Conditions at Nusa Dua in August
August: Zero Percent is a Low Blow
August is the cruellest month. The average swell is a solid 7-8ft (2.1-2.4m) at 14.4s, and the SSW direction accounts for 49.7% of the spectrum - enough to make any surfer salivate. But the ideal wind score drops to 0%, the only month all year. ESE winds blow 52.4% and SE 36.9%, with a thick 10-30kph flow that churns the ocean into a cross-shore mess. Even the biggest S/SSW sets are rendered bumpy and closed out. Water temperature is at its annual minimum of 26.5°C, air at 25.5°C, and precipitation is just 0.65mm/day - the driest month. It's still a swell factory, but wind remains the enemy.
