Over 9,900 lakes, rivers and beaches in 64 countries, from 46 official and open sources. Where a monitoring network measures, you get the real value – with history.
Brr – or bliss? BrrChecker tells you how warm the water really is before you risk your big toe.
Current water temperatures for over 9,900 lakes, rivers, lidos and coastlines in 64 countries – from 46 official and open sources: national monitoring networks, buoys, health-authority samplings and, where no gauge exists, vetted lake models.
THE PERFECT PLUNGE
• Widget with temperature and trend on your Home and Lock Screen – and on Apple Watch
• History curve: did the sun deliver, or did the rain spoil it all?
• Temperature alert: BrrChecker pings you when your water hits your target temperature
• Favorites for your swimming lake, river spot and after-work dip
• Tides for coastal spots: high and low water at a glance
THE BRRSCORE
From 1 to 10, for seven sports: swimming, SUP, kayaking, surfing, windsurfing, kitesurfing and pump foiling. Wind, waves and water temperature combined – plus a wetsuit recommendation and a cold-water profile for those who mean it.
VACATION WHERE IT'S WARM
Filter by target temperature and discover the warmest spots from the Mediterranean to the Caribbean. "Show me water above 24 °C" – and your next destination is set.
SWIM CLEAN
Official EU bathing-water classification, bacteria levels and – where authorities provide them – blue-green algae warnings. Official swimming bans are always visible, even without Pro.
FROM ICE BATH TO BATHTUB WARM
Whether it's 4 °C for the winter-swimming kick or 26 °C for a family day – BrrChecker knows both worlds. The name says it all.
STRAIGHT FROM THE LIDOS
Lidos can maintain their own listing: opening hours, admission, special notes – and, if they like, the temperature of individual pools.
Data-minimal: no personal data, no accounts, no ads.
Get BrrChecker – check first, then dive in.

Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
Pit stop! New head gasket, fresh gearbox oil, tab shifter realigned — the detail page glides like freshly oiled again. Patched along the way: the wiewarm.ch link on lido pages led nowhere.
