Chickens seasonal overview
Best Surf Season (March - April)
As the northeast monsoon starts to break down in March, the swell direction swings from east-northeast into the SE and SSE. Offshore flow from the N/NW quarter becomes more frequent, and the percentage of clean, surfable wind jumps to 61% in March and 55% in April. That combination is the closest Chickens gets to a 'textbook' window: the wave heights are modest but the lines are clean and the right-south component in the swell is consistently present. Periods sit in the 7-8 second range, so it won't be massive, but for a fun, rippable reef break it can be superb.
Fair Surf Season (August - October)
The core of the southwest monsoon brings the biggest south-swell pulses of the year. During August and September, average swell heights reach 1.1-1.2m (3.6-3.9ft) with periods pushing 8.5-9s, and the S/SSE/SSW sector supplies roughly 50-55% of the wave energy. The catch is that the friction of the monsoon westerlies is also strongest now. Only about 39-40% of the wind is ideal, and the W/SW flow can turn the lineup ragged. When a transient ridge builds in from the south and the wind backs into the NW, Chickens can handle solid 3-5ft (0.9-1.5m) south swell; otherwise expect bumpy and drift-heavy conditions.
Low Surf Season (November - February & May - July)
The low season around Chickens is defined by two separate problems. In November through February, the NE monsoon builds a persistent ENE/E swell train with short 6.5-7s periods; that energy hits the island from the wrong side of the swell window, leaving only tiny percentages of true SSE/S/SW swell. The dry, sunny weather is nice, but the wave quality is inconsistent. The other trough is May through July, when the southwest monsoon is raging: S/SSW swell is present, but the wind is onshore or cross-shore over 70% of the time in May and June. Combine that with heavy rain and stormy skies, and you get a lot of bumpy 3-4ft (0.9-1.2m) slop, redeemed only by occasional late-July windows when the wind backs to the NW.
