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.

January at Big Rock offers fairly consistent surf with an average swell height of 1.0m and a decent period of 7.1s, making it suitable for intermediate surfers. The predominant swell directions are ENE and E, contributing to the majority of waves in the 0.5-1.5m range, with occasional larger sets up to 2.5m. However, wind conditions are often less than ideal, with only 2% of the time providing clean, rideable conditions. The dominant NE and ENE winds frequently bring choppy or cross-shore winds at 10-30kph, which can negatively impact wave quality. Surfers should target the rare days when lighter winds coincide with the best swell direction (ENE). Overall, it's a spot with moderate potential in January but requires patience for the best sessions.
