Conditions at Airport in August
August: The Consistency King
August keeps the pedal down. Average swell height remains at 7ft (2.2m), period is still 14.4s, and the direction shifts a little more toward SSW (49.7%), while S accounts for 24.3% and SSE for 5.3%. The SW component remains tiny, so this is still a south-based groundswell, but the SSW weighting is slightly better for wrapping into the west-facing beach. This is one of the most consistent months of the year: 5-8ft (1.5-2.5m) waves dominate, and there is even a touch of 8ft-plus (2.5m-plus) energy from the SSW direction.
The trades remain locked in with ESE at 52.4% and SE at 36.9%, and the ideal-wind score improves to 57%, as more of the offshore flow sits in the moderate 10-20kph bracket compared with July. Water temperature dips to its annual minimum of 26.7°C, still perfectly warm for boardshorts, while rainfall is nearly nonexistent at 0.72mm/day. August is prime-time Airport: powerful, clean and remarkably consistent.
