Falmouth Coastguard has issued this statement:
We have spring tides at the moment that come in faster and further than usual. For this reason people out and about enjoying the Cornish coastline need to be especially careful to plan their trip.
Always check the weather and tide timetable before you set out on your walk and wear appropriate clothing for the unseasonably cold weather. If you do get cut off call 999 Coastguard.
