Calgary is basking in a prolonged period of warm weather, with daytime temperatures expected to hover around 20 degrees Celsius until the start of the May long weekend. This pleasant stretch of mild conditions is a welcome change for residents and visitors alike, offering ample opportunity for outdoor activities.
Extended Warmth Ahead
According to Environment Canada, the city will see mostly sunny skies and temperatures consistently in the low 20s through the coming days. The warm spell is attributed to a high-pressure system that has settled over the region, blocking cooler air from moving in. Nighttime lows will also remain relatively mild, dipping to around 5 to 10 degrees Celsius.
Weekend Outlook
The trend is expected to continue into the May long weekend, though a slight cooling trend may begin by Sunday or Monday. Forecasters suggest that a weak front could bring a chance of showers by the end of the weekend, but overall conditions will remain favorable for those planning outdoor events.
Calgary's warm spell is part of a broader pattern affecting much of southern Alberta, with similar conditions reported in Lethbridge and Medicine Hat. The unseasonably warm weather has accelerated snowmelt in the Rocky Mountains, raising water levels in rivers and streams. Officials urge caution near waterways, especially for hikers and campers.
Residents are advised to take advantage of the sunny days while they last, as longer-range models indicate a potential pattern change later in May. For now, Calgary enjoys a classic spring warm-up, perfect for patio dining, cycling, and exploring the city's many parks.
