Conditions at Manly in August
August: Late Winter, Early Promise
August remains firmly in the low season but shows the first subtle signs of spring. Average swell is 5ft (1.6m), period 9.2s, and ideal wind ticks up to 19%. The swell rose is still S/SSE-dominated, with a meaningful SSW/SW component, so the direction quality continues to improve for west-facing Manly. The wind pattern, however, is unsettled: NNW, W and NW directions are common, and W/SW flow still ruins plenty of sessions. Water temperature is at its annual minimum around 18°C, air temps hover near 14°C, and precipitation is low. Surfers start watching the Southern Ocean more closely because any low that slips far enough north can deliver a clean SW groundswell under a morning offshore. Chances are still slim, but the trend is upward.
