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 800 KB)  (May 10 - May 16, 2021) shows that precipitation across agro-Manitoba ranged from 0 mm to 15 mm in the past seven days at our weather station locations.  Gardenton (15 mm), Elma (10 mm), and Waskada (10 mm) were the top three locations with the highest precipitation. The majority of agro-Manitoba received less than 4 mm of precipitation in the last week.
  • Total Accumulated Precipitation Map (PDF 792 KB) (May 01- May 16, 2021) shows the total precipitation amount since May 1.  Birch River (28 mm) reported the highest total accumulated precipitation since May 1, 2021, followed by Gardenton (20 mm) and Sprague (15 mm).  A large area of the southern region and an area of the far Northwest have accumulated more than 4 mm.
  • Percent of Normal Accumulated Precipitation (PDF 789 KB) (May 01 - May 16, 2021) is based on historical record over a 30-year period. Birch River (119%), Gardenton (84%), and Minitonas (59%) are the top three locations with the highest percent of normal precipitation.  Most of agro-Manitoba has accumulated less than 50% of normal precipitation compared to the 30-year average.
  • Soil Moisture 0-30cm (PDF 788 KB) (May 16, 2021) shows a regional representation of soil moisture conditions for the top 30 cm on May 16, 2021 relative to saturation.  Several areas including Marchand and Pierson are currently indicating very dry top soil moisture conditions. Areas near Oakburn, Laurier, San Clara, Reedy Creek, and Lac Du Bonnet are showing wet conditions.
  • Soil Moisture 0-120cm (PDF 789 KB) (May 16, 2021) shows a regional representation of soil moisture conditions for the top 120 cm on May 16, 2021 relative to saturation. Areas around Fork River, Rorketon, Ste. Rose, Laurier, Reedy Creek, Oakburn, Lac Du Bonnet, and Elma are indicating wet to very wet soil moisture conditions at the 0-120 cm depth. Areas near Birch River, Forrest, Pierson, and Menisino are indicating 0-40% soil moisture relative to saturation.
  • Total Accumulation of Growing Degree Days (PDF 804 KB) (May 01 - 16, 2021) shows the accumulated growing degree days (GDD) for the period of May 01 – May 16, 2021.  The maximum total GDD accumulation was observed at Morden (82), and Deloraine (75).  Most of the East and Southwest has accumulated more than 55 GDD.
  • Percent Normal Accumulated Growing Degree Days (PDF 801 KB) (May 01 - 16, 2021) represents the variation of accumulated Growing Degree Days (GDD) from the historical record over a 30-year period.  Much of agro-Manitoba has accumulated more than 70% of normal GDD so far this season. Inwood (106%) and Keld (93%) have accumulated the highest GDD compared to the historical average.
  • Total Accumulated Corn Heat Units (PDF 792 KB) (May 01 - 16, 2021) illustrates the total accumulated Corn Heat Units (CHU) for the growing season to date. The Pas has accumulated the lowest total accumulated CHU with 84. Areas near Winkler (170), Emerson (163), and Melita (163) accumulated the most CHU since May 1.
  • Percent Normal Accumulated Corn Heat Units (PDF 797 KB) (May 01 - 16, 2021) represents the variation of accumulated corn heat units (CHU) from the historical record over a 30-year period. Most of agro-Manitoba has accumulated more than 80% of the historical accumulated CHU. Manitou has accumulated the lowest percent normal accumulated CHU at 74%.  Inwood has accumulated the highest percent normal accumulated CHU at 136% compared to the 30-year average.
