Five Islands seasonal overview
Best Surf Season (December - March)
The northeast monsoon sets the stage for the best surf of the year at Five Islands. From December through March, the SE-facing reefs see clean, consistent E/ESE/SE/SSE swell averaging 3-4ft (1.1-1.2m), with periods lifting from 9.4s to 10.6s as the season matures. The wind story is the real key: ideal offshore flow from the W-NW quadrant is present 48-58% of the time, giving the swell a groomed, rippable texture. This is the window when the combination of size, period and clean wind aligns most often.
Fair Surf Season (April, October - November)
The transition months offer a trade-off. April still has 56% ideal wind and the longest average period of the year at 10.9s, but the swell angle swings south toward SSE/S/SSW, making the exposure less direct. October and November are the reverse: the southwest monsoon is weakening, southwest and west winds begin to dominate, and the swell remains solid at 4-5ft (1.4-1.5m), but ideal wind percentages only reach 38-45%. These months can produce great sessions, but consistency is lower than the core winter months.
Low Surf Season (May - September)
The southwest monsoon roars to life in May and dominates through September. This is the season of maximum swell height - 5-6ft (1.5-1.8m) on average with long 10.5-10.9s periods and plenty of 2m+ sets - as Southern Hemisphere storms fire up. However, the wind quality collapses: ideal offshore wind drops to just 32-40%, and the ESE/SE/SSE onshore flow puts chop and bump on the surface at a spot that really needs that W-NW offshore breeze. June, July and August are especially rough; May and September are slightly better but still far from the dreamy consistency of the northeast monsoon.
