For planning a coast day

Get the tide information you need at a glance.

Open on your chosen gauge

Save a supported UK reference gauge and see the next-tide countdown, direction, high, low, and daily events together.

Plan without reception

Core harmonic predictions work offline, so you can review the forecast before leaving home or when coastal reception is poor.

Know what the data means

CoastClock identifies its reference gauge and distinguishes the offline prediction from a matching live observation.

Keep the next tide visible

Search the map or list, save favourite places, and add the next tide to your Home Screen or Lock Screen.

Questions

About CoastClock: Tide Times UK

What is CoastClock?

CoastClock is a UK tide times app showing high and low tide forecasts, next-tide countdowns, a relative curve, saved places, and optional live observations.

How many places does it cover?

The current listing describes 45 named UK reference gauges derived from the CC BY 4.0 TICON harmonic dataset.

Does CoastClock work offline?

Yes. Core harmonic predictions work without a connection. Live observations need the relevant online service to be available.

What is included for free?

The free version includes seven-day forecasts, one saved place, live gauge readings where available, and real next-tide widgets with a Pro blur. Pro extends forecasts to 365 days and adds more saved places, alerts, and clear widgets.

Can I use it for navigation or safety decisions?

No. CoastClock is a planning aid and does not provide marine weather, tidal streams, or currents. Use appropriate official information and local guidance for safety-critical activity.
