The problem
Outdated blog posts. Forum threads from 2019. A two-hour drive to discover the river is in flood. Wild swimming has never been more popular — the information infrastructure has barely changed since the hiking map was invented.
The solution
Plungespot pulls live temperature readings, flow data, and user-reported conditions for thousands of spots globally. Before you pack the dry robe, you know exactly what you're walking into.
What you get
How it works
Step 1
Enter a postcode, drop a pin, or use location to find every mapped cold plunge and wild swimming spot within your radius.
Step 2
Check live temperature, flow status, safety flags, and the community log from swimmers who were there in the last 24 hours.
Step 3
Make the call with confidence. After your swim, add your own conditions report to keep the data sharp for everyone who follows.

From the community
“I used to rely on outdated forum posts and hope for the best. Now I check the community log before I leave — twice last month it saved me a completely pointless drive.”

“The temperature data is frighteningly accurate. I've verified it against my own thermometer three times. It's within 0.3 degrees every time.”
Tom H.
Cold plunge practitioner, Bristol
“I'm a beginner and was terrified of getting conditions wrong. Having safety flags and recent logs from other swimmers took the anxiety completely out of it.”

FAQ
Where does the temperature data come from?
We combine data from hydrological sensors (Environment Agency, SEPA, and equivalent agencies in 18 countries), historical seasonal models, and real-time community-reported readings from swimmers. Each reading shows its source and age.
How current is the community log?
Active spots are logged multiple times per day during peak season. Each log entry shows a timestamp so you know exactly how fresh the conditions are. You can filter by 'last 6 hours' or 'last 24 hours'.
Is this safe enough to rely on for planning?
Plungespot is a planning aid — it gives you the best available data to make an informed decision. No remote sensor replaces your own judgment on the water. Always check conditions yourself when you arrive and never swim alone.
What types of spots are covered?
River pools, freshwater lochs and lakes, sea pools, tidal swimming spots, and designated cold plunge locations. We don't include private reservoirs where swimming is prohibited.
Is it free?
Plungespot is free for all swimmers. We believe access to water safety information shouldn't cost anything.

The right kit is the difference between a transcendent cold plunge and a dangerous one. This temperature-by-temperature gear guide tells you exactly what to wear for wild swimming in every condition, from summer rivers to winter lochs.
Cold plunging is more than a trend — the physiological and psychological responses it triggers are well-documented and genuinely impressive. Here's what the science actually says happens from the moment you hit the water.
