Inside Lefts - surf spot statistics

Best Surf Season (May - June)

As the monsoon transitions, the Indian Ocean roars to life. During these months, the average swell height climbs to a solid 1.7-1.8m and periods elongate to 14+ seconds, delivering powerful, long-period groundswells from the SSW and SW. More importantly, the wind regime becomes increasingly favorable, with offshore breezes from the north and northeast blowing up to 50% of the time in May. This combination of pumping swell and clean offshore winds creates the most pristine surf conditions of the year at Inside Lefts. The waves are often in the 1.5-2.5m range, firing with plenty of punch and shape.

Fair Surf Season (January - April & July - September)

Outside the peak months, the surf remains highly rideable but with compromises. From January through April, the swell is consistently 1.5m with moderate to long periods (12-14s), but the wind is less reliable with onshore westerlies often spoiling the fun. Still, when the north wind sets in, the setup can be excellent. From July to September, the swell reaches its annual peak – averaging 2.0-2.1m with very long periods (14s+) – but the southeast trades dominate, bringing strong side/onshore winds that make conditions challenging. The wave quality is often stormy and lumpy, though the size is impressive. Surfers willing to battle the wind can find heavy, powerful waves.

Low Surf Season (October - December)

As the dry season gives way to the wet season, the swell energy starts to drop off and the wind becomes predominantly unfavorable. October sees the last gasp of big swells (1.8m) but with only 10% ideal wind. November and December see swell heights drop back to 1.5m with shorter periods around 12-13s, and the wind is rarely offshore – often blowing from the west or south. This is the time for small wave boards and patience, though occasional clean windows can still produce fun sessions.

July: Size Rules

July cranks up the size: average swell height jumps to 2.0m with a 14.5s period, offering legitimate pumping waves. Swell directions from S (37.5%) and SSW (44.0%) deliver optimum power. The trade-off is wind: ideal conditions drop to 33%, as southeast trades dominate (SE 46.8%, SSE 14.2%, ESE 15.3%). Offshore flow is scarce (only about 9% from N/NE). The waves are big and sometimes unruly, but when the wind lightens or shifts offshore, you'll be rewarded with heavy, grinding lefts that demand respect.
