Weather Conditions and Reports

Manitoba's ag weather program measures and records data year round from over 100 weather stations across agro-Manitoba. The stations monitor air temperature, relative humidity, barometric pressure, precipitation, wind speed and direction, solar radiation, soil temperature, and soil moisture. The latest weather conditions from each station are made available every 15 minutes throughout the growing season and every hour during the winter months.

  • Seven-Day Accumulated Precipitation Map (PDF 2 MB)  (November 21 -27, 2022)  
    Precipitation was measured all Manitoba Ag Weather Program stations, and ranged from 0.0 to 8.2 mm (Table 1).  Precipitation was relatively sparse across all regions in the province.  The Ag Weather Program measures precipitation in the off-season in terms of snow-water equivalent (SWE).  As a rule of thumb, 10 mm of precipitation SWE is equal to 10 cm of snowfall.

  • Total Accumulated Precipitation (PDF 2 MB) (November 01 - 27, 2022) 
  • Percent of Normal Accumulated Precipitation (PDF 2 MB) (November 01 - 27, 2022)  
    Climate normals for total accumulated precipitation for the 47th week of the year range from 11.4 to 32.1 mm (Tab. 2), and are based in 30-year historical data.  Save for a few locations in the Northwestern region, much of the province lags behind normals for this week in the year, with many locations in the Central, Eastern, Interlake, and Southwest regions at less than 50% of normal

Average temperature deviations from normal for the 47th week of the year range from -2.7 to +1.9 ℃ (Tab. 3), and are based in 30-year historical data.  Much of the Central, Eastern, and Interlake regions were slightly above normal, whereas many locations in the Northwest and Southwest regions were slightly below normal.Table 3.
