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.

  • Eight-Day Accumulated Precipitation Map (PDF 2 MB)  (May 16 - 23, 2022)  shows that precipitation across agro-Manitoba ranged from 0.6 mm to 71 mm in the past eight days at our weather station locations.  Lakeland (71 mm), Elie (61 mm), and Starbuck (60.6 mm) were the top three locations with the highest precipitation. Most areas received at 30 mm.
  • Total Accumulated Precipitation (PDF 2 MB) (May 01 - 23, 2022) shows the total precipitation amount since May 1. Eden (123) reported the highest total accumulated precipitation since May 1, 2022, followed by Ethelbert (118 mm) and McCreary (115 mm).  The Interlake and Central regions close to the International border have received between 40 to 60 mm since May 1.
  • Percent of Normal Accumulated Precipitation (PDF 2 MB) (May 01 - 23, 2022) is based on historical record over a 30-year period. Almost the entire agro-Manitoba have received at least 150% of normal precipitation with many areas receiving close to three times the normal amount of precipitation.  McAuley (307%), Ethelbert (288%), and Eden (277%) are the top three locations with the highest percent of normal precipitation. The areas south of Somerset in the Central region have received close to normal precipitation.
  • Top 0-30cm Soil Moisture (PDF 621 KB) (May 23, 2022) shows a regional representation of soil moisture conditions for the top 30 cm on May 23, 2022 relative to field capacity.  Almost all areas monitored showed wet to very wet conditions at the top 30 cm. Several areas around Lake Manitoba and the Whiteshell areas in the Eastern region are showing very wet conditions.
  • Top 0-120cm Soil Moisture (PDF 617 KB) (May 23, 2022) shows a regional representation of soil moisture conditions for the top 120 cm on May 23, 2022 relative to field capacity. Similar to the 0-30 cm soil moisture condition, almost all areas monitored showed wet to very wet conditions at the top 120 cm. The Whiteshell, Turtle Mountain and areas around Lake Manitoba showed very wet conditions.
  • Total Accumulated Growing Degree Days (PDF 2 MB) (May 01 - 23, 2022) The maximum total GDD accumulation was observed at both St. Adolphe and Steinbach with 128 unit.  Areas around the Red River have accumulated at least 115 heat units but areas around Lake Audy at the Riding Mountain have accumulated less than 75 units.
  • Percent Normal Accumulated Growing Degree Days  (PDF 2 MB) (May 01 - 23, 2022) represents the variation of accumulated Growing Degree Days (GDD) from the historical record over a 30-year period.  All of agro-Manitoba has accumulated below normal GDD so far this season. Inwood (96%), Arborg (93%) and Eriksdale (93%) have accumulated the highest GDD compared to the historical average. Most areas in the southwest and northwest regions have accumulated less than 75% of historical average GDD.
  • Total Accumulated Corn Heat Units (PDF 2 MB) (May 01 - 23, 2022) illustrates the total accumulated Corn Heat Units (CHU) for the growing season to date. Wasagaming has accumulated the lowest total accumulated CHU with 103 units. Areas near Winkler (226), Steinbach (222), and Gardenton (219) accumulated the most CHU since May 1.
  • Percent Normal Accumulated Corn Heat Units (PDF 2 MB) (May 01 - 23, 2022) represents the variation of accumulated corn heat units (CHU) from the historical record over a 30-year period. Most of the eastern region has accumulated at least 80% of the historical accumulated CHU. Most areas in the western half of agro-Manitoba has accumulated less than 75%.  Inwood has accumulated the highest percent normal accumulated CHU at 89% compared to the 30-year average.
