Kuta - surf spot statistics

Best Surf Season (March – May)

The transition from the wet to the dry season brings Kuta’s most consistent combination of solid, long-period SSW groundswell and reliable offshore winds. With average wave heights hovering between 1.5 and 1.7m and periods often exceeding 13 seconds, the setup is ideal for rippable, powerful surf. The percentage of offshore wind (N, NNE, NE, ENE) peaks in April at 56% and remains high in March and May, meaning clean morning glass-offs are common. This is the window when the entire bay lines up with well-shaped, peeling waves that work from mid-tide through to high tide.

Fair Surf Season (June – August)

The southern hemisphere winter unleashes its strongest groundswell, with average heights pushing 2.0m and periods up to 14.4s. The swell is absolutely pumping—consistent, powerful, and often XL. However, the trade winds strengthen from the southeast (ESE, SE), blowing cross-shore and occasionally onshore, which degrades the surface quality. Ideal wind percentages drop to 20–36%, making it a gamble on wind direction. Early mornings and late afternoons can still deliver clean, heavy waves, especially when a ridge of high pressure nudges the wind toward the north. Expect some chop and current, but also adrenaline.

Low Surf Season (September – February)

This period is dominated by the monsoon transition and stronger onshore flow from the west and northwest. Swell energy remains moderate to good (1.5–1.9m, 12–14s), but the wind is frequently out of the W, WNW, or WSW—all onshore for Kuta’s SSW-facing beach. Ideal wind percentages bottom out at just 17% in September and October. While the Indian Ocean still produces long-period swells, the surface is often messy and choppy. The best chance for clean waves comes during rare southerly swell events coinciding with a brief northerly wind shift. Surf is rideable, but don’t expect perfection.

November: Swell Tapering, Wind Mixed

November sees the swell begin to taper: average height 1.5m, period 13.2s. The swell direction is still dominated by SSW (83.0%) and SW (15.2%), with heights mostly in the 1–1.5m range (43.5% SSW) and a good portion in 1.5–2m (32.6% SSW). The wind improves slightly—ideal wind percentage rises to 21%. The wind roses show a more varied pattern: SE (22.4%), SSE (16.7%), and S (9.9%) are still present, but there is an uptick in lighter winds from the north (N, NNE, NE, ENE) which together account for about 5% of the time, plus some calm sets. This month offers a mix of clean windows and rough days. The swell is still fun and rippable, especially during high tide when the waves steepen up.
