Burnham's lifeboat crews rescued 67 people last year.
The boat was launched 44 times in what was a busy year for the volunteer crews across East Anglia.
Peter Dawes, regional operations manager for the RNLI, said: “Whether it is hot and sunny or windy and rainy, the water always presents a number of risks for visitors to the coast.
“We would always recommend that people take care when going to the coast and follow some simple safety tips; always check tide times before taking to the water.
“Avoid areas where you could get swept off your feet in stormy weather, and if you’re visiting the coast, be sure to visit a lifeguarded beach during the summer months.”
