Living at the coast is pretty amazing for the most part. We say “for the most part” because there is one key exception to the rule: Hurricane season, which resumes today and will run through November 30. Once again, we’ll be monitoring the tropics with vigilance throughout the summer and fall, watching for potential threats to the Carolina coastline that might require us to hide our cows and head west.

Weekend forecast: Nice respite for Saturday, a storm possible Sunday

/ May 30, 2025 at 8:45 PM

A welcome respite from the humidity and constant threat of storms arrives in the wake of a cold front on Saturday. It’ll be noticeably cooler in the morning, with lows bottoming out in the low 60s with the cooler and drier air setting into place. Temperatures warm nicely to the mid-80s in the afternoon, and humidity will be on the low side for the end of May, which is a nice cherry on top.

A stalling front and some energy aloft could stir up a few thunderstorms Sunday afternoon, but otherwise it should still be a decent day of weather outside of those storms as dewpoints mix down to the upper 50s in the afternoon. You’ll want to keep an eye out for popups as you embark on your outdoor activities, but many of us should be rain-free for much of the day.
