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 (June 29 - July 5) (PDF 1.5 MB)

Variable precipitation occurred over the past 7 days across agro-Manitoba. Once again, rains and isolated thunderstorms brought hail, strong winds, intense rain, and possible tornadoes swept through the majority of the province. The largest accumulations in the Southwest near Boissevain and Souris, as well as the Northwest region in the already water-logged areas of San Clara, Ethelbert, Dauphin, Minnedosa and Russell.  Overland flooding and overflowing rivers and streams have caused many communities, including the City of Brandon, to declare local states of emergency.  Weekly accumulations ranged from 9 (Sprague) to 188 mm (Boissevain).  A tornado was confirmed in the Whyte Ridge neighbourhood of Winnipeg on June 29.

Percent Normal Precipitation (PDF 1.5 MB)

Total Accumulated Precipitation (PDF 2.0 MB)

Climate normals for total accumulated precipitation from May 1 to July 5 range from 131 mm to 211 mm (Table 2) and are based on 30-year historical data. Since May 1, areas of the Northwest and Interlake regions have accumulated 220 mm of precipitation. Frequent precipitation events have brought seasonal accumulations well above normal for the entire Northwest and Interlake regions. Areas of the Central and Southwest region also have above-normal accumulations due to recent rainfall. Areas of the Northwest have accumulated more than 200% of normal precipitation.  A few localized areas of the Central, and Eastern regions have seen accumulations under 80% of the 30-year average.

Soil Moisture

Soil Moisture 30cm (1.5 MB)

Soil Moisture 0 - 30 cm shows a regional representation of soil moisture conditions for the top 30 cm on July 5, 2026 relative to field capacity. Most areas are showing wet or very wet conditions. Some localized areas are showing optimal conditions. 

 

Soil Moisture 120 cm (1.5 MB)

Soil Moisture 0 - 120 cm shows a regional representation of soil moisture conditions for the top 120 cm on July 5, 2026 relative to field capacity. The majority of agricultural regions are showing wet or very wet to conditions at the 0-120 cm depths with a few pockets showing optimal conditions.

  

Growing Degree Days

Total Accumulated Growing Degree Days (PDF 2.0 MB)

Total Accumulation of Growing Degree Days shows the accumulated growing degree days (GDD) for the period of May 1 – July 5, 2026. GDD accumulations ranged between 497 and 731 GDD so far this growing season. Most of Southern Manitoba has accumulated more than 600 GDD.

 

Percent Normal Accumulated Growing Degree Days  (PDF 2.0 MB)

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 – July 5, 2026. The majority of regions have above normal GDD accumulations.

Corn Heat Units

Total Accumulated Corn Heat Units (PDF 2.0 MB)

Total Accumulated Corn Heat Units illustrates the total accumulated Corn Heat Units (CHU) for the growing season to from May 1 – July 5.  More than 720 CHU have accumulated in much of the Southwest, Central, and Eastern regions since May 1.

 

Percent Normal Accumulated Corn Heat Units (PDF 2.0 MB)

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 – July 5. Above average CHU accumulations were observed throughout the province.  The Northwest and Southwest regions saw accumulations above 110% of the 30-year normals.

Region	Range of Normals (mm)	Stations Above Normal (%)	Highest CHU accumulation this season (CHU, % norm.)	Lowest CHU accumulation this season (CHU, % norm.)
Central	931 → 1085	100	Winkler (1191, 113)	Lakeland (1036, 105)
Eastern	937 → 1071	95	Steinbach (1123, 112)	Sprague Lake (918, 95)

P-Days

Total Accumulated P-Days  (June 1-28, 2026) 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.  Most of the southern regions of agro-Manitoba have accumulated more than 260 P-Days so far this season.

Percent of Normal Accumulated P-Days (June 1 - July 5 2026) 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 PDay accumulations to over 100% of normal so far this season.
