Conditions at Long Beach in June
June: Small but Well Directed
June brings the lowest average swell of the first half of the year at 4.6ft (1.4m), though periods stay respectable at 11.4s. The wave rose is heavily concentrated in the optimal quadrant - WSW (36.8%) and W (32.3%) are the standouts, with SW adding 15.3% and WNW 5.9% - so the swell that does arrive is well directed. The limiting factor is wind. Offshore NE to ESE flow covers less than 8% of the wind rose, while onshore WNW winds dominate at 36.8% and NW adds another 8%. Ideal conditions fall to just 18%, meaning the wave quality is frequently compromised by summer onshores. Average air temp reaches 12.5°C, water temp 13.5°C, and precipitation is minimal at 2.51mm/day. The days that do align - usually a morning session before the westerly kicks in - can offer clean, fun-sized waves in the 3-5ft (0.9-1.5m) range, but do not expect consistent firing surf. This is a patience month.
