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 22 - 28) (PDF 1.5 MB)

Variable precipitation occurred over the past 7 days across agro-Manitoba. Rains and isolated thunderstorms bringing hail, strong winds, intense rain, and possible tornadoes swept through the majority of the province. The largest accumulations occurred in the Northwest near Roblin, the Southwest in the Waskada area, the Parkland region around Minnedosa, parts of the Central region near Manitou, and the south area of the Interlake. Weekly accumulations ranged from 2 to 123 mm. A tornado was confirmed in the Rossburn area on June 28. San Clara received the highest accumulation of precipitation this week with 123 mm.

Percent Normal Precipitation (PDF 1.5 MB)

Total Accumulated Precipitation (PDF 2.0 MB)

Climate normals for total accumulated precipitation from May 1 to June 28 range from 114 mm to 182 mm (Table 2) and are based on 30-year historical data. Since May 1, areas of the Northwest and Interlake regions have accumulated 180 mm of precipitation. Recent precipitation events have brought seasonal accumulations well above normal for the southern Interlake and parts of the Northwest region. Areas of the Central and Southwest region have near normal accumulations. Areas of the Northwest have accumulated more than 150% of normal precipitation while areas of the southern Interlake near Stonewall have accumulated almost 250% of normal precipitation. Parts of the Southwest around Killarney and areas of the Eastern region are under 80% of the 30-year average precipitation so far this season.

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 June 28, 2026 relative to field capacity. Most areas are showing wet conditions. Localized areas of the Northwest are showing very wet conditions due to recent rains.  Some localized regions are showing optimal or very dry 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 June 28, 2026 relative to field capacity. The majority of agricultural regions are showing wet or very wet to conditions at the 0-120 cm depths.

  

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 – June 28, 2026. GDD accumulations ranged between 417 and 619 GDD so far this growing season. Most of Southern Manitoba has accumulated more than 530 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 – June 28, 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 – June 21.  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 – June 28. Above average CHU accumulations were observed throughout the province.  The Northwest and Southwest regions saw accumulations above 110% of the 30-year normals.

 

Table 4. Summary of total accumulated corn heat units (CHU) and percent deviation from normal in Manitoba's Agricultural Regions (May 1 - June 28, 2026)

Region	Range of Normals (mm)	Stations Above Normal (%)	Highest CHU accumulation this season (CHU, % norm.)	Lowest CHU accumulation this season (CHU, % norm.)
Central	788 → 924	100	Winkler (1014, 113)	Lakeland (870, 104)
Eastern	789 → 911	96	Steinbach (944, 111)	Sprague Lake (754, 92)

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.  The southern regions of agro-Manitoba have accumulated more than 200 P-Days so far this season.

Percent of Normal Accumulated P-Days (June 1 - 28 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.
