Climate and geography

Alberta’s climate and geography are as diverse as Alberta’s people.  

Climate

Alberta has four distinct seasons, from mild summers to snowy winters. Environment Canada ranks Alberta first for having the most comfortable overall weather in Canada.

In summer, daytime highs:

  • normally range from 20 to 25 C (68 to 77 F)
  • can reach the mid to upper 30s

The driest and coldest winter months are January and February, when

  • normal low nighttime temperatures range from -15 to -25 C (5 to -13 F)
  • daytime temperatures range from -5 to -15 C (23 to 5 F)

Winter temperatures can drop as low as -30 to -40 C (-22 to -40 F) for short periods of time.

Alberta enjoys the highest number of sunny days in Canada — more than 2,300 hours of sunshine each year. Even in winter, the sky is often clear as the sun shines brightly on the sparkling snow. In June, daylight hours can reach 16 to 18 hours per day.

Geography

Alberta is the fourth largest province in Canada, covering an area of 661,000 square kilometres (255,000 square miles) — about the same size as the American state of Texas and twice the size of Japan.

Our landscapes vary from the majesty of the Rocky Mountains to the lush boreal forest that covers almost half the province, from fertile prairies to desert badlands. Alberta is also home to more than 600 lakes, 245 rivers and rich mineral resource deposits. You can learn about Alberta's natural heritage at more than 500 sites covering 27,525 square kilometres in Alberta parks protected for future generations.
