Wave-height forecast resolved at marine reference 44097. Used before Boat or Nope's observed-buoy fallback when the grid reports usable wave heights.
NDBC 44097
RoleChecks recent observed wind, waves, and water temperature and helps fill gaps when the marine grid has no usable wave value.

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: KWST 13.4 NM, KMTP 16.1 NM, KGON 22.1 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.
