18th Street is a laid-back beach break tucked along Florida's East Coast near Jacksonville Beach, where the Atlantic coastline faces northeast and picks up energy from passing nor'easters and tropical swells. Waves here tend to be punchy and short-lived, offering fun peaks ideal for longboarders and beginners working on their fundamentals. The spot comes alive in fall when hurricane-generated swells push up the coast, delivering some of the best conditions this stretch of Florida's East Coast has to offer.
