Why this sourceThe nearest mapped current station did not return usable predictions, so CAB1401 was selected after live API validation.

Data timingPrediction unavailable

ConfidenceNearby candidates were checked, but none returned usable data during the latest refresh.

No reporting candidateChecked CAB1423, CAB1401, CAB1407, CAB1402; none returned usable data.

Boat or Nope only shows current speed when a nearby NOAA prediction station returns usable flood, ebb, or slack data; tide stage remains clearly labeled as a proxy otherwise.

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

aviation station
Portland Intl Jetport · KPWM
Distance

Coordinates
43.6462° N, 70.3093° W

Why this sourceChosen from the nearest aviation candidates that returned a current METAR or TAF report.

Data timingLatest METAR observation · 2 hr ago

ConfidenceThe selected source is within 25 NM of the destination.

Nearest aviation candidates: KPWM 6.5 NM, KPSM 38.3 NM, KRKD 57.9 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.

Wave character: Wave height and dominant period are combined to distinguish long-period swell from short or steep chop. The label explains comfort and handling; it is not a replacement for a vessel-specific stability assessment.

Current and water level: Current speed is shown only when a nearby NOAA current-prediction station returns usable data. Observed water level is compared with the same station's MLLW tide prediction; tide stage is not presented as measured current speed.

Verdict: Go, Caution, No-Go, or Incomplete uses your wind and sea limits, then applies official active-alert severity and identified wave/current compound risks.
