Swimming in the ocean when the outside temperature is between 60-70 degrees Fahrenheit can be quite cold, especially if you're not accustomed to lower water temperatures. Water takes longer to warm up and cool down compared to air, so even if the air temperature is in the comfortable range, the ocean water may still feel chilly.
The perception of coldness also depends on factors such as wind speed, humidity, and personal tolerance to cold. Additionally, different individuals have varying levels of cold tolerance, so what feels cold to one person may be tolerable or even enjoyable for another.
If you plan to swim in the ocean within that temperature range, you may want to consider the following:
Duration of exposure: Prolonged exposure to cool water can lead to discomfort and increased risk of hypothermia. Keep your swimming sessions shorter if the water is colder.
Protective gear: Wearing a wetsuit or a rash guard can help insulate your body and provide some protection against the cold water.
Acclimatization: Gradually expose yourself to cooler water temperatures to allow your body to adjust and become more comfortable over time.
Safety precautions: Always prioritize safety when swimming in the ocean. Be aware of your surroundings, tides, and currents. If you're not a strong swimmer or unfamiliar with the area, it's best to swim in designated swimming areas and follow any local guidelines or warnings.
Ultimately, whether swimming in 60-70 degree Fahrenheit water feels cold to you will depend on your personal preference, cold tolerance, and the specific conditions on the day of your swim.
