How this forecast is built

4 of 5 inputs reporting. Stations, locations, and roles are shown below.

live · forecast

NWS hourly forecast

RoleSupplies the hourly wind, sky, temperature, and precipitation forecast at this destination.

forecast point
Prince Cove Marina · prince-cove-marina
Coordinates
41.6432° N, 70.4119° W

Hourly wind, weather, temperature, and precipitation forecast resolved from the selected latitude/longitude.

live · wave forecast

NWS coastal marine grid

RoleSupplies forecast wave heights, which Boat or Nope uses before buoy-based estimates when available.

marine grid point
Nantucket Sound · 44020
Distance
10.5 NM from destination
Coordinates
41.4970° N, 70.2830° W

Wave-height forecast resolved at NDBC 44020. Used before Boat or Nope's observed-buoy fallback when the grid reports usable wave heights.

live · observed

NDBC 44020

RoleChecks recent observed wind and waves and helps fill gaps when the marine grid has no usable wave value.

buoy
Nantucket Sound · 44020
Distance
10.5 NM from destination
Coordinates
41.4970° N, 70.2830° W

Nearest catalog buoy, 10.5 NM from the selected location. Observed wind and wave reports when this station reports seas.

unavailable · prediction

CO-OPS 8447180

RoleSupplies predicted tide heights and high/low timing for each forecast day.

tide station
Sandwich Marina · 8447180
Distance
8.8 NM from destination
Coordinates
41.7717° N, 70.5067° W

Nearest catalog tide station, 8.8 NM from the selected location. Tide predictions and high/low events in feet relative to MLLW for the available forecast days.

CO-OPS today: 403 Forbidden

AviationWeather KHYA

RoleAdds nearby observed and forecast gust context from METAR and TAF reports.

aviation station
Barnstable Muni · KHYA
Distance
6.1 NM from destination
Coordinates
41.6693° N, 70.2804° W

Nearest aviation candidates: KHYA 6.1 NM, KMVY 17.6 NM, KEWB 24.5 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.
