- 40.7939° N, 73.1018° W
Why this sourceChosen from the nearest aviation candidates that returned a current METAR or TAF report.
Data timingLatest METAR observation · 17 min ago
ConfidenceThe selected source is within 25 NM of the destination.
Nearest aviation candidates: KISP 5.8 NM, KFRG 19.6 NM, KBDR 25.3 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.
