Data timingMarine grid updated · 9 hr ago

ConfidenceThe source is 46 NM away, so local conditions may differ.

Wave-height forecast resolved at marine reference 44005. Used before Boat or Nope's observed-buoy fallback when the grid reports usable wave heights.

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

Data timingLatest METAR observation · 1 hr ago

ConfidenceThe selected source is within 25 NM of the destination.

Nearest aviation candidates: KRKD 7.3 NM, KBHB 46.6 NM, KPWM 51.5 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.
