July: Maximum Size, Maximum Selectivity
July is the heavyweight champion at Long Beach. The average swell height peaks at 9.5ft (2.9m) with the longest average period of the year at 12.6s. The SW sector contributes 18.4 percent of the swell, with WSW at 9.8 percent and SSW at 8.5 percent, and there is a distinct surge of waves exceeding 8.2ft (2.5m). Onshore wind is also at its annual peak: NNW at 17.7 percent, NW at 10.7 percent and WNW at 6.8 percent can make the beach ragged and messy. But when the tide aligns with a period of ESE/SE/SSE offshore wind, which happens around 19 percent of the time, Long Beach offers some of the heaviest and most grinding waves of the year. Water temperature is a chilly 15.1C, so winter rubber is essential for any extended session.
