Marine Weather and Tide Forecast for New Smyrna Beach, FL

PREVIOUS DISCUSSION
Issued at 212 AM EDT Thu Jul 17 2025

Current-Tonight-Fri...ISOLD to WDLY SCT showers/lightning storms over the local coastal waters may occasionally brush the coast in the SSE steering flow this morning. Otherwise continued mild and muggy with temps and dewpoints generally in the 70s areawide. The Atlc ridge axis will remain near to just north of ECFL thru late work-week. This will continue a SERLY flow across the area.
Morning winds 5-10 mph increasing to 10-15 mph along the coast with sea breeze passage. Remaining moist for one more day with PWATs surging north of 2 inches, then drier air moves into the area on Fri. Keeping 50-70pct for PoPs across the coverage warning area today (highest inland from the coast), then chances decrease into Fri (20-30pct coast & 30-50pct interior). Aloft, height rises occur in the mid-levels as ridging builds westward toward the peninsula, though still rather cool temps aloft forecast (-7C to -9C at H500). Primary storm impacts remain occasional to frequent cloud-to-ground lightning strikes, gusty winds locally 40-50 mph, and torrential downpours - minor/nuisance flooding possible for locales that have recently seen multiple rounds and other prone low-lying areas.

Increasingly hot and humid conditions, with highs in the L90s today and L-M90s on Fri. Peak afternoon heat indices range from 102-107 degrees each day. Overnight lows will continue in the 70s with conditions humid.

Sat-Tue...The broad mid-level ridging builds over the peninsula on Sat, then pushes into the Gulf Sun and across the Deep South Mon- Tue, resulting in mid-level height decreases across the peninsula late in the period. At the surface, weak ridging settles across the area Sat-Sun, then into south FL Mon-Tue. Heat and humidity continue to build across the area into the weekend and on Mon with highs in the L-M90s, falling slightly to the L90s everywhere on Tue. Cannot rule out a few U90s over the interior this weekend. Have presently capped peak heat indices in the grids at 107F for the extended, but potential is there for some readings above 108F which could reach Heat Advisory thresholds - esp across the interior. Any relief from the heat may come from sea breeze passage near the coast and scattered afternoon/evening showers/storms, but coverage will be lower this weekend (highest across the interior). PoPs forecast to increase gradually early next week as deeper moisture may move back into the area. Overnight lows continue in the 70s with conditions muggy.

Today-Mon...The Atlc ridge axis remains fixated near to just north of the local waters into late week, slowly sliding south into early next week. A persistent ESE/SE flow thru Sat, becoming light offshore Sat-Sun nights - though daily sea breezes will transition flow onshore during the afternoon/early evening periods this weekend. Wind speeds typically AOB 15 kts. Seas primarily 2-3 ft. Winds/seas locally higher invof showers and lightning storms. Fairly high precip coverage again, today, then drier air moves into the area Fri-Sun (below normal rain chances), then slightly increasing chances again on Mon. Primary storm threats remain cloud-to-water lightning strikes, gusty winds, and heavy downpours.

AVIATION
(18Z TAFs)
Issued at 125 PM EDT Thu Jul 17 2025

Wave of deeper moisture moving northward across the area has led to an earlier start of convection through this morning and early afternoon. Coverage of this activity will continue to increase through the remainder of the afternoon and early evening as it lifts N/NW, becoming scattered to numerous. Have Tempo groups for showers/storms along the coast through 20Z, and then across the interior from 19-23Z for MVFR impacts and variable/gusty winds. A few stronger storms will be possible producing strong wind gusts, frequent lightning and locally heavy rainfall. This activity will wind down past sunset, with dry conditions forecast overnight.
Southeast winds along the coast will still be breezy/gusty at times this afternoon up to 11-14 knots with gusts to 15-20 knots, mainly from KMLB southward. Otherwise, southeast winds will be around 5-10 knots decreasing to 5 knots or less into tonight.
