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.

In May, Big Rock offers surfers consistent but generally small to medium-sized waves with an average swell height of 1.2m and a decent period of 7.5s, providing some energy for decent rides. The majority of waves come from the S to SSE direction (peaking in the 1-1.5m range), with occasional larger sets up to 2.5m. The ENE and ESE directions contribute slightly stronger but less frequent swells. Wind conditions are variable, with only 18% of the time offering ideal offshore or light cross-shore breezes for surfing. The predominant winds come from the S to SSW, often in the 10-30kph range, which can create choppy conditions. While not the most powerful month, May delivers rideable waves for intermediate surfers, especially when winds cooperate. Early mornings may provide the cleanest sessions before onshore winds pick up.
