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
Ipswich Bay · ipswich-bay
Coordinates
42.6793° N, 70.6680° 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
Massachusetts Bay · 44029
Distance
10.4 NM from destination
Coordinates
42.5230° N, 70.5660° W

Wave-height forecast resolved at NDBC 44029. Used before Boat or Nope's observed-buoy fallback when the grid reports usable wave heights.

live · observed

NDBC 44029

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

buoy
Massachusetts Bay · 44029
Distance
10.4 NM from destination
Coordinates
42.5230° N, 70.5660° W

Nearest catalog buoy, 10.4 NM from the selected location. Observed wind and wave reports when this station reports seas.

live · prediction

CO-OPS 8443970

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

tide station
Boston · 8443970
Distance
25.9 NM from destination
Coordinates
42.3530° N, 71.0500° W

Nearest catalog tide station, 25.9 NM from the selected location. Tide predictions and high/low events in feet relative to MLLW for the available forecast days.

AviationWeather KLWM

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

aviation station
Lawrence Muni · KLWM
Distance
20.2 NM from destination
Coordinates
42.7172° N, 71.1234° W

Nearest aviation candidates: KLWM 20.2 NM, KBOS 24.1 NM, KPSM 24.9 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.
