U.S. COAST RADAR
What stands out in the next 7 days?
The radar ranks real NOAA high/low events by local rarity and daylight, then adds current buoy context where available. No generic “best beach” list.

The useful question is not “when is high tide?”
It is: what unusual thing is happening near a coast I can visit, and when is the best useful window? The engine turns source data into ranked decisions instead of reproducing a chart you can find elsewhere.
01RarityHow unusual is this high or low tide for this station’s upcoming month?
02UsabilityDoes the event overlap daylight, sunrise or sunset?
03Live contextIs observed water running above prediction? What is the buoy reporting now?
04EvidenceEvery live panel keeps the source and retrieval time visible.
CHOOSE WHAT YOU WANT TO SEE
One coast can be great for one activity and mediocre for another.
Tidepooling
Find unusually low tides that occur in useful daylight, then check live swell and weather before going.
Coastal photography
Rank tide extremes that overlap sunrise, sunset and favorable short-range weather windows.
Big-wave viewing
Watch live buoy wave height and period without turning a viewing signal into a surf-safety claim.
Wildlife pulse
Use recent public marine-mammal observations as a recency signal, never as a promise that animals will be present.
Beach day
Combine NWS weather, wind and live water context into a planning score, with official alerts kept visible.

Browse all locationsSOURCE DISCIPLINE
Fresh when it is fresh. Partial when it is partial.
If NWS, NOAA, a buoy or a wildlife feed is unavailable, the interface says so. A missing source never becomes a favorable score by default.
- Forecast is not presented as observation.
- Current buoy data is not projected 7 days forward.
- Wildlife reports are not abundance forecasts.
- Rarity is local to a station and time window.
- Safety and closures remain official-source decisions.
