Marine Weather and Tide Forecast for Lighthouse Point, FL

SHORT TERM
(Today through Thursday)
Issued at 128 AM EDT Wed Jul 22 2026

Not much change in the pattern for today through Thursday as Tropical Storm Bertha continues to slowly work further westward away from the area and surface high pressure centered in the western Atlantic expands more over South Florida. This will cause low level flow to become more easterly, which will shift the focus for shower and thunderstorm development towards Southwest Florida and the interior over the next couple days, although the east coast metro is likely to see some morning shower activity due to speed convergence.
PWATs are expected to climb a little closer to climatological norms at around 1.4-1.6" on average across the area, which is between the 10th-25th percentile for this time of year. Even though it's a little below normal, this amount of moisture should provide enough support for diurnal heating and the sea breezes to spark some convective showers and storms across the region. Hi-res model soundings also highlight moisture filling in pretty well from the 700mb height level and below. Nevertheless, much drier air is still expected to be present above the 700mb height level, suggesting that most activity across the region will be of a shallower and weaker variety. However, it is definitely possible to get a couple of isolated robust storm cores to develop. Sounding parameters indicate SBCAPE and MLCAPE ranging from 2000-3000 J/kg, while DCAPE is in excess of 1000-1200 J/kg particularly in SW Florida along with inverted-V soundings. Therefore, if a stronger core develops, it could produce a downburst of gusty winds that approaches marginally- severe levels, although most likely staying in the sub-severe category.

Heading into Thursday, an upper-level trough will advect across Cuba and the Florida Straits with the brunt of this energy staying away from South Florida. The main impact from this will be an increase in deeper moisture with potential for increasingly widespread coverage of showers and thunderstorms. Surface high pressure will still act as a suppressor, but diurnal heating and the sea breezes will eventually be able to take advantage of the deeper moisture and ignite convective initiation. As easterly flow becomes even more established on Thursday, the focus for the most widespread showers and storms will be across SW Florida as the Gulf breeze gets pinned closer to the coast.

High temperatures today and tomorrow will remain in the low to mid 90s for most areas, although some interior locations might reach the upper 90s. Because of the drier air arriving, no Heat Advisory has been issued due to this drier air helping to lower dew points and relative humidity by a few degrees. This is expected to result in the region avoiding reaching Heat Advisory criteria.

LONG TERM
(Thursday night through Tuesday)
Issued at 128 AM EDT Wed Jul 22 2026

A strong ridge pattern across the western US will continue to expand across to even the southeastern US while surface high pressure remains parked over the Florida Peninsula. This pattern will prevent troughing across most of the Eastern Seaboard from pushing further south, which is expected to keep the local weather primarily sea breeze driven, although some vorticity advection from the upper- level low tracking across Cuba could provide extra support for shower and thunderstorm development on Friday as even deeper moisture returns to the region. Highest rain chances would remain across SW Florida as low level flow remains easterly around the ridge. For the weekend time period, troughing becomes enhanced across the Eastern Seaboard due to the strengthening ridge producing a quasi-meriodional flow at jet stream level. Energy from this trough could push far enough south for Sunday and into early next week, but this still remains uncertain given it is near the end of the forecast period. Regardless, after a brief lull in increased rain shower and thunderstorm activity, the pattern looks to become more active over the next week.

High temperatures each day will continue to reach the low to mid 90s. Overnight lows will range from the low 70s for interior South Florida to the upper 70s and low 80s near the Gulf and Atlantic coasts. Potential for Heat Advisories will continue with each day assessed carefully due to most days being a marginal scenario.

AVIATION
(06Z TAFS)
Issued at 128 AM EDT Wed Jul 22 2026

Scattered SHRA likely across the east coast in the early morning hours, but should push west and away from terminals by 16-17Z. KAPF will have highest risk of impacts today as coverage of SHRA/TS increases after 17-19Z. Winds today will remain SE around 10 kts with KAPF seeing a shift to the SSW after 18Z.

MARINE
Issued at 128 AM EDT Wed Jul 22 2026

A moderate southeasterly wind flow will be in place across the local waters today and is expected to become more easterly to northeasterly for the end of the week as surface high pressure expands further across the area. Scattered showers and thunderstorms will be possible across all local waters each day. Seas across the Gulf waters will range from 2-3 feet with the Atlantic at 2 feet or less into the end of the week.

BEACHES
Issued at 128 AM EDT Wed Jul 22 2026

A moderate risk for rip currents continues for the Collier beaches today. This risk is expected to subside after today.
