Alwars - surf spot statistics

Best Surf Season (March & November)

The transitional months of March and November offer the most balanced trade-offs at Alwars. During these windows, the northeast monsoon wanes and the southwest monsoon establishes (or vice versa), creating episodic synergy between optimal ENE–E swell and light-to-moderate SSW–SW offshore winds. While consistency is fleeting and swell heights average only 0.8–0.9 m, periods climb into the 10–11 s range, bringing rideable, punchy waves when the alignment locks in. These are your best bets for clean-ish corners along this east-northeast facing beach.

Fair Surf Season (February, December)

February and December deliver the highest frequency of optimal swell directions (ENE, E, NE), but the northeast monsoon grips the coast with relentless NNE–NE onshore winds, blowing a staggering 70–80% of the time. The average wave period here sits at a choppy 8–9 s, and only a few southerly wind shifts (SSW–SW) during cold-front passages or pressure troughs offer rare, clean sessions. Expect mostly messy, crumbly waves unless you can hunt a rogue offshore window.

Low Surf Season (April – October)

The southwest monsoon dominates from April through October, filling the Indian Ocean with long-period (10–11 s) swell generated by persistent tropical lows and mid-latitude depressions. However, the swell arrives from the south and south-southwest – a direction that misses the optimal exposure of Alwars completely. Even though offshore winds from the SSW–WSW quadrant blow 20–50% of the time (peaking in April), the wave energy is either blocked by the coastline or heavily refracted into micro, close-outs. The result is a long stretch of flat-to-small conditions, best left for a beach walk or a change of venue.

May: Monsoon Surge, Wrong Angle

The southwest monsoon strengthens in May, driving strong winds from the WSW and SW (84.4% combined) at 20–40 kph, ideal for offshore trimming but often blowing hard. Swell direction locks into a southerly groove: 52.8% from the south-southwest and 40.9% from the south, with an average height of 1.0 m and a 10.3 s period. These are proper south swells, but they approach the coast at an oblique angle, leaving Alwars in a shadow. The beach sees mostly short, steep close-outs and lots of whitewash. The wind may be glassy offshore, but the wave quality is poor. Best alternative: hit a south-facing reef nearby.
