Notices:

As of November 19 2009, changes have been made to how Wind Chill and Humidex values are calculated. A detailed outline of these calculations can be found in the Glossary.

We are pleased to announce the release of a new feature, Historical Radar to our site.  The Historical Radar feature allows users to view historical radar images from 2007 to present at the national, regional and local levels.  It can be accessed by clicking the “Historical Radar” link on the left menu bar.

As of July 24 2008, changes were made in how data are accessed at 25 stations. Please click here for further details.

The Notice Inventory contains a record of all past and current Notices.

Canadian Climate Normals 1971-2000

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.

NOTE!! 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.
