The conditions shown here are calculated by this tool from third-party forecast models, not measured at each location, and can be incorrect or understate what is actually happening. Open water can change fast and without warning.

• Nippy Index is an assessment of physical conditions only - not a safety rating
• Always make your own assessment before entering the water
• This is not a substitute for official forecasts, warnings or lifeguard advice - check local signs and current alerts
• A location appearing here does not mean it is safe, accessible or suitable for any activity
• The Nippy Index describes conditions only. It does not rate or imply safety, and does not account for your individual ability

Open water swimming carries inherent risks. You are responsible for your own decisions and your own safety - this tool informs, it does not decide for you.
