Jacksonville started Monday, May 18, 2026, under mostly clear skies, with temperatures in the low 70s and a healthy dose of humidity to kick off the morning. The rest of the day is set to stay mostly sunny and breezy, with highs near 86°F along the coast and warmer readings inland. East winds will strengthen through the afternoon, running around 10-17 mph with gusts into the mid-20s, which will leave the ocean on the choppy side. A High Rip Current Risk remains in effect through late Tuesday night, May 19, for anyone heading to the beach.
Afternoon Winds Pick Up
An onshore flow will keep east to southeast winds blowing at 6-17 mph this afternoon, with gusts topping out around 25-26 mph. That steady breeze will make for hazardous swimming conditions and supports a high rip-current risk along Northeast Florida and Southeast Georgia beaches through late Tuesday night, May 19. Inland neighborhoods will run hotter, with low 90s possible, while immediate coastal spots hang in the mid-80s under mostly sunny skies. These details are from the National Weather Service in Jacksonville; for the full advisory see NWS Jacksonville.
Storms Later This Week
Isolated afternoon showers and inland thunderstorms are most likely Tuesday and Wednesday as the sea breeze pushes away from the coast and farther inland, with rain coverage increasing toward the weekend. Forecast rain chances climb to roughly 40% on Friday, about 50% on Saturday, and near 60% on Sunday as a slow front stalls to the north and pulls in deeper Gulf and Atlantic moisture. If you have outdoor plans, plan on a typical afternoon-and-evening storm window, while coastal areas stay choppier but generally drier until the weekend. More forecast details are available from NWS Jacksonville.
Beach Safety
With surf building and stronger longshore currents expected, lifeguards may close sections of the beach with little notice, so it is safest to swim near a staffed tower when you can. If a rip current pulls you away from shore, avoid fighting it directly, float or tread water, and call or wave for help while conserving your energy. Boaters and small-craft operators should be ready for gusty east to southeast winds this afternoon and use extra caution near shore. Patchy morning fog inland could also trim visibility around sunrise on Tuesday, so give yourself a little extra commute time.
