Finnimas - surf spot statistics

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.

December: NE Monsoon in Full Swing

December sees the NE monsoon fully established. Offshore wind is at 55%, with strong NE (16.7%) and NNE (9.8%) winds providing clean, offshore conditions. Swell from the optimal directions (SE, SSE, S, SSW) totals 45.9%, with the S and SSW at 26.1%. The average wave height is 1.1m, and the average period is 8.9s. The swell is a mix of shorter-period E and ENE swell (14.2% from E/ENE) and longer-period S and SW groundswell. The NE wind creates a clean surface, and the swell from the south still wraps in with decent energy. Expect fun-sized, head-high waves most days, with occasional larger pulses when a Southern Ocean storm aligns. December is a reliable month for good surf, setting the stage for the peak season ahead.
