Conditions at Kuta in August
August: Peak Size, Peak Onshore Energy
August is Kuta's bulkiest month on paper - 6-7ft (2.0m) average swell, 14.4s period - and SSW direction dominates at 63%, with S adding 22%. The combination produces powerful, long-interval groundswell that wraps around the island and jacks up on the sandbars. Nearly half of all readings sit in the 5-6ft (1.5-2m) range, and 6-8ft (2-2.5m) pulses account for 35%.
The catch is a relentless southeast trade flow. ESE and SE winds total more than 90% of the wind rose, with many hours in the 10-30kph range, making most days a battle against onshore texture. Ideal wind plummets to 20%. Early mornings and protected corners can still hold, but August is more about size and power than clean, user-friendly waves. Water temperature is at its coolest for the year at 26.5°C, air temps 25.4°C, and precipitation nearly disappears at 0.37 mm/day.
