Nearest aviation candidates: KFRG 6.1 NM, KISP 10.7 NM, KJFK 21.6 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.
