Wilmington, Delaware – Spring break travelers heading through Delaware could face a late-season freeze as overnight temperatures fall to around 25°F between March 16 and March 20, bringing icy early-morning conditions just days before the official start of spring.
According to the National Oceanic and Atmospheric Administration (NOAA), a broad section of the eastern United States—from Minnesota down to East Texas and east to the Atlantic coast—shows a 60–70% probability of below-normal temperatures during that timeframe. The Mid-Atlantic region, including Delaware, sits squarely within this colder-than-average air mass.
Cities including Wilmington, Dover, and Newark could see overnight temperatures dipping to around 25°F, particularly during clear nights when heat escapes quickly after sunset.
Daytime highs may recover into the upper 30s and lower 40s, but those readings will still run several degrees below typical mid-March averages.
Drivers using major travel routes including Interstate 95, Route 1, and Route 13 during spring break should be alert for patchy frost on bridges and elevated roadways during early morning hours, especially before sunrise.
Along the coast, Rehoboth Beach and Lewes may stay slightly milder due to the Atlantic influence, though brisk winds could still make temperatures feel colder during early morning and evening hours.
The colder pattern may persist through March 20, and additional advisories could follow if overnight temperatures continue dropping toward the mid-20s across Delaware during the opening week of spring. ❄️🌡️🥶
