Conditions at Chesterman Beach in August
August: Still Small, Still Windy
August mirrors July with an average swell of 1.2m (3.9ft) and an 11.3s period. The swell window remains dominated by W and WSW, so when the ocean is clean there are rideable, shaped-up waves. However, the northwest Pacific high continues to pump WNW and NW winds across the beach, and ideal surf wind is only 13% of the time. The main difference from July is a subtle increase in variability - there are a few more ESE offshore episodes in the mix, offering slightly better chances for a clean session. Air temperatures reach the year's warmest at 14.9°C, water temp maxes at 14.2°C, and precipitation stays low at 1.99mm/day. Small-wave boards and a patient attitude are required.
