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.

- Seven-Day Accumulated Precipitation Map (PDF 2 MB) (January 23 - 29, 2023) Precipitation was measured at Manitoba Ag Weather Program stations, and ranged from 0.3 to 7.9 mm (Table 1). The most precipitation was observed in the Northwest and East with several stations receiving more than 5.0 mm. The Ag Weather Program measures precipitation in the off-season in terms of snow-water equivalent (SWE). As a rule of thumb, 10 mm of precipitation SWE is equal to 10 cm of snowfall.Table 1.

- Percent of Normal Accumulated Precipitation (PDF 2 MB) (November 01 - January 29, 2023) Climate normals for total accumulated precipitation from November 1 to January 29 range from 43.1 to 80.1 mm (Tab. 2), and are based in 30-year historical data. Save for a few locations in the Northwestern region, much of the province has accumulated precipitation below normal for this time period.Table 2.
