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

Seven-Day Accumulated Precipitation (PDF 2 MB)

Isolated events brought variable rain accumulations the Eastern region. All other regions received trace amounts of precipitation, if any at all. Precipitation for the past week ranged week from 0 mm to 4.7 mm (Table 1).

Table 1. Range of measurements of four-day accumulated precipitation in Manitoba's Agricultural Regions.

 

Percent Normal Precipitation (PDF 2 MB)

Percent Total Precipitation (PDF 2 MB)

Climate normals for total accumulated precipitation from May 1 to June 1 range from 40.6 mm to 81.1 mm (Table 2) and are based on 30-year historical data.  Lack of recent precipitation has resulted in the East, Interlake, and large parts of the Northwest having accumulations under 60% of normal.  Accumulations in the Southwest and parts of the Central regions are up to 140% of the 30-year average since May 1.

Table 2. Summary of measurement of total accumulated precipitation in Manitoba's Agricultural Regions. 

Region	Range of Normals (mm)	Percent of Stations Above Normal (%)	Wettest Location this Season (mm, % norm.)	Driest Location this Season (mm, % norm.)
Central	62.9 → 79.9	12	Cypress River (85, 121%)	Portage (24, 35%)
Eastern	56.6 → 81.1	0	Gardenton (44, 60%)	Elma (3, 5%)
Interlake	50.5 → 69.1	0	Petersfield (45, 78%)	Woodlands (8, 13%)
Northwest	40.6 → 71.8	0	Rorketon (42, 78%)	Minitonas (13, 26%)
Southwest	50.5 → 70.1	48	Carberry EC (102, 147%)	Wasagaming (23, 37%)

 

Soil Moisture 

Soil Moisture 30cm (2 MB)

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 1, 2025 relative to field capacity. Soil moisture is variable across agro-Manitoba. Lack of moisture over the last week has resulted in drying conditions at the surface depths in some areas. The majority of the Eastern and Interlake regions are showing dry to optimal conditions. Much of the Northwest, Southwest and Central regions are showing optimal to wet conditions.
2. Soil Moisture 0 - 120 cm shows a regional representation of soil moisture conditions for the top 120 cm on June 1, 2025 relative to field capacity. The majority of the province is showing wet conditions at the 0 to 120 cm depth. Much of the Eastern region and the eastern portion of the Interlake are showing optimal conditions.

Growing Degree Days

Total Accumulation of Growing Degree Days (2 MB)

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 1, 2025. Much of the Southwest, Central, and East regions have accumulated more than 260 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 1, 2025. Recent above normal temperatures have resulted in GDD Accumulations above 125% of normal for the majority of agro-Manitoba.

Corn Heat Units

1. Total Accumulated Corn Heat Units illustrates the total accumulated Corn Heat Units (CHU) for the growing season to date. More than 430 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. CHU accumulations are well above normal so far this season. All of agro-Manitoba has accumulated more than 115% of CHU when compared to normal.
