August: A Tale of Two Winds and a Northern Turn
August is more transitional. The average swell drops to 0.9m (3ft), period shortens slightly to 8.5s, and ideal wind falls to 47%. The swell direction is more evenly spread, with E (19%), ESE (21%), SE (18%), ENE (13%) and NNE (7%) all represented; importantly, that NE/NNE component is the closest thing Kirra sees to an optimal north-quadrant swell. Yet the windrose is split between NNW (14%) and NW (9%) - onshore for the spot - and S (11%)/SSW (9%) offshore flows. This makes August a month of definite windows: pick the S/SW flow days, and the ENE/NNE plus ESE mix can produce surprisingly fun, lined-up waves in the 2-4ft (0.5-1.2m) range. Air temperature averages 18.7°C, water temperature is 20.2°C, and rain is only 1.46mm/day - crisp, dry winter mornings.
