* Each location provided here corresponds to a point location in Canada. The data displayed is for the ~10 km x 6 km grid cell within which the selected location lies. Accordingly, the data does not necessarily reflect the exact point that you select, particularly in areas with varying microclimates.

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-M6) climate model datasets. 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.
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.

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.

The Future Building Design Value Summaries are location-based summaries of the building design values developed by Environment and Climate Change Canada as part of the Climate-Resilient Buildings and Core Public Infrastructure (CRBCPI) project.
The values are obtained from the Pacific Climate Impacts Consortium (PCIC)’s Design Value Explorer and are summarized into a table alongside relevant supporting guidance and information for every location in the National Building Code of Canada (NBCC, 2015).
Historical values are from the NBCC 2015, Table C-2* while the future values are derived from regional climate model simulations (CanESM2-CanRCM4) and are presented for two levels of global warming 1.5°C and 3°C above the 1986-2016 baseline period.
These summaries are tailored to users who would consult the NBCC as part of their work, for climate-related design and planning needs.

This future-looking information comes with an associated uncertainty, as fully described for each design value element in the CRBCPI.
In brief, Tier 1 variables are those for which there is generally high or very high confidence in the future projections for a given level of global warming. These variables reflect the well-understood thermal response of the climate to external radiative forcing of the Earth system.
Tier 2 variables are those for which there is generally medium confidence in the future projections for a given level of global warming.
Tier 3 variables are those for which there is low or very low confidence in the future projections for a given level of global warming.
Additional guidance on the use of the Design Value Explorer and the associated data can be found in the Learning Zone and under the ‘About’ tab in the tool on PCIC’s website.
*Historical values are derived from records prior to 2008 for most variables. At two locations (Pine Falls, MB and Boiestown, NB), historical values were provided by PCIC as these locations had problematic or missing data.
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.
