Beach water temperature FAQ
Where is the warmest ocean water in the US right now?
Right now the warmest beach water in our catalog is 86°F at French Leave (The Bahamas). South Florida, the Florida Keys, the Gulf Coast and Hawaii hold the warmest water through the summer — this page ranks all reporting beaches live, updated several times a day.
Where is the coldest beach water in the US right now?
The coolest reading in our catalog right now is 59°F at Nauset Beach (Cape Cod). Pacific Northwest, Northern California and New England beaches run coldest year-round — even in summer the open Pacific and North Atlantic stay bracing.
Is US beach water warming or cooling right now?
Across 215 reporting beaches, water temperatures have held roughly steady on average over the past seven days. The fastest-warming water this week is Carmel Beach (Central Coast California), up 5°F. The trend arrows on the map and leaderboards show each beach's own seven-day change, and the selected-beach card adds a past-week and forecast sparkline.
How do I find the water temperature at the beach closest to me?
Use the Find my nearest beach button above the map — with your permission it locates the closest beaches in our catalog and shows their live readings and distances — or type any beach into the search box. Every beach also has its own guide page with live water temperature, surf, tide and UV, updated through the day.
What is a comfortable water temperature for swimming?
Most swimmers find 78–85°F (26–29°C) ideal — warm enough to stay in for a long time without a wetsuit. From 70–77°F the water feels refreshing but comfortable for active swimming; 60–69°F is bracing and most people want a wetsuit; below 60°F is cold-plunge territory where you should limit your time in the water.
How is beach water temperature measured, and how accurate is it?
The readings here are sea-surface temperature at each beach's exact coordinates, from Open-Meteo's marine model (satellite observations blended with a numerical ocean model). It reflects the open water just offshore. Nearshore water over a shallow, sandy bottom can run a couple of degrees warmer than the offshore reading on a sunny afternoon, and a couple cooler right after an upwelling or a cold front, so treat it as a close estimate rather than a thermometer at the waterline.
Which US beaches have the warmest water year-round?
The Florida Keys, Southeast Florida (Miami, Fort Lauderdale, Palm Beach), the Gulf Coast of Florida and Hawaii stay the warmest across the whole year, rarely dropping far below the mid-70s even in winter. The Caribbean and Bahamas beaches in our catalog are warmer still.
How often do these water temperatures update?
The whole catalog refreshes several times a day. Every beach's home page also shows its own live water temperature, surf, tide and UV, and the Conditions page adds a 10-day outlook.
Water temperatures are live sea-surface readings from Open-Meteo marine data for each beach’s exact coordinates, refreshed several times a day. Nearshore water over a shallow sandbar can run a couple of degrees warmer than the open-water reading on a sunny afternoon.
