Chinook Winds Bring Record March Temperatures to Calgary as Spring Arrives Early
Environment Canada confirms 23°C reading at Calgary International Airport, breaking a 78-year-old record.
A powerful Chinook system pushed temperatures in Calgary to 23°C on Wednesday, shattering the previous March 11 record of 19.4°C set in 1948, according to Environment Canada.
The warm, dry winds that swept down from the Rocky Mountains brought summer-like conditions to much of southern Alberta, with Lethbridge reaching 25°C and Medicine Hat hitting 26°C — both also daily records.
Calgarians Embrace the Warmth
Parks, pathways, and patios across the city were packed as residents took advantage of the unexpected spring preview. The Bow River pathway saw what Parks officials described as “summer-level” foot traffic.
“I’ve lived here 40 years and I don’t remember anything like this in March,” said Stephen Avenue pedestrian George Lawson. “You take what Calgary gives you and you enjoy it.”
Climate Context
Environment Canada meteorologist Natasha Fehr said while Chinook events are normal for the region, the intensity of this system is “noteworthy.”
“Chinooks are part of Calgary’s climate identity, but we are seeing a trend toward more extreme temperature swings during these events,” Fehr said. “This is consistent with what climate models project for the region.”
Temperatures are expected to return to seasonal norms by the weekend, with a chance of snow by Sunday.
Watch for Rapid Melt
The City of Calgary has issued an advisory about potential flooding in low-lying areas as the warm temperatures accelerate snowmelt. Residents are encouraged to clear storm drains near their properties and report any flooding concerns to 311.
Emergency Management Calgary says crews are on standby in historically flood-prone areas, though the current risk is assessed as low.
