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.

September at Big Rock offers generally manageable surf conditions with an average swell height of 1.0m and a solid period of 8.9s, suggesting consistent, well-formed waves. The majority of swells come from the SSE to S directions, with the most frequent wave heights falling between 0.5-1.5m, making it suitable for intermediate surfers. Larger swells (1.5-2.5m) occur occasionally but are less dominant. Wind conditions are variable, with ideal offshore or light cross-shore winds (favorable for surfing) present 37% of the time. The dominant wind directions are SSW to SW, often blowing at 10-30kph, which can create choppy conditions if onshore. Expect a mix of clean and slightly textured waves, with the best sessions likely when winds ease or align favorably. While not epic, September provides decent surf opportunities, particularly on days when swell and wind align properly.
