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 476 KB)  (June 07 - 13, 2021)  shows that precipitation across agro-Manitoba ranged from 7 mm to 116 mm in the past seven days at our weather station locations after several rain events this past week.  St. Lazare (116 mm), Manitou (113 mm), and Snowflake (110 mm) were the top three locations with the highest precipitation.  The lowest precipitation amounts were observed in the East region of agro-Manitoba in the areas of Menisino (7 mm) and Prawda (7 mm).
  • Total Accumulated Precipitation Map (PDF 800 KB) June 07 - 13, 2021)  shows the total precipitation amount since May 1.  Ninette (165 mm) reported the highest total accumulated precipitation since May 1, 2021, followed by St. Lazare (152 mm) and Manitou (144 mm).  A small area of the northern Interlake has accumulated less than 60 mm of precipitation since May 1.
  • Percent of Normal Accumulated Precipitation (PDF 796 KB) (June 07 - 13, 2021)  is based on historical record over a 30-year period. St. Lazare (200%), Newdale (185%), and McAuley (184%) are the top three locations with the highest percent of normal precipitation.  Most of agro-Manitoba has accumulated more than 80% of normal precipitation compared to the 30-year average.
  • Soil Moisture 0-30cm (PDF 791 KB) (June 13, 2021)  shows a regional representation of soil moisture conditions for the top 30 cm on June 13, 2021 relative to saturation.  Menisino, Moosehorn, Poplarfield, Inwood, and Gardenton were indicating dry top soil moisture conditions on June 13. A large are of the Northwest and part of the Central regions are indicating wet conditions.
  • Soil Moisture 0-120cm (PDF 792 KB) (June 07, 2021) shows a regional representation of soil moisture conditions for the top 120 cm on June 13, 2021 relative to saturation. Areas around of the Northwest and portions of Central and Eastern agro-Manitoba are indicating wet to very wet soil moisture conditions at the 0-120 cm depth. Areas near Pierson, Eden, Gladstone, Menisino, and parts of the Interlake are indicating 20-40% soil moisture relative to saturation.
  • Total Accumulation of Growing Degree Days (PDF 471 KB) (June 07 - 13, 2021) shows the accumulated growing degree days (GDD) for the period of May 01 – June 13, 2021.  The maximum total GDD accumulation was observed at Morden (430), Winkler (430), and Emerson (418). Most of the southern portion of agro-Manitoba has accumulated more than 330 GDD.
  • Percent Normal Accumulated Growing Degree Days (PDF 484 KB) (June 07 - 13, 2021)   represents the variation of accumulated Growing Degree Days (GDD) from the historical record over a 30-year period.  Much of the East and Interlake have accumulated more than 100% of normal GDD so far this season. Arborg (118%), Sprague (117%), and Menisino (116%) have accumulated the highest GDD compared to the historical average.
  • Total Accumulated Corn Heat Units (PDF 792 KB) (June 07 - 13, 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 444. Areas near Winkler (702), Emerson (694), and Gretna (690) accumulated the most CHU since May 1.
  • Percent Normal Accumulated Corn Heat Units (PDF 478 KB) (June 07 - 13, 2021) represents the variation of accumulated corn heat units (CHU) from the historical record over a 30-year period. Much of agro-Manitoba has accumulated more than 100% of the historical accumulated CHU. Oakburn has accumulated the lowest percent normal accumulated CHU at 88%.  Inwood has accumulated the highest percent normal accumulated CHU at 119% compared to the 30-year average.
  • Total Accumulated P-Days (PDF 795 KB) (June 1 - 13, 2021)  represents the total accumulated physiological days for potatoes (P-days) since June 1, 2020.  P-days accumulation has a different start date (June 1) because accumulation commences at about 50% potato emergence. Other heat accumulation starts from May 1. The majority of agro-Manitoba has accumulated more than 95 P-days since June 1. Much of the East, Interlake, and Central areas have accumulated more than 100 P-days with Rosa (106) and Steinbach (106) accumulating the highest P-days.  Birtle (85 P-days) has the lowest P-Day accumulation.
  • Percent of Normal  Accumulated P-Days (PDF 799 KB) (June 01 - 13, 2021) represents the variation of accumulated physiological days for potatoes (P-days) from the historical record over a 30-year period.  Areas of the Northwest, Interlake, and East regions have accumulated more than 120% of the normal accumulation of P-Days. The Pas (136%), Ericksdale (133%), and Minnedosa (132%) have the highest percent normal accumulation of P-days. Waskada (104%) and Bede (105%) have the lowest percent normal accumulation of P-days.
