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)  (June 20- June 26, 2022)  shows that precipitation across agro-Manitoba ranged from 6 mm to 99 mm in the past seven days at our weather station locations.  Taylor’s Point (99.8 mm), McCreary (99.4 mm), and Fisherton (90 mm) were the top three locations with the highest amount of precipitation last week. Most of the precipitation occurred on Tuesday, June 21 around the Interlake and Northwest regions, with more precipitation over the weekend. Areas around Birtle, Oakburn and Russell had intense storm activity on Friday. The southwest region around Pierson and Melita had the least amount of precipitation, less than 10 mm.
  • Total Accumulated Precipitation (PDF 2 MB) (May 01- June 26, 2022) shows the total precipitation amount since May 1. McCreary, Alonsa and Forrest have reported the highest total accumulated precipitation at 358.8 mm, 309.9 mm and 307.2 mm, respectively. The Interlake and the areas east of Riding Mountain National Park, as well as areas around Winnipeg have received between 220 – 300 mm. Many areas in the central region, south of Treherne have mostly received 140 – 180 mm.
  • Percent of Normal Accumulated Precipitation (PDF 2 MB) (May 01 - June 26, 2022)  is based on historical record over a 30-year period. Most areas of agro-Manitoba have received at least 150% of normal precipitation with some areas receiving more than two times the normal amount of precipitation. The exceptions are areas close to the International border. McCreary (275%), Forrest (270%), and Alonsa (269%) are the top three locations with the highest percent of normal precipitation. These areas have received more than twice the historical amount of precipitation for the months of May and June.
  • Top 0-30cm Soil Moisture (PDF 621 KB) (June 26, 2022) shows a regional representation of soil moisture conditions for the top 30 cm on June 26, 2022 relative to field capacity.  Locations in the Interlake and east of Riding Mountain, as well as areas around St. Lazare, Oakburn and Russell have very wet surface soil moisture due to the amount of recent precipitation at those areas. Almost all areas monitored showed optimal to wet conditions at the top 30 cm. Some areas in the central region (Elm Creek, Carman, Elie etc) and southwest (Pierson and Waskada) are showing optimal to dry surface soil moisture.
  • Top 0-120cm Soil Moisture (PDF 623 KB) (June 26, 2022) shows a regional representation of soil moisture conditions for the top 120 cm on June 26, 2022 relative to field capacity. Most areas monitored showed wet conditions at the top 120 cm. The areas around Lake Manitoba and the Whiteshell areas around Elma and Prawda show a very wet soil moisture condition at the entire soil profile.
  • Total Accumulated Growing Degree Days (PDF 2 MB) (May 01- June 26, 2022) shows the accumulated growing degree days (GDD) for the period of May 01 – June 26, 2022.  The highest total GDD accumulation was observed at Winkler with 567 units.  Areas from Bagot in the central region to Beausejour in the eastern region and south to the International border have accumulated at least 490 heat units. However, most areas in the northwest region have accumulated less than 430 units.
  • Percent Normal Accumulated Growing Degree Days  (PDF 2 MB) (May 01- June 26, 2022) represents the variation of accumulated Growing Degree Days (GDD) from the historical record over a 30-year period.  Several days with above normal air temperature resulted in increased heat unit accumulation. Only 10% of the locations monitored (mostly in the eastern and Interlake regions) have accumulated above normal growing degree days. Most areas have accumulated between 85 – 90% in the northwest region; 90 - 95% of normal in the southwest region; and 95 – 100 in the eastern region. The highest percent of normal accumulated GDD is at Steinbach (105% of normal).
  • Total Accumulated Corn Heat Units (PDF 2 MB) (May 01- June 26, 2022) illustrates the total accumulated Corn Heat Units (CHU) for the growing season to date. The northwest region has mostly accumulated less than 720 CHU. Areas near Winkler (929), Morden (912) and Gretna (910) have accumulated the most CHU since May 1.
  • Percent Normal Accumulated Corn Heat Units (PDF 2 MB) (May 01- June 26, 2022) represents the variation of accumulated corn heat units (CHU) from the historical record over a 30-year period. Most areas in the eastern half of agro-Manitoba have accumulated 95-100% of the historical accumulated CHU. The northwest region has mostly accumulated 85 - 90% of historical CHU.  Steinbach has accumulated the highest percent normal accumulated CHU at 104% compared to the 30-year average.
  • Total Accumulated P-Days (PDF 2 MB) (June 06 – June 26, 2022) represents the total accumulated physiological days for potatoes (P-days) since June 6, 2022.  P-days accumulation has a different start date (June 6) because accumulation commences at about 50% potato emergence. Other heat accumulations start from May 1. Lakeland and Clarkleigh (171) have accumulated the highest P-days. 
  • Percent of Normal Accumulated P-Days (PDF 2 MB) (June 06 – June 26, 2022) represents the variation of accumulated physiological days for potatoes (P-days) from the historical record over a 30-year period.  Much of agro-Manitoba has accumulated above historical average P-Days since June 6. The major potato growing areas in the southwest and central regions have received 100 – 115% of normal p-days
