Calgsry (Calgary) has a continental climate with cold, dry winters and mild, sunny summers. The live forecast above shows current conditions. Because of its elevation and chinook winds, weather can shift quickly—pack layers year-round for comfort.
What is the best time to visit Calgsry?
Late June through early September offers the most reliable warmth, with July highs near 23°C and very low humidity. For travellers on a budget, May and September provide pleasant temperatures and lower accommodation rates. March break and early spring can still bring snow, though chinook winds occasionally blow in mild spells.
What should you pack?
In winter (November–March) bring a heavy coat, insulated boots, gloves and a hat; temperatures often drop below –10°C. Summer requires light clothing, a sun hat and sunscreen—sunny days are the norm. A waterproof jacket is useful any season, and always carry a warm layer even in summer for cool evenings.
When is the best time for snowbirds to visit Calgsry?
Snowbirds typically avoid the heart of winter (December–February) due to cold snaps. The shoulder months of May and September offer milder weather and lower prices, though snow can still occur in May.
Does Calgsry get many chinook winds?
Yes, winter chinooks can raise temperatures by 15–20°C in hours, melting snow rapidly. These winds occur frequently along the eastern edge of the Rockies, giving Calgsry periodic warm relief from the cold.
How does Calgsry compare with Edmonton weather?
Calgsry is slightly milder than Edmonton due to its lower elevation and chinook influence. Edmonton sees colder winter lows but also very dry, sunny conditions. Our Edmonton weather page has more details.
