Weather Conditions and Reports

From month to month, Manitoba's ag weather program retrieves data every 15 minutes from equipment across the province. About 109 stations monitor air temperature, relative humidity, rainfall, wind speed/wind direction and soil temperature.

In addition to regular weather and soil reports, producers can access more specialized tools during the growing season. These tools include disease and crop condition reports, which helps producers determine the safest and most effective times to spray.

Latest weather and conditions

1. Seven-Day Accumulated Precipitation (Nov 05 - 11, 2018) shows the amount of precipitation received across agro-Manitoba last week. The northwest region got the highest amount of precipitation last week with Swan River receiving the highest amount: 19.6 mm. Precipitation amounts decreased from west to east of agro-Manitoba.  
2. Total Accumulated Precipitation (November 01 – 11, 2018) showed that the eastern and Interlake regions have received less than 6 mm of total precipitation in the first 2 weeks of November. The map is similar to the seven-day map which showed increasing precipitation from east to west. The northwest region, around Swan River has the highest total precipitation since November 01 with 22 mm of combined rain and snow. 
3. Percent of Normal Accumulated precipitation (November 01 – 11, 2018) relates accumulated precipitation since November 1^st to a 30-year historical record. Areas in the Northwest and Southwest regions have received above normal precipitation. Although the total precipitation at McAuley, Miniota, Hamiota, Kenton and Rivers were not the highest, the area has received about 3 to almost 7 times the historical average precipitation the area normally receive. 
4. Soil Moisture (November 11, 2018, top 0-30 cm) shows that agro-Manitoba mostly has adequate soil moisture condition with dry conditions around the Interlake and the southeast corner of the province. The map shows soil moisture in the top 0-30 cm when compared to the soil saturation level (maximum recorded at that station). 
5. The average daily soil temperature across agro-Manitoba can be found at (http://www.gov.mb.ca/agriculture/weather/soil-temperature.html).   
6. The Manitoba Weather Report shows weather information by individual weather station.
