How warm should beach water be?
How warm should beach water be? It's more of a question of preference. A little cooler than your body temperature (98.6° Fahrenheit) should not be too cold so that you don't get chilled. 70° to 78° Fahrenheit is the range where most folks feel comfortable swimming.
Can you swim in 10 degree water?
Yes you can swim for a short time in water temperatures from 10 to 15 degrees without a wetsuit but you will be cold and you will get colder when you get out. If you are not acclimatised to the cold water, you will probably need a wetsuit for temperatures below 15 degrees until your body gets used to the cold water.
