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.

Percent Normal Precipitation (PDF 2 MB)

Percent Total Precipitation (PDF 2 MB)

Climate normals for total accumulated precipitation from May 1 to June 29 range from 116.4 mm to 184 mm (Table 2) and are based on 30-year historical data. The East and Interlake regions have large areas of accumulations below 50% of normal. The majority of the Central, Northwest, and Southwest regions have accumulated less than 70% of the 30-year average of precipitation. Only a few locations have accumulated more than 80% of the 30-year average since May 1.

Soil Moisture 120cm (2 MB)

  1. Soil Moisture 0 - 30 cm shows a regional representation of soil moisture conditions for the top 30 cm on June 29, 2025 relative to field capacity. Soil moisture is very variable across agro-Manitoba with areas within the same regions showing very dry to wet conditions. The majority of the Interlake is showing dry to very dry conditions.
  2. Soil Moisture 0 - 120 cm shows a regional representation of soil moisture conditions for the top 120 cm on June 29, 2025 relative to field capacity. The majority of the province is showing wet or optimal conditions at the 0 to 120 cm depth. Parts of the Northwest, Interlake and Eastern regions are showing dry conditions.

Growing Degree Days

Percent Normal Accumulated Growing Degree Days (2 MB)

  1. Total Accumulation of Growing Degree Days shows the accumulated growing degree days (GDD) for the period of May 1 – June 29, 2025. Much of the Southwest, Central, and East regions have accumulated more than 550 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 – June 29, 2025. Above normal temperatures early in the season have resulted in GDD Accumulations above 110% of normal for the majority of agro-Manitoba.

  1. Total Accumulated Corn Heat Units illustrates the total accumulated Corn Heat Units (CHU) for the growing season to from May 1 – June 29. More than 900 CHU have accumulated in the majority of the 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 – June 29. CHU accumulations are between 100% and 134% of normal for all regions.

P-Days

Percent Normal P-Days (2 MB)

Total Accumulated P-Days (2 MB)

  1. Total Accumulated P-Days (June 1 – 29) 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 majority of agro-Manitoba has accumulated more than 195 P-Days so far this season.
  2. Percent of Normal Accumulated P-Days (June 1 – 29) 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 95% of normal P-Days so far this season.
