Cimaja - surf spot statistics

Best Surf Season (December - March)

The Northwest Monsoon roars to life from December through March, delivering the highest percentage of offshore winds from the N to NW quadrant. During these months, the Indian Ocean churns out consistent SSW and S groundswell with average wave heights of 1.4 meters and periods exceeding 12 seconds – providing powerful, clean, and rippable waves. This is the prime window for world-class surfing at Cimaja, with glassy mornings and groomed lines that keep you in the water all day.

Fair Surf Season (April & November)

April and November act as transitional shoulders, where the wind patterns are shifting. In April the southeast trades start to build, dropping ideal wind to 35%, but the swell period peaks, offering long, powerful lines. November sees the trades relax and the northwest monsoon return, with ideal wind around 15% but increasing. Surf quality becomes more variable – expect clean dawn sessions mixed with afternoon onshore chop.

Low Surf Season (May - October)

From May through October, the southeast trade winds dominate the region, blowing steadily from the E to SE and ruining wave quality. Despite the largest and most powerful swell of the year – average heights from 1.6 up to 2.0 meters and periods over 14 seconds – the wind rarely blows offshore, with ideal conditions dropping below 10% in the peak months of June through September. The ocean is pumping, but the surface is often bumpy and difficult. This season is for the dedicated few who can find the brief windows of clean offshore flow.

April: Longer Periods, Less Reliability

The swell quality peaks in April with an average period of 13.7 seconds – the longest so far. Swell from due south becomes more prominent, adding a different angle to the lineup. However, the northwest monsoon retreats, and the wind shifts to a more easterly and southeasterly flow. Only 35% of the time are conditions ideal, meaning you have to pick your windows. Early mornings and late evenings can still offer clean lines, but the trade-off for that extra long-period power is more windswell interference.
