South Dakota’s summer of 2025 will be remembered for its record rainfall, especially in the northeast region, where several towns reported more than 20 inches of rain between June and August.
Some stations, including Britton and Wilmot, marked their wettest summer on record. At the same time, the south central and southwest regions stayed dry, with drought conditions holding on in several counties.
The heavy rainfall brought both benefits and challenges. In the northeast, the surplus of rain improved water supplies, boosted pasture and forage growth, and supported healthy wildlife populations, including pheasants and large game animals. Stock ponds filled, and farmers reported stronger hay and alfalfa production compared to the previous dry year.
However, the extreme wetness also caused problems. Flooding occurred in areas like Big Stone and Ortonville, affecting rivers and lakes. Many low-lying farm fields were drowned out, leaving crops under water.
High humidity in July and August made it harder to dry hay, while also increasing plant diseases like rust in corn, foliar diseases in trees, and molds in gardens. Some ranchers had to move cattle from wet pastures to prevent livestock health issues such as foot rot.
August alone set records in several places. Britton reported 11.29 inches, the wettest single month in its 132-year climate history. Other towns like DeSmet and Huron also had record rainfall totals for August.
Looking ahead, the September climate outlook predicts warmer-than-average temperatures for South Dakota, with a late frost more likely than an early one. Precipitation forecasts remain uncertain, though the southeast may see a slightly wetter month.
For farmers, the main challenge moving into fall is crops dry-down. With fields saturated and humidity high, harvest delays are possible, and some may need mechanical drying. Still, improved soil moisture sets a hopeful stage for pasture and range success in 2026.
