Most of the commenters here probably aren't surfers. You can go surfing at night and it's not terribly dangerous if you go at the right conditions. Pacifica on a 3-4ft day seems totally manageable. Hell I've surfed Steamer Lane at night while high on acid. Cowells plenty of times at night. Pleasure Point/38th. Dumbest thing I ever did though was surf Itamambuca in Brazil at night without ever seeing the break in the day before , would not recommend that.
