Marine Weather and Tide Forecast for Charlotte Harbor, FL

UPDATE
Issued at 840 AM EDT Tue May 5 2026

Partly to mostly sunny skies across the area this morning with light easterly winds. For the rest of the day expect these conditions to continue, but with daytime heating we'll see the west coast sea breeze develop and move inland during the afternoon shifting winds to westerly. There could be enough moisture for an isolated light shower/sprinkle over the interior late this afternoon or evening, but overall expect another warm dry day across the region. Current forecast looks good with no adjustments needed.

AVIATION
(12Z TAFS)
Issued at 840 AM EDT Tue May 5 2026

VFR conditions are expected to prevail with east to southeast winds at 5 to 10 knots this morning becoming westerly at around 10 knots this afternoon as the sea breeze moves inland, then becoming light east to southeast later this evening and overnight.

DISCUSSION
Issued at 1213 AM EDT Tue May 5 2026 Possible light shower through the early morning hours over southwest Florida, otherwise surface high pressure will continue to build over the region today with easterly boundary layer flow, and an onshore sea breeze developing near the coast during the mid/late afternoon hours. Dry warm conditions returning to the area.

A strong U/L ridge will begin to build over the Florida peninsula on Wednesday with increasing large scale subsidence over the forecast area which will cause temperatures to climb several degrees above climatic normal...with highs away from the coast in the lower to mid 90s Wednesday through the upcoming weekend with record high temperatures possible (welcome to a taste of summer). The subsidence will also inhibit afternoon convection creating flattened CU/partly cloudy skies (although potential for little in the way of clouds at all) and rather hot temperatures...and mostly clear nights. NBM likely high on dew points across inland areas during the afternoon hours for the next several days as drier air aloft is expected to mix down. This is not uncommon during the month of May under a strong U/L ridge.
Have adjusted DPs down creating lower RH's. Given the overall drought status across the region, this will likely enhance the wildfire danger...even with the recent rainfall. Winds are expected to remain less than 15 MPH.

A frontal boundary will approach north Florida late in the week stalling across north Florida as it becomes parallel to the U/L flow. There will be a chance of showers/thunderstorms developing over the nature coast as moisture increases and the mid level cap begins to erode. The U/L ridge will gradually give way and be suppressed to the south over the weekend with a slightly better chance of afternoon showers/storms across the forecast area, with the best chance over the interior due to onshore boundary layer flow.

MARINE
Issued at 1213 AM EDT Tue May 5 2026 High pressure will hold over the waters through the week with generally benign conditions expected. Easterly flow today will shift to the south to southeast by mid week...then veer to the west and southwest ahead of a frontal boundary late in the week.

FIRE WEATHER
Issued at 1213 AM EDT Tue May 5 2026 As was mentioned in the discussion above, dry air aloft is expected to mix down over the interior the next couple of afternoons which will create min RH's near to slight below critical levels, which will enhance the fire danger. Winds are expected to remain less than 15 MPH, so an RFW will not be needed.
