Is 70 Degrees Outside Too Cold to Swim?
You can swim comfortably when it’s 70 degrees outside, but remember water often feels colder because it retains less heat than air. Your body loses heat faster in water, especially if it’s cool or windy, which might make you feel chilly sooner.
Wearing a wetsuit and staying active helps keep you warm. Feeling cold or numb means it’s time to get out. Keep in mind, there’s more to think about for a safe, warm swim in these conditions.
