The UK has one of the largest tidal ranges in the world and tides can rise several metres in just one hour. Tidal flow varies in speed too. This is something that catches people out every year, especially on unfamiliar beaches.
At Crantock, tides deserve extra respect and with spring tides coinciding with the Easter bank holiday weekend, conditions will be more extreme than usual.
Here’s what to know:
• Tides can change fast – areas that feel wide and safe at low tide can disappear quickly
• The Gannel Estuary is particularly dangerous before and after high tide, water rushes in and out at speed
• Strong currents aren’t always obvious – especially on calm-looking days. In fact, apparently calm water can actually be caused by a rip current.
• Risk of being cut off – sandbanks, estuary crossings and exit routes can vanish on big tides
• Storms and swell increase the danger making water faster and less predictable
• Winter = no lifeguard patrols – you need to manage your own safety
Before heading out:
✔️ Check tide times
✔️ Plan your route and exit
✔️ Avoid crossing the estuary near high tide
✔️ If unsure, turn back early
Tides are powerful, fascinating and unforgiving if underestimated. A quick tide check can make the difference between a great day out and a dangerous situation.
If someone (or a furry friend) gets cut off or into trouble: Do not enter the water to try and rescue them. You put yourself at serious risk and may become another casualty.
Instead, call 999 and ask for the Coastguard. They are trained and equipped to respond safely.
