About
Plan your next UK beach day with tide times that work offline. Check the next high or low tide, follow the countdown, and browse seven days of forecasts free, with no advertising.
Open CoastClock to your chosen reference gauge and see whether the tide is rising or falling, a 24-hour relative tide curve, and the day’s high and low tide events. Useful for planning beach walks, fishing trips, paddling and time by the sea.
PLAN OFFLINE
Core harmonic predictions work without a connection, so you can review tide times before leaving home or when coastal reception is poor. Free planning covers seven days; CoastClock Pro extends the date range to 365 days.
HONEST UK COVERAGE
Choose from 45 named UK reference gauges derived from the CC BY 4.0 TICON harmonic dataset, with names sourced from NTSLF/BODC. CoastClock always shows which reference gauge you selected. It does not pretend every beach is a separate measured station.
OPTIONAL LIVE CONTEXT
Where a matching gauge is available, CoastClock shows the latest Environment Agency real-time tide observation, its timestamp, datum, and stale status. If the live service is unavailable, your offline forecast remains available.
BUILT FOR COAST DAYS
Search a map and list, match your nearest supported gauge on device, save favourite places, add the next tide to your Home Screen or Lock Screen, and schedule high- or low-tide alerts with Pro.
