About NippyIndex

NippyIndex is a free tool that describes water and weather conditions at more than 1,700 UK coastal and inland locations. It brings together interpreted data from meteorological, marine, tidal and bathing-water sources so that swimmers, dippers and paddlers can see, in one place, the factors that shape conditions at a spot they know.

It describes conditions only. It never says whether a location is safe or suitable, and it makes no assumptions about anyone's ability or experience. You can read more about the data and methods behind it on the How NippyIndex works page. NippyIndex is part of NippyDips, a small UK shop for wild swimming gear.

Get in touch

We would love to hear from you. Email is the best way to reach us:

Please write to us about anything, including:

• Questions about the project, the data it uses, or how a score is worked out.
• Problems and errors, such as a location in the wrong place, a name spelt wrongly, a value that looks implausible, or a page that does not load.
• Suggestions, such as a location you would like added or an idea for making the site clearer or more useful.

Reporting a problem

If you are reporting something that looks wrong, it helps us a lot if you can include:

• the name of the location, or a link to its page;
• what you saw and what you expected to see;
• roughly when you looked (date and time).

We take accuracy seriously and would rather show nothing than show something misleading, so reports like these are genuinely valuable. We are a very small operation, so replies may take a little while, but every message is read.
