Big Rock - surf spot statistics

Big Rock in India is primarily a windswell-dominated spot, with ground swells making a minor contribution throughout most of the year. The best months for surfing are between July and September, when ground swell presence increases slightly (17-27%) and wind conditions improve significantly, with good winds occurring 28-37% of the time. During this period, mean swell size remains consistent at around 1.0-1.1m, offering more rideable waves. August stands out as the most favorable month, combining a 23% ground swell contribution with the highest likelihood of good wind conditions (30%). Outside this window, the spot suffers from predominantly poor wind conditions (70-98% bad winds), particularly from November to February, effectively making winter months nearly unsurfable due to strong onshore winds and minimal ground swell. While May and June see a slight uptick in swell size (1.2m), wind conditions remain suboptimal (79-82% bad winds). For consistency and cleaner conditions, late summer (July-September) is the clear choice, despite the generally small swell size. Advanced surfers may find occasional workable days in April-May or October, but the spot heavily relies on local windswell and requires patience outside peak season.

February at Big Rock offers surfable conditions, though they are generally small and inconsistent. The average swell height is 0.8m with a decent period of 8.1s, providing some clean, rideable waves, particularly when combining ENE to SE swell directions. Most waves fall in the 0.5–1.5m range, with the highest frequency coming from SSE (27.89% in 0.5–1m). Larger waves above 1.5m are rare, occurring mostly from NE, ENE, and E directions. Wind conditions are less favorable, with only 6% of days being ideal—typically when lighter ENE or E winds (<20kph) align with the swell. However, stronger NE to ENE winds (10–30kph) dominate, often creating choppy or cross-shore conditions. For the best sessions, watch for days with ENE swell and lighter winds, but expect predominantly small, weak waves with occasional medium-sized peaks when conditions align.
