Weather — SW Florida

Write marine weather and conditions cards for SW Florida captains.

NOAA Marine Zones

  • AMZ152 — Ten Thousand Islands waters (Marco Island area)
  • AMZ151 — Naples to Englewood coastal waters
  • AMZ155 — Charlotte Harbor and Pine Island Sound
  • GMZ850 — Gulf waters 20-60nm west of Naples/Ft Myers
  • GMZ856 — Gulf waters east of 83W north of 26N (offshore Charlotte Harbor)

NOAA Weather Stations

  • NDBC Station 42036 — West Tampa (150nm WNW of Naples) — Gulf conditions
  • NDBC Station FMRF1 — Fowey Rocks (SE Florida) — regional patterns
  • Naples Tide Station — 8725110
  • Fort Myers Tide Station — 8725520

Data Sources

  • api.weather.gov — marine forecasts and warnings
  • tidesandcurrents.noaa.gov — tide predictions, water temps
  • NWS Miami office covers SW Florida marine weather
  • Local observations from Naples, Fort Myers airports

What SW Florida Captains Care About

Wind Patterns

  • East winds — great for Gulf runs, calm on inshore flats
  • West/Southwest — can make passes rough, especially Gordon Pass and Caxambas
  • North winds — push water out of shallow areas, can make flats unfishable
  • Anything over 20kt — small boats should stay protected

Thunderstorms

  • Peak season: May–October, especially July-September
  • Daily pattern: Sea breeze convergence creates afternoon storms
  • Lightning danger: SW Florida has among highest strike rates in US
  • Morning fishing: Best window before storms build

Tides & Water Levels

  • Low tide navigation: Many SW Florida areas very shallow - Pine Island Sound, 10,000 Islands
  • Spring tides: Extreme lows can strand boats, extreme highs flood docks
  • Wind-driven tides: Strong winds can affect water levels more than predicted tides

Seasonal Patterns

  • Winter (Dec-Mar): Cold fronts bring north winds, clear skies. Best weather window
  • Spring (Apr-May): Variable winds, occasional fronts, generally great conditions
  • Summer (Jun-Aug): Daily storms, hot, humid, southeast trade wind pattern
  • Fall (Sep-Nov): Hurricane season peak, but often great fishing weather

Red Tide

  • Karenia brevis blooms — monitor Florida Fish and Wildlife red tide reports
  • Respiratory effects — can cause coughing, throat irritation
  • Dead fish — major blooms cause fish kills, beach closures
  • Southwest Florida susceptible — Gulf currents can concentrate blooms here

Special Considerations

Passes & Inlets

  • Gordon Pass (Naples) — shallow, can be very rough in west winds
  • Caxambas Pass (Marco) — better protected, but watch for shoaling
  • Captiva Pass — can be challenging, local knowledge required
  • Boca Grande Pass — deep water but strong currents, wind-against-tide rough

Shallow Water Areas

  • 10,000 Islands — extremely shallow, tide-dependent navigation
  • Pine Island Sound — vast shallow area, draft limitations
  • Charlotte Harbor flats — extensive shallow areas, wind affects water levels

Hurricane Season

  • Peak months: August–October
  • Storm surge risk: Southwest Florida very vulnerable due to shallow continental shelf
  • Prep time: Boats need to be secured or moved inland well before arrival
  • Post-storm: Navigation aids may be moved, debris common

Card Types

  • Marine forecast briefing — conditions for next 24-48 hours, go/no-go assessment
  • Weekend outlook — longer range planning for trips
  • Storm prep — tropical weather awareness, hurricane preparation
  • Seasonal guide — what to expect this month in SW Florida waters
  • Pass conditions — specific guidance for inlet conditions based on wind/tide
  • Lightning safety — when to get off the water (30/30 rule)

Port32 Tie-ins

  • Protected marina storage keeps boats safe during severe weather
  • Fuel docks allow topping off before weather windows
  • Weather monitoring helps optimize launch scheduling
  • Covered storage protects from UV during intense summer sun

Style

  • Lead with actionable guidance: "Great day for the backcountry" or "Rough on the passes today"
  • Specific wind speeds, directions, and timing
  • Include tide timing when relevant for shallow areas
  • Always mention thunderstorm timing during summer months
  • Reference local knowledge (Gordon Pass rough in west wind, etc.)
