Yo-Yos - surf spot statistics

Yo-Yos in Indonesia is a consistent year-round surf spot with a strong reliance on ground swells, which dominate throughout the year, rarely dropping below 90% presence. The swell size averages between 1.4m and 2.0m, peaking from June to September with the largest waves (1.8m–2.0m). However, wind conditions play a crucial role in surf quality here. The best months for favorable wind conditions are February (38% good winds) and January (30% good winds), despite still having a majority of bad wind days. From May through December, wind quality deteriorates significantly, with the worst conditions from July to October (only 8–11% good wind days). While the swell is reliable in size and consistency, the onshore winds make the peak swell season (June–September) less ideal unless you catch rare clean days. If you prioritize cleaner conditions over sheer swell size, January and February offer the best balance with manageable winds and solid 1.5m–1.6m swells. For advanced surfers willing to gamble on wind luck, the bigger June–September swells can deliver epic sessions, but expect mostly challenging wind-affected waves.

April at Yo-Yos delivers consistent surf with an average swell height of 1.5m and a solid 14.4s period, providing powerful, well-spaced waves. The swell predominantly arrives from the SSW and SW directions, with the majority of waves falling in the 1-2m range—ideal for intermediate to advanced surfers. About 30% of the time, waves reach 1.5-2.5m, offering more challenging conditions. Wind is a mixed factor: only 29% of the time is it favorable for surfing, mostly light easterlies (10-20kph). However, stronger ESE and SE winds (20-30kph) occur frequently, potentially creating chop. Cross-shore or light offshore winds are rare, so patience is key for clean sessions. Overall, expect decent waves but variable wind conditions, with the best sessions early morning before winds pick up.
