering in a pocket of milder air, offering a short-lived break from the typical December chill. Residents can expect the mercury to climb to a high near 4°C during this period.
The Return of Winter's Bite on Friday
This milder interlude will be fleeting. Forecast models indicate a pronounced shift as Thursday gives way to Friday. A cold front is expected to sweep through the region, causing temperatures to dip significantly. The precise low for Friday morning is still being fine-tuned, but the trend points toward a return to seasonal or below-seasonal norms, reminding everyone that winter is firmly in control.
Context and Broader Weather Patterns
This pattern of fluctuating temperatures is not uncommon for Calgary in early December, as competing air masses battle for dominance over the province. The quick transition from a windy, mild afternoon to a colder Friday serves as a reminder for locals to stay updated on the latest forecasts. Ensuring vehicles are prepared for changing conditions and having appropriate winter attire on hand is advised as the region navigates the volatile start to the meteorological winter season.
For those planning outdoor activities, Thursday afternoon may provide the better window, despite the wind, before the colder air settles in for the end of the week.
