195 views

The need for a wetsuit is largely dependent on water temperature and personal tolerance to cold. Generally, you might need a wetsuit when water temperatures drop below 70°F (21°C). For temperatures between 62°F (16.5°C) to 77°F (25°C), a thinner wetsuit (2mm - 3mm) is sufficient. Colder waters below 60°F (15.5°C) typically require thicker wetsuits (4mm - 5mm or more). Always consider your own cold threshold and the activity’s duration when selecting the appropriate wetsuit thickness.
