Is it warm enough for swimming?
Water temperatures can vary significantly based on the location and time of year. Generally, swimming is considered comfortable in water temperatures between 78°F (25°C) and 82°F (28°C). Cooler temperatures can be refreshing, but if the water temperature drops below 70°F (21°C), prolonged exposure can be uncomfortable without a wetsuit.
Should you wear a wetsuit?
Wetsuits provide insulation and buoyancy, making them ideal for swimming in cooler waters. Here are some general guidelines for wetsuit use:
- 70°F (21°C) and above: No wetsuit needed for most people.
- 65°F - 70°F (18°C - 21°C): A thin wetsuit (2mm - 3mm) is recommended.
- 60°F - 65°F (15°C - 18°C): A thicker wetsuit (4mm - 5mm) is recommended.
- Below 60°F (15°C): A full wetsuit with a hood, gloves, and booties is recommended for safety and comfort.
