Why this sourceChosen from the nearest aviation candidates that returned a current METAR or TAF report.

ConfidenceThe selected source is within 25 NM of the destination.

Nearest aviation candidates: KPWM 4.8 NM, KPSM 38.1 NM, KRKD 58.7 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.
