Seasonal Crop Summary
September 9, 2026
Northwest Region
Wet conditions early in the week slowed harvest progress in some areas. Warmer temperatures through the week improved field conditions, allowing progress, particularly in areas that received less precipitation. Unsettled weather returned to the region late in the weekend, with heavy rainfall in some areas again slowing harvest progress.
As harvest slowly progresses, many challenges from the season still exist due to infrastructure damage from spring flooding. While major roads have been repaired, there are still roads that are washed out and fields with washouts and cuts.
Fall rye and winter wheat harvest continues and is approximately 95% complete.
Majority of the field pea crop has moved into R7, and harvest continues where crops have reached maturity. Approximately 50% of the crop is harvested. Reported yields have been mixed, ranging from below average to average.
Spring wheat is mostly in the hard dough stage with some later seeded fields behind. Pre-harvest glyphosate applications continue as stages are reached. Approximately 20% of the spring wheat is harvested.
Canola fields continue to range in terms of stages, with most of the crop nearing harvest maturity. Desiccation and swathing is underway in fields that have reached the appropriate stage. Fields that experienced excess moisture have patches of delayed growth that are still flowering. A small start to canola harvest has begun in some early seeded fields.
Majority of the soybean crop is in the R6-R7 stage and looking good where excess moisture hasn’t delayed growth.
Provincial Overview
Another week of scattered extreme weather brought heavy rains to some regions. Thunderstorms early in the week brought large rain accumulations and strong winds to the western regions with Manitou seeing a maximum windspeed of 90 km/hr and Minitonas accumulating 37 mm of rain on August 31. Severe storms on September 6 and 7 brought strong winds and heavy rains to parts of the Central and Interlake regions. Portage la Prairie received 86.9 mm in just one hour on September 6. Other areas that saw intense hourly accumulations include Stonewall, Selkirk, Woodlands, and Elie. Powerful winds caused significant damage throughout the City of Winnipeg and west of Elie.
Climate normals for total accumulated precipitation from May 1 to September 7 range from 230 mm to 356 mm and are based on 30-year historical data. Since May 1, large areas of the Northwest, Southwest, and Interlake regions have accumulated more than 350 mm of precipitation. Seasonal accumulations are above normal for the majority of the Northwest and Southwest regions. Large areas of the Northwest, Southwest, and Interlake regions have seen accumulations over 120% of normal. A few localized areas of the Interlake, Central and Eastern regions have seen accumulations below 90% of the 30-year average.
Total Accumulation of Growing Degree Days shows the accumulated growing degree days (GDD) for the period of May 1 – September 7, 2026. GDD accumulations ranged between 1281 and 1760 GDD so far this growing season. Most of southern Manitoba has accumulated more than 1500 GDD.
