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 26) (PDF 1.5 MB)

Variable precipitation occurred over the past 7 days across agro-Manitoba. Isolated thunderstorms brought significant accumulations to parts of the Northwest, Central, and Eastern regions. The largest accumulations occurred at Sprague Lake (35.7 mm) and San Clara (31.6 mm).  The Southwest corner of the province received little to no precipitation.

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 26 range from 173 mm to 264 mm (Table 2) and are based on 30-year historical data. Since May 1, areas of the Northwest and Interlake regions have accumulated 300 mm of precipitation. Frequent precipitation events have brought seasonal accumulations well above normal for the entire Northwest and most of the Interlake. Areas of the Central and Southwest region also have above-normal accumulation. A few localized stations in the Southwest, Central and Eastern region also have above-normal accumulation.  A few localized areas of the Southwest, Central, and Eastern regions have seen accumulations below 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 26, 2026 relative to field capacity. Most areas are showing wet or optimal conditions. Areas of the East, Central and Interlake regions are showing 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 July 26, 2026 relative to field capacity. The majority of agricultural regions are showing wet or optimal 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 – July 26, 2026. GDD accumulations ranged between 797 and 1112 GDD so far this growing season. Most of Southern Manitoba has accumulated more than 930 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 26, 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 26.  More than 1580 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 26. Above average CHU accumulations were observed throughout the province.  The Northwest, Southwest, Central and Interlake 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 - July 26, 2026)

Region	Range of Normals (mm)	Stations Above Normal (%)	Highest CHU accumulation this season (CHU, % norm.)	Lowest CHU accumulation this season (CHU, % norm.)
Central	1387→ 1584	100	Winkler (1758, 113)	Lakeland (1577, 106)
Eastern	1409 → 1567	95	Steinbach (1689, 114)	Sprague Lake (1427, 99)

Northwest	1195 → 1461	100	Ste. Rose (1607, 114)	The Pas (1417, 112)
Southwest	1121→ 1518	100	Dand (1699, 114)	Wasagaming (1359, 122)

P-Days

Total Accumulated P-Days  (June 1- July 26, 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 430 P-Days so far this season.

Percent of Normal Accumulated P-Days (June 1 - July 26 2026) represents the variation of accumulated physiological days for potatoes (P-Days) from the historical record over a 30-year period. Most of agro-Manitoba PDay accumulations are over 100% of normal so far this season.
