Overview
Knowing about past weather patterns can be more important than a weather forecast.
On a specific date in Alberta, did it snow or freeze? How cold or warm was it? How much did it rain? Was it humid or windy? Using the information and tools in this section, you can access this and additional information, looking back by the hour, day, week, month or year.
Historic climate information is also important to know. For example, how hot or cold can it get, and how often? What are the seasonal rainfall patterns in an area? How much rain can fall in an extreme wet spell or drought? How much snow can fall on average, or in a heavy snow fall year? What are the average growing degree days or corn heat units? Or how do recent climate conditions compare to long-term averages?
The answers to all these questions, along with weather forecasts, can be accessed by using the following weather and climate resources.
Weather and climate
Alberta Climate Information Service (ACIS)
- This website – available in desktop and mobile views – offers a set of interactive, map-based online tools. Producers, farm consultants and researchers can view Alberta weather forecasts, browse over 25,000 maps of Alberta weather and climate-related information, and access near real-time data from over 450 meteorological stations operating in the province. Maps and weather data describe Alberta's weather, climate and related agriculture features to help with your long-term planning and decision-making throughout the growing season.
