Variable data can be measured directly in the field (e.g., at a weather station) or calculated by climate models. Here we provide access to the CMIP5 (CanDCS-U5) and CMIP6 (CanDCS-U6) climate model datasets, both of which have been downscaled and bias-adjusted using the BCCAQv2 method. To download the percentile values for any, or all, of the climate variables and indices available on ClimateData.ca, select Annual, Monthly or Seasonal frequencies. To download the daily downscaled data for minimum and maximum temperature and precipitation for each of the climate models in the CMIP5 or CMIP6 ensembles, select Daily frequency.

If the red process button is still greyed out, here are a few troubleshooting suggestions:

  • Make sure you’ve selected at least one grid cell on the map in Step 5 (typing in a location name in the search bar does not select a grid cell).
  • Make sure you have typed in a file name for your download in Step 6.
  • Make sure you are using Chrome as your browser, ClimateData.ca is optimized for Chrome.
  • Try refreshing the page.

Station Data is historical daily observed weather station data from the Meteorological Service of Canada and Environment and Climate Change Canada.  Download data by selecting stations from the drop-down list, or click one of the clusters on the map below to see which stations are available for download in that area. Click on one, or multiple stations, to select for download.

Hourly data for some stations and variables can be found on the Government of Canada Historical Climate Data website.
More station data from British Columbia can be found on the Pacific Climate Impacts Consortium website.

Intensity Duration Frequency (IDF) curves relate short-duration rainfall intensity with its frequency of occurrence. Access historical and climate change-scaled IDF data produced by Environment and Climate Change Canada either by selecting the station from the drop-down list or by clicking on one of the points on the map below.

Adjusted and Homogenized Canadian Climate Data (AHCCD) consists of weather station datasets (temperature and precipitation only) and has been developed by Environment and Climate Change Canada for use in climate research, including climate change studies. The station records in AHCCD have been adjusted using statistical techniques to detect and remove discrepancies in long-term data records caused by non-climatic factors (e.g., changes in instrumentation, observing procedures, and weather station location or site exposure). Longer time series were sometimes created by combining data from nearby stations. Click on one of the clusters below to download AHCCD available for that region.

Climate Normals describe the average climate conditions of a particular location over a 30-year period.

At the end of each decade, Environment and Climate Change Canada calculates a new set of climate normals using station observations from that decade. All member countries of the World Meteorological Organisation calculate climate normals. As they describe the most recent average climate conditions for a location, they are often used to put extreme events into context.

The climate normals offered here are based on Canadian climate stations with at least 15 years of data available during the current 30-year normal period.
