If you're intent on surfing this right point, your best indicator is Rincon. As soon as it's double-overhead, Hammonds will be on. The wave, which rarely gets bigger than a few feet overhead, improves as it approaches the inside, where an end bowl tends to bend back at you. Since it is so inconsistent, there's a whole crew of style-conscious locals who get their pick of the litter.
