Northern California’s water commonly calls for a 4/3 mm full suit in milder conditions and a hooded 5/4 mm for colder winter sessions. A suit must fit snugly without restricting breathing or paddling; seams, entry system and a hood matter as much as thickness. These current options span everyday 4/3s and warmer hooded 5/4s. Cold-water immersion can become dangerous quickly, so assess conditions, duration, wind, experience and local advice rather than treating any wetsuit as hypothermia protection.

Buying tips
- Use a 4/3 as the baseline for roughly 55–62°F water and consider a hooded 5/4 below that or for long, windy winter sessions.
- A properly fitted suit has no large water pockets at the lower back, crotch or shoulders; try paddling and squatting before removing tags.
- Booties, gloves and a separate hood can be essential in cold conditions, but they do not replace sound judgment about currents, surf, daylight and a reliable exit.
