How this forecast is built
5 of 5 inputs reporting. Stations, locations, and roles are shown below.
NWS hourly forecast
RoleSupplies the hourly wind, sky, temperature, and precipitation forecast at this destination.
- forecast point
- Upper Bay Anchorage Area Number 23A · upper-bay-anchorage-area-number-23a
- Coordinates
- 40.6365° N, 74.0638° W
Hourly wind, weather, temperature, and precipitation forecast resolved from the selected latitude/longitude.
NWS coastal marine grid
RoleSupplies forecast wave heights, which Boat or Nope uses before buoy-based estimates when available.
- marine grid point
- New York Harbor Entrance · 44065
- Distance
- 23.1 NM from destination
- Coordinates
- 40.3680° N, 73.7010° W
Wave-height forecast resolved at NDBC 44065. Used before Boat or Nope's observed-buoy fallback when the grid reports usable wave heights.
NDBC 44065
RoleChecks recent observed wind and waves and helps fill gaps when the marine grid has no usable wave value.
- buoy
- New York Harbor Entrance · 44065
- Distance
- 23.1 NM from destination
- Coordinates
- 40.3680° N, 73.7010° W
Nearest catalog buoy, 23.1 NM from the selected location. Observed wind and wave reports when this station reports seas.
CO-OPS 8518750
RoleSupplies predicted tide heights and high/low timing for each forecast day.
- tide station
- The Battery · 8518750
- Distance
- 4.5 NM from destination
- Coordinates
- 40.7006° N, 74.0142° W
Nearest catalog tide station, 4.5 NM from the selected location. Tide predictions and high/low events in feet relative to MLLW for the available forecast days.
AviationWeather KJFK
RoleAdds nearby observed and forecast gust context from METAR and TAF reports.
- aviation station
- New York/JFK Intl · KJFK
- Distance
- 13.7 NM from destination
- Coordinates
- 40.6392° N, 73.7639° W
Nearest aviation candidates: KJFK 13.7 NM, KFRG 30.1 NM, KMJX 44.1 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.
