Good to know
How often are these US readings updated?
NOAA buoys typically report hourly, USGS river gauges every 15–60 minutes and state networks at their own pace. Right now the warmest measured US spot is Golf von Mexiko at 33.0°C.
Are these measured or estimated temperatures?
Measured. Every value comes from a physical station and shows its measurement time. Where nothing measures, we say so instead of guessing.
What about beach water quality?
Over 250 US beaches carry their official EPA annual water-quality rating in the free BrrChecker app, alongside the temperature.
Every spot above is a real measuring station — and there are 12,000+ more in 80 countries, live in the free BrrChecker app. Water temperatures are always free.
