Please note that for the Engineering Climate Datasets, IDF dataset is available through this link.  Intensity-Duration-Frequency (IDF) Files: Includes the latest version of short-duration rainfall Intensity-Duration-Frequency (IDF) statistics in the form of tables and graphs with accompanying documentation for various locations across Canada.  Current IDF files can be accessed through our station finder application or downloaded for each province and territory across Canada.  In addition, historical versions of IDF files are also available for download.  Updates of IDF files are provided approximately every two years depending on the availability of data.   Thank you for your patience as we enhance our systems.

Normals Data

The minimum number of years used to calculate these Normals is indicated by a code for each element. A "+" beside an extreme date indicates that this date is the first occurrence of the extreme value. Values and dates in bold indicate all-time extremes for the location.

Data used in the calculation of these Normals may be subject to further quality assurance checks. This may result in minor changes to some values presented here.

Legend

  • A = WMO "3 and 5 rule" (i.e. no more than 3 consecutive and no more than 5 total missing for either temperature or precipitation)
  • B = At least 25 years
  • C = At least 20 years
  • D = At least 15 years
Station / Element Metadata

Statistics listed below are provided as a guide to determine the validity of Normals and Extremes calculations. For example, a station with 30 years of record between 1981 and 2010 with no missing years would be a more reliable normal than a station with 15 years of record and 2 missing years. Less than 100% possible observations indicates that out of the total number of observations used, some records were missing.
