The coastguard says it will have all volunteers out today as they predict a rise in incidents on what could be the UK's hottest day of the year so far.
Across South Devon and East Cornwall there will be 200 volunteers working with around 30 of those giving out safety advice to stop people falling into difficulty.

It comes as The RNLI charity is reintroducing all its lifeguard patrols across the South West's beaches as the weather heats up again.

Over the next two weeks they'll restart patrols on around 30 beaches - some have already been ongoing since the start of June.
