Jacksonville woke up to mostly clear skies and a comfortable 60°F on Tuesday morning, April 21, 2026, but the calm start is masking a two-front hazard kind of day. Inland neighborhoods are staring down critically low humidity and gusty onshore winds this afternoon, while area beaches are in for rough surf and dangerous rip currents through late tonight.
Afternoon Fire Danger
A Red Flag Warning is in effect from 11 AM to 8 PM Tuesday for portions of inland northeast Florida, where minimum relative humidity is expected to fall into the 20s and the afternoon seabreeze could push wind gusts into the 20s, creating critical wildfire conditions. Residents are urged to avoid outdoor burning, secure yard debris, and report any smoke or small fires immediately, according to the National Weather Service Jacksonville.
Beach Hazards And Rip Currents
Coastal areas are under a Rip Current Statement from 8 AM through late tonight, with surf running around 4 to 6 feet and a high risk of dangerous rip currents that can quickly pull swimmers offshore. The National Weather Service warns, "Dangerous rip currents expected," and urges beachgoers to swim near lifeguards and, if caught in a rip, to float and signal for help rather than trying to fight the current.
What To Expect This Week
Temperatures will stay warm through the week with highs near 80 to 84°F and a gradual warm-up into the upper 80s by the weekend. Scattered afternoon storms are possible Saturday and Sunday as the pattern begins to shift.

Safety And Planning
If you have outdoor plans today, postpone any open-flame activities and secure loose yard items before the seabreeze kicks in. Beachgoers should check lifeguard flags, avoid wading in rough surf, and boaters should exercise caution close to shore.
