Destin is flying yellow and purple flags, with the strongest winds on the coast today — variable northwest to west at 3–17 mph. Water is 86°F and waves are at 1.4 ft. Rain chances are 40 percent with highs near 91°F. The Extreme Heat Warning has expired, and today runs under a Heat Advisory with heat index values of 110 to 111.
The National Weather Service has a Heat Advisory in effect for Escambia, Santa Rosa and Okaloosa coastal counties from 11:00 AM to 8:00 PM CDT today, with heat index values of 110 to 111 degrees. This is a step down from yesterday's Extreme Heat Warning, but it is still the seventh consecutive day of advisory-level or warning-level heat. Drink water steadily rather than waiting until you are thirsty, wear lightweight loose clothing, and keep strenuous activity to the early morning or evening. Take breaks in shade or air conditioning; a beach umbrella alone is not enough at these numbers.
Watch for heat exhaustion: heavy sweating, weakness, dizziness, nausea or confusion. Anyone showing those signs should get to a cool place and drink water immediately. If someone becomes unresponsive or loses consciousness, call 911 — heat stroke is a medical emergency. Check on elderly neighbours and anyone with health conditions, and never leave children or pets in a parked car.
A week of accumulated exposure is the part to take seriously. Overnight lows have stayed in the low 80s, so there has been little recovery between days and fluid deficit has been building since last Thursday. Shorten the session rather than pushing through it.
The most recent National Weather Service guidance covering today put rip current risk at moderate with surf around 2 feet. Moderate means life-threatening rip currents are possible in the surf zone. Swim near a lifeguard, stay within your depth, and keep clear of piers, jetties and groins where currents concentrate. If you are caught in one, do not swim against it: swim parallel to shore until you are out of the pull, then come in at an angle. Check the live page before you go in — conditions can be re-rated during the day.
Yellow means moderate hazard: moderate surf, moderate currents, or both. Swimming is allowed but calls for caution. At 1.4 ft with rip risk at moderate and gusty variable winds, the flag reflects real conditions today. Stay close to shore, swim near a lifeguard, and give the East Pass jetties a wide berth: rip currents concentrate around structure like that.
The purple flag is up alongside the yellow, meaning dangerous marine life has been reported in the water — on this coast in August that usually means jellyfish or Portuguese man-of-war. Purple is an additional warning, not a downgrade of the yellow flag. Man-of-war tentacles still sting after the animal washes ashore, so give anything stranded on the sand a wide berth and keep children and dogs away from it. Shuffle your feet in the shallows for rays.
Is It Safe to Swim at Destin Today?
With caution. Surf is 1.4 ft and rip current risk is moderate, so swim near a lifeguard, stay within your depth, and keep clear of the pass. The purple flag means stinging marine life is in the water. Winds are shifting through northwest, southwest and west today at up to 17 mph, so surface conditions may be choppier and less predictable than the wave height suggests. The heat is easier than yesterday but a heat index of 110 still calls for a short session and real shade.

Destin runs a much smaller tidal range than Navarre or Pensacola, but today's swing runs almost twelve hours from the pre-dawn high to a 0.13 ft low mid-afternoon. The morning fall is the usable portion — the low itself lands in the hottest part of the advisory window. Full tide charts are on the live tides page.
7-Day Outlook
Thursday should improve with reduced rain chances and lighter winds, heat index values as high as 109°F.
