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.

January: The Onshore Grip

January is the heart of the northeast monsoon, with the wind blowing from NNE–NE a crushing 74% of the time – directly onshore for Alwars’ east-northeast facing beach. Swell direction is actually favorable, with 48.8% of waves arriving from the east-northeast and another 19% from the east, but the average period is a short 7.5 s, producing weak, short-period lines. With ideal wind conditions occurring a mere 1% of the time, most days are a choppy, rippled mess. Any rideable waves are rare and require a sudden southerly wind shift, which is statistically unlikely. If you’re desperate, a log or a foil might salvage a micro session, but expectations should be set to minimal.
