Lifeguards have been stood down during the pandemic as the RNLI could not guarantee they would be able to carry out their duties in a safe and socially distanced manner.
After restrictions began to be eased in May, lifeguard patrols were gradually reintroduced at 100 busy beaches.
From July 4, another 60 beaches across the country will have their lifeguard cover reinstated.
These include Runswick Bay, Scarborough North Bay and Filey, with lifeguards returning to Sandsend on July 11. Patrols began at Saltburn, Whitby, Scarborough South Bay and Bridlington South in June.
Two beaches in the Scarborough area that would normally have lifeguard cover, including Cayton Bay, will remain unstaffed.
Lifeguards will now wear PPE and will not be able to deal with all minor first aid cases, although they can advise on self-treatment. They will also maintain a safe distance from beach-goers during patrols.
RNLI staff admit that this summer could be the charity's 'biggest ever' due to restrictions on foreign travel.
Lifesaving manager Darren Lewis said:
"With schools not yet fully open and restrictions on travel, we know that this could be the busiest summer ever for both our lifeguards and our lifeboat crews. I want to thank all those lifeguards who have already started their patrols or are now preparing to get back on the beach - they know this will be a challenging summer and are doing a brilliant job helping to keep the public safe during this pandemic.
"We must all continue to be aware that the risks from the pandemic have not gone away, but if people work with us and the other emergency services by following social distancing and other government guidance, we hope to be able to continue to provide lifeguard services this season. I’d like to thank all our partners - from the Coastguard, to local councils and landowners - who are also working hard to help us patrol as many beaches as possible."
Beach users are reminded to check local weather forecasts and tide times, keep a close eye on people in the water, ensure children do not swim alone, and avoid using inflatables to ensure safety at sea.
In an emergency, dial 999 and ask for the Coastguard.
