Nearest aviation candidates: KJFK 28.6 NM, KFRG 30.9 NM, KBDR 34.4 NM.
Hourly seas: NWS coastal marine-grid wave height is preferred when available. Gaps fall back to the latest NDBC wave observation projected with forecast wind; fallback values are planning estimates, not NOAA wave forecasts.
Verdict: Go, Caution, No-Go, or Incomplete is derived from the boat limits you select for wind and seas.
