Everyone knows that to find decent surf you have to drive north to Sebastian Inlet or fly south to Barbados. Locally the crowds congregate around First and Second streets in Miami Beach. But the truth is that nothing breaks along South Florida beaches without a storm swell. And when there is a strong swell -- especially from the northeast during winter -- you should check out 23rd Street, right in front of the Roney Plaza. A somewhat-permanent sandbar approximately 30 yards offshore pumps up a northeast swell something sweet. We've seen it overhead and hollow at the same time First Street is undifferentiated mush -- make that undifferentiated mush with way too many people in the water.
