The council wants residents to resist the urge to swim in open water in the borough, such as the canal or Newbold Quarry as it can put them, or others, in danger.
Tom Kittendorf, Rugby Borough Council, Chief Officer for Leisure and Wellbeing, said: “We understand the temptation to cool off on a hot day, but the reality is if you do this you could be putting yourself and your friends in serious danger.
"Newbold Quarry is incredibly deep in places, and the water can be freezing cold.
Even the most experienced swimmer can get caught in obstructions or suffer cold water shock."
Residents who see someone in trouble should not enter the water but call 999. It can help emergency response teams if residents are able to provide their What3Words location, which can be found on the What3Words App.
