In September 2026, Missouri experienced its warmest September on record, with a statewide average temperature of 77 degrees Fahrenheit. This surpassed the previous record of 74.8 degrees established in 1931.

The extreme heat was most concentrated in southern and southwestern Missouri, where temperatures in locations such as Marshfield and Licking reached 106 degrees on September 6. This heat coincided with widespread drought conditions in the southern portions of the state, creating a climatic split with northern Missouri, which saw above-average rainfall.

These conditions have impacted the agricultural sector. While northern row-crop farmers have made progress with corn and soybean harvests, soybean yields may have decreased due to dryness. Conversely, the heat and drought have negatively affected livestock production, following a volatile season that began with heavy spring rains that delayed planting in regions like Pettis County.
