ConfidenceThe source is 31.8 NM away, so local conditions may differ.

Nearest aviation candidates: KGON 31.8 NM, KBDR 37.3 NM, KWST 40.8 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.
