Finnimas seasonal overview
Best Surf Season (December - March)
The heart of the North Indian Ocean winter brings a powerful shift in atmospheric dynamics, and Finnimas reaps the rewards. During these months, the strong NE monsoon establishes itself, delivering a consistent stream of offshore winds from the N, NNE, and NW quadrants. Combined with a healthy mix of long-period groundswells from the S, SSW, and SSE, this creates the most reliable and high-quality surf of the year. March stands out as the absolute peak, with a staggering 77% of swell coming from optimal directions and a remarkable 65% of days blessed with offshore winds. Expect punchy 1-1.5m waves on average, with occasional larger pulses, and wave periods regularly reaching into the 12-second range.
Fair Surf Season (April & November)
These transitional months offer a mixed bag. April sees the tail end of the optimal swell window, with strong S and SSW swells still rolling in, averaging 1m at 12-second periods. However, the wind picture becomes murky as the NE monsoon weakens and westerly flows increase, resulting in only about 51% offshore conditions. November marks the return of better conditions, with offshore winds climbing back to 48% and a more diverse swell spectrum, including the return of SSE and S groundswells. These months require a keen eye on the forecast – when the wind aligns, the waves can be excellent.
Low Surf Season (May - October)
The SW monsoon dominates from May through October, creating a challenging environment for Finnimas. While the swell is not absent – in fact, average wave heights increase to 1.3-1.5m with long 12-second periods – the wind is almost consistently onshore from the SW, W, and WSW. This aligns with the onshore directions at the break, meaning the majority of days are blown out with choppy, messy waves. The best chances during this period come from a fleeting weather window when a tropical disturbance passes to the north or a high-pressure system briefly nudges the winds northerly. July and August offer slightly higher offshore wind percentages (around 34-35%), but conditions remain marginal overall.

Conditions at Finnimas in September
September: Monsoon Lingers, Swell Fades
September sees the SW monsoon beginning to weaken, but the effects linger. Offshore wind remains at 35%. Swell from the optimal directions totals 65.2%, with the SSW (34.3%) and S (25.3%) leading the charge. The average wave height drops slightly to 1.3m, and the period is 11.5s. Wind from the W (26.0%) is still the dominant player, but the NW (6.0%) and WNW (17.5%) directions increase, offering more windows of cross-to-offshore conditions. The swell height is mostly in the 1-1.5m range, producing fun-sized waves. When a northerly wind event occurs, the waves can be clean and rippable. September is the beginning of the transition back to better conditions, but still a month of inconsistent quality.
