During a safety check, what should you do if you determine that the water temperature of the lake is very cold due to a recent storm?

When the water temperature is very cold, especially after a recent storm, it's crucial to prioritize the safety of the swimmers. Alerting swimmers to the cold water allows them to be aware of potential risks such as hypothermia, which can develop when the body loses heat faster than it can produce it. By watching for signs of hypothermia, lifeguards can respond quickly if someone begins to show symptoms such as shivering or confusion, ensuring that immediate assistance is provided if necessary.

This approach actively engages and informs the swimmers, helping them make better decisions about entering the water while the lifeguard maintains vigilance over their well-being. Promoting awareness is essential in such conditions, as it allows swimmers to take precautions to protect themselves and potentially avoid dangerous situations.
