Cimaja - surf spot statistics

Cimaja, Indonesia, offers consistent surf conditions year-round with a strong dominance of ground swell, which is ideal for clean, powerful waves. The best months for surfing are January, February, and March, when the swell is reliable (90-97% ground swell) and wind conditions are comparatively favorable, with good wind days occurring 41-53% of the time. During these months, the mean swell size hovers around 1.4m, providing manageable yet fun waves. April and December also see decent ground swell (91-99%) but have higher chances of bad winds (70-69% respectively), making them secondary options. From May through November, swell size increases slightly, peaking at 1.9m in August and September, but wind conditions deteriorate significantly, with bad winds dominating 81-96% of the time, making these months less ideal for surfing despite the larger swells. June stands out as having 100% ground swell but suffers from very poor wind conditions (83% bad winds). Overall, the early months of the year (January-March) provide the most balanced combination of quality swell and manageable winds, making them the prime time for surfers at Cimaja.

August at Cimaja brings consistent and powerful surf, with an average swell height of 1.9m and a strong swell period of 15.1s, indicating well-formed, clean waves. The dominant swell direction is from the SSW to SW, with the best waves in the 1.5-2.5m range (over 56% of the time). This often creates high-quality, peeling waves suitable for intermediate to advanced surfers. However, the wind is a limiting factor—only 4% of conditions are ideal, with the majority of winds blowing onshore from the SE to ESE at 20-30kph, which can cause chop and reduce wave quality. Expect occasional larger sets (over 2.5m, ~0.6% of the time) for those seeking more challenging rides. Early mornings or rare wind lulls offer the cleanest sessions, but overall, August delivers decent swell with variable wind conditions.
