You'll mostly need lighter gear, like a 6-weight rigged with either an intermediate or a sinking line. Most fish hold deep this time of year; even the bonito and mackerel make few surface appearances, so you need to get down to them. In addition, a floating line gets washed around far too much in the surf, even in the shallowest conditions. In these situations, your leaders should be short - maybe 4 or 5 feet. For fishing the Southern California beaches, shrimp and surf-crab-type patterns, and small weighted bonefish flies are best. If you do choose to head into the surf you'll need waders and boots with soles made for walking along slippery rocks. Avoid fishing during slack tides and be careful to watch incoming water so that you don't get cut off.
