Do California Surfers Need Wetsuits Year-Round? No.

False. California surfers do not need wetsuits most of the year.

• Water Temps: 55–65°F (13–18°C) year-round (cooler north, warmer south).
• Summer/Fall (Jul–Nov): 62–68°F (SoCal) – boardshorts/spring suits (1–2mm) common.
• Winter/Spring (Dec–Jun): 54–60°F – 3/2mm or 4/3mm fullsuits typical.
• Exceptions: NorCal (Mavericks, Ocean Beach) colder; booties/gloves/hoods in deep winter.

Many surfers own multiple suits (spring, full, hooded) and choose daily. "Most of the year" in Southern California = trunks or springsuit. The myth likely comes from East Coast or UK surfers visiting.
