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 (July 6- July 19) (PDF 1.5 MB)

Variable precipitation occurred over the past 7 days across agro-Manitoba. Once again, rains and isolated thunderstorms brought strong winds and intense rain through parts of the province. The largest accumulations occurred in the Southwest near Birtle, St. Lazare, Minnedosa and Newdale.  Weekly accumulations ranged from 0.2 (Rorketon) to 106 mm (Birtle).

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 19 range from 164 mm to 249 mm (Table 2) and are based on 30-year historical data. Since May 1, areas of the Northwest and Interlake regions have accumulated 250 mm of precipitation. Frequent precipitation events have brought seasonal accumulations well above normal for the entire Northwest and Interlake. Areas of the Central and Southwest region also have above-normal accumulation. Isolated stations in the Northwest and Interlake have accumulated more than 200% of normal precipitation.  A few localized areas of the Southwest, 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 19, 2026 relative to field capacity. Most areas are showing wet or 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 19, 2026 relative to field capacity. The majority of agricultural regions are showing wet conditions at the 0-120 cm depths with a few pockets showing optimal or very wet 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 19, 2026. GDD accumulations ranged between 703 and 990 GDD so far this growing season.

 

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 19, 2026. Due to recent above normal temperatures the majority of agro-Manitoba has accumulated more than 105% of the normal accumultions for this time of year.

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 19.  More than 1200 CHU have accumulated at each station 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 19. Above average CHU accumulations were observed throughout the province.  Every region but the Eastern region saw majority of stations with 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	1235→ 1419	100	Winkler (1574, 113)	Lakeland (1401, 106)
Eastern	1249 → 1401	95	Steinbach (1510, 115)	Sprague Lake (1266, 98)

P-Days

Total Accumulated P-Days  (June 1- July 19, 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 Central and Southwest regions of agro-Manitoba have accumulated more than 425 P-Days so far this season.

Percent of Normal Accumulated P-Days (June 1 - July 19 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.
