Conditions at Orrua in August
August: Warm Water, Small Lines
August is a near twin of July, but with the warmest water of the year. Average swell height stays at 1.0m (3ft) and the period edges up to 9.2s. The NW swell lobe is again enormous at 65%, with WNW and NNW each delivering around 16%. These small, crumbly lines are consistent but lack the power and depth needed to make Orrua truly pump. Ideal offshore winds improve only slightly to 22%, and S/SSW winds remain scarce at around 5.5%. The wind rose is dominated by the N to NNW sector, meaning the surf often comes with surface chop and bump. Water temperature peaks at 22.5°C, air averages 21.1°C and rain is minimal at 1.40 mm/day. August is for warm-water fun rides, not heavy sessions.
