Conditions at Low Island in August
August: Pre-Autumn Pulse
August remains small, but there is a subtle energy shift. Average swell height is 4.6ft (1.4m), and the period eases to 9.8s, the lowest of the year, so the surf can be a little more average and punchy than long and powerful. The wave rose is again led by WSW (31.7%) and SW (29.5%), with SSW adding 14.1%; there is also a slightly better distribution toward the 4.9-6.6ft (1.5-2m) class than in July. Late-season tropical systems in the eastern Pacific can occasionally inject extra SW/WSW swell, but consistency is still limited by the quiet summer storm track. Winds are variable, with NW/WNW and SE/SSE both common, and ideal offshore wind holds at just 26%. Water temperature peaks at 14.1°C (57.4°F), air temperatures average 13.3°C (55.9°F), and rainfall climbs back up to 6.10mm/day. Keep an eye on tropical storm forecasts for surprise late-summer swells.
