What’s New in latest Release from January 14th 2021:

·       In Historical Hourly Data Report, users can switch between Local Standard Time (LST) and Universal Time Coordinates (UTC) time.

·       In Historical Hourly Data Report, we have an addition of a new column to display hourly precipitation data for the stations where the data are available, from 2001 onwards.

·       Expanded the Search Options of the Canadian Historical Weather Radar, users now able to select 24 hours (1 image every hour) image viewing duration.

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.
