Weather — Southeast Florida

Write marine weather and conditions cards for SE Florida captains.

NOAA Zones

  • AMZ173 — Coastal waters from Deerfield Beach to Ocean Reef
  • AMZ175 — Offshore waters from Deerfield Beach to Ocean Reef out to 20nm
  • AMZ177 — Offshore waters from Deerfield Beach to Ocean Reef 20-60nm
  • AMZ174 — Coastal waters from Jupiter Inlet to Deerfield Beach
  • AMZ176 — Offshore waters from Jupiter Inlet to Deerfield Beach out to 20nm

Data Sources

  • api.weather.gov — marine forecasts (free, no key)
  • tidesandcurrents.noaa.gov — tide predictions, water temp
  • NDBC buoys: Station 41009 (28nm ESE of Cape Canaveral), Station FWYF1 (Fowey Rocks)
  • Gulf Stream position and temperature data

What SE Florida Captains Care About

Wind & Seas

  • Northeast winds — dangerous for inlet navigation, especially Jupiter and Hillsboro
  • Southeast trade winds — summer pattern, generally fishable
  • Gulf Stream wind-against-current — can build dangerous seas quickly
  • Afternoon thunderstorms — May-Oct pattern, most activity 2-6pm

Tides & Currents

  • Inlet tides — critical for safe navigation, especially Hillsboro and Jupiter
  • Gulf Stream current — 2-4 knots northbound, affects drift fishing
  • ICW tides — shallow areas from Palm Beach Gardens north

Water Temperature

  • Below 72°F — sailfish start showing up (Dec-Jan)
  • Above 78°F — mahi move in close, best offshore fishing (May-Aug)
  • Gulf Stream temp differential — blue water 5-10°F warmer than inshore

Seasonal Patterns

Winter (Dec-Mar)

  • Cold fronts — 3-5 day cycles, north winds behind fronts
  • Trade winds — southeast 10-15 knots between fronts
  • Best fishing weather — calmer seas, cooler water brings sailfish

Summer (May-Sep)

  • Trade winds — consistent southeast 10-15 knots
  • Afternoon storms — daily pattern, morning fishing windows
  • Hurricane season — June-November, peak Aug-Oct

Transition (Apr, Oct-Nov)

  • Variable conditions — weather patterns shifting
  • Best offshore fishing — stable conditions, active fish

Card Types

  • Marine forecast briefing — today/tomorrow conditions, go/no-go for offshore
  • Inlet navigation alert — when conditions make inlets dangerous
  • Gulf Stream forecast — offshore conditions and fishing implications
  • Hurricane prep — tropical weather prep for SE Florida boaters
  • Seasonal weather guide — what to expect this month

Port32 Tie-ins

  • Protected marinas for storm season storage
  • Fuel docks open early to beat afternoon storms
  • Full-service boatyards for hurricane prep (especially Fort Lauderdale)

Style

  • Lead with the actionable take: "Good offshore day" or "Inlets bumpy today"
  • Always mention Gulf Stream conditions for offshore fishing
  • Specific inlet conditions when wind/tide combinations are dangerous
  • Reference afternoon storm timing in summer months
