Climate Data Online: Provides direct access
to historical climate data for specific locations and dates.
Almanac Data: Provides average and extreme temperature and precipitation values for a particular station over its entire period of record. Where available, the most recent 5 years of daily data are displayed.
Climate Normals & Averages: Climate averages and extremes for Canadian locations with at least 15 years of data between 1971 to 2000.
Climate Summaries: A cross-country summary of averages and extremes for one month.
WMO Volume A Report - Canada: Lists all Canadian surface and upper air stations providing synoptic meteorological reports, their operational activities and essential detailed information.
IDF Files: Produced February 09, 2012. Short-duration rainfall intensity-duration-frequency (IDF) statistics in the form of tables and graphs with accompanying documentation, for 563 locations across Canada. These files can be downloaded for each province, territory, or for all of Canada.
Historical Publications: Historical Environment Canada publications now available digitally. These publications are based on studies or analyses using data from the National Climate Archives.
Historical Radar: Provides access to historical radar images for 31 stations across Canada. National, regional and local images are available.
Canadian Weather Energy and Engineering Datasets (CWEEDS): A computer dataset of hourly conditions for 21 weather elements occurring at a specific location. Datasets may begin as early as 1953 and end for most in 2005. CWEEDS files include the long term weather records necessary for urban planning and the design of energy efficient buildings. Most importantly, CWEEDS files provide the provision of estimated hourly solar radiation amounts (through the use of a model), for weather observation locations at which solar radiation is not observed.
Canadian Weather year for Energy Calculation (CWEC): Datasets created by joining twelve Typical Meteorological Months selected from a database of, usually, 30 years of CWEEDS data. The months are chosen by statistically comparing individual monthly means with long term monthly means for daily total global radiation, mean, minimum and maximum dry bulb temperature, mean, minimum and maximum dew point temperature, and mean and maximum wind speed.
Canadian Daily Climate Data (CDCD): For those with a high speed
Internet connection, the 2006/7 CDCD containing daily
temperature, precipitation and snow-on-the-ground data is available for download. Data is available for the complete period
of record for each location up to 2007. The file contains software that provides access to the data.
Please note that the CDCD download file is 212 MB and will require 880 MB of disk space when uncompressed. Download times will vary according to each user's system and internet traffic.
