Why this sourceNo nearby mapped station returned predictions during this refresh; no current speed is inferred from tide height alone.
Data timingPrediction unavailable
ConfidenceNearby candidates were checked, but none returned usable data during the latest refresh.
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.

ConfidenceThe selected source is within 25 NM of the destination.
Nearest aviation candidates: KJFK 0.7 NM, KFRG 16.1 NM, KISP 30.8 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.
