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.

November at Big Rock offers surfable conditions, though with some variability. The average swell height is 1.1m with a decent 7.5s period, providing enough energy for intermediate surfers. The most consistent swells come from ENE (29% of waves in the 0.5-2.5m range) and NE (11.5% in the same range), with smaller contributions from E and ESE. Wave heights predominantly fall between 0.5-1.5m (around 65% of occurrences), making it manageable but not consistently powerful. However, wind conditions are less favorable—only 7% of the time are they ideal for surfing. The dominant winds blow from the NNE to NE (10-30kph, 20-42% occurrence), often creating onshore or cross-onshore chop. Offshore winds (WNW to NNW) are rare (2-4% of the time), but when they coincide with ENE/NE swells, the spot can clean up nicely. Expect tricky wind-swell alignment; patience will be key for scoring glassy sessions. Overall, it’s a month with surfable waves but requires selective timing for optimal conditions.
