Spring 2024 Climate Outlook

A very warm winter is just about to end as we look ahead toward what’s to come in the spring season.

Last Spring Frost Dates

Knowing the historical last spring frost dates for your area helps growers avoid the risk of frost damage for above-ground vegetation, whether it's for agriculture or horticulture.

Estimating Corn Emergence With Growing Degree Days: Data from May 7, 2021

With corn planting well underway in South Dakota, the next step is monitoring its emergence. One of the factors that can speed up or delay corn emergence is air temperature.

Delayed Planting Due to Soil Temperatures?

Although it can be tempting to get a head start with row crops, it's important to be mindful of soil temperatures and the risks associated with planting early.

Soil Temperature for Planting Spring Crops

Soil temperature is an important consideration for deciding when to begin planting spring crops. If producers in South Dakota would like a quick reference for soil temperatures in their area, the SD Mesonet network measures soil temperature at several weather stations throughout the state.

Low Temperature Damage to Corn and Soybean

Temperatures are forecast to reach 32°F or lower in large areas of South Dakota for several nights beginning on May 7, 2020. While a relatively low percentage of planted crops are likely to be emerged at this point in time, producers may still want to evaluate individual fields for crop damage.

2020 Corn Growing Degree Days Update

Spring planting progress of corn in 2020 has been much ahead of a typical year in South Dakota. Crop development, however, seems slow.

Low Temperature Effects on Winter Wheat

Low temperatures during the early morning hours of May 9–11, 2020 may have had detrimental effects on winter wheat in some areas of South Dakota. However, cooler spring temperatures that have slowed the winter wheat development this year may have actually been beneficial to S.D. producers, as later-maturing wheat is not as susceptible to injury from freezing temperatures.
