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.

Precipitation

Eight-Day Accumulated Precipitation  (PDF 2 MB)

Eight-Day Accumulated Precipitation (October 6 - 13)
Precipitation and strong winds over 60 km/hr were observed in the Eastern and Interlake regions as well as  in parts of the Northwest and Central regions on October 13. Snow accumulated in parts of the Northwest.  Accumulations this week ranged from 0 mm to 65.7 mm (Table 1). The highest amount of rainfall was observed in the Eastern and Northwest regions with The Pas accumulating 65.7 mm. Much of the Southwest region received little to no precipitation over the past eight days.

Percent Normal Precipitation (PDF 1 MB)

Total Accumulated Precipitation (PDF 2 MB)

Climate normals for total accumulated precipitation from May 1 to October 13 range from 271.0 mm to 424.3 mm (Table 2) and are based on 30-year historical data. Large areas of the Central, Eastern, and Northwest regions have accumulated more than 220 mm of precipitation this growing season. Total precipitation accumulations this season remain below 60% compared to the 30-year average in the Interlake and parts of the Northwest. Parts of the Southwest and Central regions have accumulated more than 100% of normal precipitation levels since May 1.

Soil Moisture

Soil Moisture 120cm (1 MB)

  1. Soil Moisture 0 - 30 cm shows a regional representation of soil moisture conditions for the top 30 cm on October 13, 2025 relative to field capacity. Soil moisture is variable across agro-Manitoba with areas within the same regions showing very dry to very wet conditions. Areas of the Interlake continue to show dry conditions while other areas are showing optimal or wet conditions. Due to recent precipitation, wet conditions were prevalent in the Southwest, Central, Eastern, and Northwest regions on October 13.
  2. Soil Moisture 0 - 120 cm shows a regional representation of soil moisture conditions for the top 120 cm on October 13, 2025 relative to field capacity. Areas of the Interlake are showing dry or very dry conditions, while the majority of the region is showing optimal conditions. Most of the remaining regions are showing wet or optimal conditions at the 0 to 120 cm depth with some localized areas showing very wet or very dry conditions.

  1. Total Accumulation of Growing Degree Days shows the accumulated growing degree days (GDD) for the period of May 1 – October 13, 2025. Much of the Central and Eastern regions have accumulated more than 1850 GDD since May 1.
  2. Percent Normal Accumulated Growing Degree Days represents the variation of accumulated Growing Degree Days (GDD) from the historical record over a 30-year period from May 1 – October 13, 2025. GDD Accumulations are between 105% and 115% of normal for the majority of agro-Manitoba.

Percent Normal Accumulation Corn Heat Units (2 MB)

  1. Total Accumulated Corn Heat Units illustrates the total accumulated Corn Heat Units (CHU) for the growing season to from May 1 – October 13. Above normal temperatures this past week led to continued accumulation of CHU. More than 2850 CHU have accumulated in most of the Southwest, Interlake, Central, and Eastern regions since May 1.
  2. Percent Normal Accumulated Corn Heat Units represents the variation of accumulated Corn Heat Units (CHU) from the historical record over a 30-year period for the period of May 1 – October 13. CHU accumulations are between 105% and 120% of normal for most regions.

P-Days

Percent Normal P-Days (2 MB)

Total Accumulated P-Days (2 MB)

  1. Total Accumulated P-Days (June 1 – October 13) represents the total accumulated physiological days for potatoes (P-days) since June 1. As P-Day accumulation begins at about 50% potato emergence, accumulation begins on June 1. The southern regions of agro-Manitoba have accumulated more than 940 P-Days this season.
  2. Percent of Normal Accumulated P-Days (June 1 – October 13) represents the variation of accumulated physiological days for potatoes (P-days) from the historical record over a 30-year period. The majority of agro-Manitoba has accumulated over 105% of normal P-Days so far this season.
