Notices:
As of Dec. 15, 2011 the OTTAWA MACDONALD-CARTIER INT’L A and HAMILTON A weather reporting stations have switched over to new NAV CANADA sensors and reporting tools. Due to a new format, hourly data from these stations is not yet available on our website. If you are interested in daily data for these stations from Dec 15, 2011 forward, they can now be found under their new weather station names, OTTAWA INT’L and HAMILTON. For more information, please click here. Thank you for your patience while we work to upgrade our system to display these data.
We are currently experiencing some problems with the French version of the Climate Summaries on our Products & Services page. We are working to rectify the problem and ask for your patience during this time of technical difficulty. In the meantime, please refer to the data available from the English Climate Summaries page.
The Notice Inventory contains a record of all past and current Notices.
Canadian Climate Normals or Averages 1971-2000
Climate normals or averages are used to summarize or describe the average climatic conditions of a particular
location.
At the completion of each decade, Environment Canada updates its climate normals for as many locations and as many climatic
characteristics as possible. The climate normals and extremes offered here are based on Canadian climate stations with at least
15 years of data between 1971 to 2000.
