Wilmington, NC – The summer of 2025 brought a mix of extremes across the Carolinas, with June and July ranking among the warmest on record before a cooler-than-usual August settled in.
According to the National Weather Service in Wilmington, average summer temperatures across Wilmington, Florence, Lumberton, and Myrtle Beach ran slightly warmer than normal, with overnight lows especially elevated in July. In fact, July set records for the warmest nighttime temperatures in coastal areas.
Wilmington recorded its seventh-hottest July on record with an average high of 88.4 degrees, while Myrtle Beach saw its second wettest August ever, totaling 26.09 inches of rainfall. Florence also logged one of its hottest Julys, reaching 103 degrees on July 27. Lumberton tied historic records, notching its second-hottest July since 1903, before cooling sharply in August.
August, however, provided relief across much of the region. Wilmington experienced its coolest August since 2004, while Florence and Lumberton also reported significant departures below seasonal norms. Myrtle Beach stood out for its rainfall, which was more than 10 inches above average.
Forecasters noted that the unusual trend of warm overnight lows was a key takeaway, highlighting how elevated humidity and persistent heat in July kept nighttime temperatures from dropping. Such conditions, while less visible than daytime highs, can place additional stress on public health, agriculture, and energy systems.
The National Weather Service said that while summer overall averaged only slightly above normal for most locations, the blend of record warmth early and cooler conditions later created sharp contrasts that stood out in the long-term climate record.
