Notices:

Several airport weather reporting stations have switched over to new NAV Canada sensors and reporting tools. Please click here and expand the message for the list of new NAV Canada stations with the latest data:

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

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 1971 and 2000 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.
