How this forecast is built

5 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
Block Island · block-island
Coordinates
41.1740° N, 71.5800° 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
Block Island · 44097
Distance
23.9 NM from destination
Coordinates
40.9690° N, 71.1270° W

Wave-height forecast resolved at NDBC 44097. Used before Boat or Nope's observed-buoy fallback when the grid reports usable wave heights.

live · observed

NDBC 44097

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

buoy
Block Island · 44097
Distance
23.9 NM from destination
Coordinates
40.9690° N, 71.1270° W

Nearest catalog buoy, 23.9 NM from the selected location. Observed wind and wave reports when this station reports seas.

live · prediction

CO-OPS 8452660

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

tide station
Newport · 8452660
Distance
22.9 NM from destination
Coordinates
41.5050° N, 71.3260° W

Nearest catalog tide station, 22.9 NM from the selected location. Tide predictions and high/low events in feet relative to MLLW for the available forecast days.

live · observed + forecast

AviationWeather KWST

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

aviation station
Westerly State · KWST
Distance
14.5 NM from destination
Coordinates
41.3500° N, 71.8000° W

Nearest aviation candidates: KWST 14.5 NM, KMTP 16.7 NM, KGON 23.2 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.
