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.

December at Big Rock offers consistent surf with an average swell height of 1.2m and a decent period of 7.1s, providing rideable waves most days. The dominant swell direction is ENE to E, with the largest proportion of waves falling in the 1-1.5m range (19.65% ENE, 15.88% E), offering clean, manageable conditions for intermediate to advanced surfers. Smaller but still surfable waves (0.5-1m) are frequent, while overhead waves (2m+) are rare but present occasionally. Wind conditions are less favorable, with only 2% of days having ideal offshore winds. The predominant winds are NNE to NE (often 10-30kph), which can create choppy onshore conditions, though lighter winds occasionally occur from the E or ESE. The best sessions will likely coincide with ENE swells and lighter winds, but surfers should expect variable conditions with frequent cross-onshore breezes. A solid spot for those comfortable with mid-sized waves, though wind management is key.
