Station data over Canada

Environment Canada (EC) maintains a collection of over 200 million observations, from over 7,000 sites, some dating as far back as 1840. These records of Canada's ever-changing weather have proved invaluable to a wide variety of specialists, including weather forecasters, emergency planners and weather-dependent businesses and industry.

The National Climate Data and Information Archive, operated and maintained by EC, includes official climate and weather observations for Canada. The database contains monthly, daily and hourly weather observations, including temperature, precipitation, air pressure, wind speed, and cloud types, as well as notes on the occurrence of thunderstorms, hail, fog and other types of weather. You can find more information on the National Climate Data and Information Archive website.
