Temperatures in Washington County are expected to reach 100 degrees this week, marking one of the hottest July stretches in local memory and putting the region’s heat in stark historical and regional perspective.
The county’s all-time record high for July stands at 99.6 degrees, set in 1930, according to National Weather Service data. Recent decades have seen average July highs hover around 92 degrees, with few days exceeding the century mark. A forecasted high of 100 this week places the area back in territory rarely seen since the Dust Bowl era.
“Washington County is facing conditions we haven’t seen in nearly 100 years,” said a National Weather Service forecaster. “Temperatures at this level are not only extreme – they can be dangerous, especially for vulnerable communities.”
By contrast, July lows in Washington County have rarely dropped below the low 70s. The coldest July nights on record in neighboring Delta counties have been in the low 60s, such as a statewide minimum of 61 degrees recorded in 2014. High temperatures, however, have consistently remained well above 80, making cool July weeks equally rare.
Elsewhere in Mississippi, the July average high is about 92 degrees, with the state record for the month reaching 104 degrees in 2011. The current heat wave is pushing most of the state above its historical averages, with cities such as Jackson and Greenville forecasting highs in the upper 90s. The Delta’s inland location, however, often makes counties like Washington among the hottest spots in the state.
Across the Southeast, July temperatures typically reach highs between 90 and 92 degrees, with humidity and rainfall providing modest relief. But forecasters say Mississippi’s Delta region is among the hottest parts of the Southeast this week, with 100-degree highs well above regional averages.
“This kind of heat is tough on everyone, particularly those without air conditioning or reliable access to water,” the NWS spokesperson said. “We urge residents to take precautions—and to check on their neighbors.”
Washington County Emergency Management encourages residents to limit outdoor activities during the hottest hours, remain hydrated, and seek cool shelter when possible.
