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.

Big Rock in June offers surfable conditions, though with some variability. The average swell height is 1.2m with a decent 7.7s period, providing moderately powerful waves, best suited for intermediate to advanced surfers. The predominant swell direction is from the south (S and SSE), accounting for the majority of wave energy, with the highest frequency in the 1-1.5m range (27.6% S, 19.3% SSE). Larger sets up to 2.5m+ are possible but rare, mostly from southerly directions. Cross-shore or light onshore winds (SSW, SW, WSW) dominate, which can create choppy conditions, but ideal offshore or sideshore winds (SE, ESE) occur only 21% of the time. Wind speeds frequently reach 20-30kph (peaking in SSW/SW directions), which may require patience for cleaner sessions. Expect smaller, weaker waves when swells shift ENE or SE. Overall, June is surfable but inconsistent, with the best days when southerly swells align with lighter winds.
