As we gear up for the summer months, brace yourself for a sizzling season ahead. According to forecasts from the USDA Midwest Climate Hub, Dr. Dennis Todey warns of above-average temperatures dominating much of the country from July through September. Todey’s insights, shared during a webinar sponsored by the Iowa Farm Bureau Federation, signal a notable shift in weather patterns.
The western third of the nation, excluding parts of California’s coast along with the upper New England states, is predicted to face particularly intense heat. While the mercury level soars, precipitation forecasts remain neutral for most regions. However, a swath along the eastern seaboard may experience above-average rainfall, which could serve as some relief from the scorching temperatures.
The impending change in weather is attributed to a rapid transition from the current El Niño pattern to a La Niña phase, expected to kick in between June and August 2024. This shift follows a brief El Niño period that brought unusually mild winters, particularly evident in states like North Dakota, Minnesota, and New York.
However, the flip to La Niña raises concerns, especially for regions already grappling with drought conditions. States like Iowa have been in a moderate drought since July 2021, with pockets of extreme and exceptional drought in areas like Montana, New Mexico, and Texas. The uncertainty surrounding precipitation patterns highlights the importance of timely rainfall throughout the summer months.
“While temperatures are extending growing seasons by about 10 days per decade, there’s been a concerning trend of mid-summer dryness over the past 20 years, with more rainfall occurring in the spring.”

As farmers prepare for the planting season, Dr. Todey offers practical advice to navigate these challenging conditions:
- Adjust yield goals considering potential moisture limitations.
- Optimize planting timing to capitalize on spring moisture.
- Minimize tillage to preserve soil moisture.
- Monitor water sources closely for livestock and irrigation, preparing contingency plans if needed.
As the summer draws near, it’s imperative for our agricultural communities to prepare for the heat and adapt their practices accordingly to minimize potential impacts on crops and livestock.
