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)  (March 13 - 19, 2023)  
    Precipitation from March 13 – 19 ranged from 0 to 4.5 mm (Table 1). The Northwest and Interlake received little to no precipitation. 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.

    Climate normals for total accumulated precipitation from November 1 to March 19 range from 66.7 to 119.5 mm (Tab. 2), and are based on 30-year historical data. Save for a few locations in the Northwestern region, much of the province has accumulated precipitation below 50% of normal for this time period.

Average Temperature Deviation from Normal

Average temperature deviations from normal for the week range from -2.3 to 1.8 ℃ (Tab. 3), and are based in 30-year historical data. The majority of agro-Manitoba in the East and Interlake show temperature deviations to date have been normal to slightly above normal for the season. Parts of the Northwest and Southwest were slightly below normal.
