Marine Weather and Tide Forecast for Laguna Beach, FL

UPDATE
Issued at 903 AM EDT Sun Aug 16 2026

Forecast is on track.

SHORT TERM
(Today and Tonight) Issued at 231 AM EDT Sun Aug 16 2026

Another day, another heater. Persistent strong upper ridge fosters widespread high temperatures in the mid 90s with max heat indices of 108-112 degrees. The latter supports a Heat Advisory areawide from 11AM EDT to 8PM EDT. Isolated locations near the Emerald Coast and in/around Apalachicola Nat'l Forest flirt with extreme heat indices of 113+ degrees. Lows merely drop into the upper 70s tonight into tomorrow morning, thus offering little relief.

Afternoon convection aims to focus the most over our FL & SW GA zones, then gradually diminish after sunset. Strong instability amidst Precipitable Waters in excess of 2" means thunderstorms will be capable of strong-gusty winds, frequent lightning, and locally heavy rain. Weak synoptic flow and lack of significant forcing precludes organized severe weather outside of pulsy or merging cells.

LONG TERM
(Monday through Saturday) Issued at 231 AM EDT Sun Aug 16 2026

Long-duration hazardous heat wave spills well into next week and looks to intensify further to which excessive heat products may eventually be necessary for parts of the Tri-State area. Expect high temperatures in the mid to upper 90s and widespread max heat indices in the 110s! Lows in the mid to upper 70s will be common, again offering minimal relief.

Daily chances for thunderstorms remain in the effect. For Monday, most of the convection should be diurnally forced by the seabreeze and surface trough convergence zones. As the work week progresses, the ridge looks to slightly weaken or retrograde westward in response to northern stream troughing. The latter sends a front southward, which will serve as an additional convective focus.

AVIATION
(18Z TAFS)
Issued at 130 PM EDT Sun Aug 16 2026

VFR conditions are generally expected to prevail throughout the TAF period. PROB30 remains in place for potential thunderstorms impacting area terminals later this afternoon with convection forecast to wane shortly after 00Z-01Z. Another brief bout of MVFR visibility is possible at VLD in the pre-dawn

MARINE
Issued at 231 AM EDT Sun Aug 16 2026

Persistent high pressure maintains favorable boating conditions the next several days outside of thunderstorms and potentially fair- weather morning waterspouts. Light to gentle west breezes are forecast through the weekend with daily afternoon seabreezes along the immediate nearshore legs. Prevailing west winds become moderate to start next week.

FIRE WEATHER
Issued at 231 AM EDT Sun Aug 16 2026

The main fire concerns are hazardous heat conditions persisting at least into the first half of next week, daily chances for afternoon thunderstorms, and potentially high dispersions for parts of SW GA & SE AL on Monday afternoon.

High temperatures well into the 90s will be common with heat indices of 108 to 113+ degrees. Even hotter conditions are expected early next week.

Thunderstorms will be capable of frequent lightning, gusty/erratic winds, and locally wetting rains are additional threats.

Prevailing west winds are forecast outside of daily afternoon seabreezes.

HYDROLOGY
Issued at 231 AM EDT Sun Aug 16 2026

Thunderstorms will be capable of producing localized nuisance flooding in urban, poor-drainage, and low-lying areas. Otherwise, there are no significant hydrological concerns the next several days. All area rivers are currently running well below action stage.
