Seasonal Crop Summary
June 23, 2026
Northwest Region
A mixed week of weather included cool overnight temperatures, moderate daytime temperatures and frequent showers across most of the region. The highest daytime temperature was recorded at Alonsa station at 23.7°C, while lowest overnight temperature was recorded at Laurier at 3.2°C. Most of the region received precipitation with Swan River and Swan Valley stations recording the highest accumulated amount of 22 mm. The lowest accumulated amount was recorded at Ste. Rose station at 0.6 mm.
Many of the same challenges exist this week as the last, areas that received significant rainfall amounts and overland flooding damage continue to recover. Frequent showers during the week contributed to already saturated soils, causing water in low areas of fields again. Wet conditions have posed a challenge in finishing seeding, reseeding and timely spraying. Damages continue to be assessed in the Minitonas/Swan Valley region where significant rainfall/overland flooding occurred. Infrastructure damage/road washouts continue to be repaired and have added to the many challenges this year as access became difficult.
Field pea seeding is complete and where conditions are good, crops are advancing nicely. Stages range from V2-V6.
As of June 20, spring wheat and spring cereal seeding is approximately 90% complete. Crop stages range from seedling to tillering.
As of MASCs spring seeding deadline of June 20, canola seeding is approximately 85% complete across the region. Stages range from cotyledon to 4-6 leaf. Herbicide applications have occurred where conditions and stages allow.
Soybean seeding is complete. Soybeans are mostly at V1 stage.
Weather Report
Variable precipitation occurred over the past 7 days across agro-Manitoba. Isolated rains swept through the Southwest and Central regions with
accumulations ranging from 0 to 34 mm. Areas of the Interlake received less than 5 mm of rain. Already flooded areas around Swan River and
Swan Valley received 22 mm of rain. Somerset received the highest accumulation of precipitation this week with 34 mm.
Climate normals for total accumulated precipitation from May 1 to June 21 range from 89.7 mm to 154.0 mm and are based on 30-year historical
data. Since May 1, large portions of the Northwest, Interlake, and Eastern regions have accumulated more than 80 mm of precipitation. Recent
precipitation events have brought seasonal accumulations well above normal for the Interlake and parts of the Northwest region. Areas of the
Northwest have accumulated more than 150% of normal precipitation while areas of the southern Interlake near Stonewall have accumulated more than 250% of normal precipitation. The majority of the Southwest is still below normal at under 70% of the 30-year average precipitation so far
this season.
Total Accumulation of Growing Degree Days shows the accumulated growing degree days (GDD) for the period of May 1 – June 21, 2026. GDD accumulations ranged between 350 and 522 GDD so far this growing season. Most of Southern Manitoba has accumulated more than 425 GDD.
