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.

July at Big Rock delivers modest but surfable conditions, with an average swell height of 1.1m and a decent 8.9s period, suggesting relatively clean and organized waves. The swell direction is dominantly from the SSE to S (totaling ~75% of occurrences), producing waves in the 0.5-2.5m range—ideal for intermediate surfers when combined with the period. However, wind conditions are hit-or-miss: only 28% of the time are they favorable (typically light offshore or sideshore from the N-NE). The bulk of winds blow from the SW-WSW (often 10-30kph), which can create chop, especially when stronger (20-40kph winds occur ~30% of the time). Expect smaller, weaker waves early in the swell window (E-ESE) and more punchy, rideable waves from the S-SSE. The spot works best on SSE swells with lighter winds, but patience is key—consistent quality requires timing the rarer clean wind windows.
