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.

November: The Sweet Spot Emerges

November is Alwars’ most promising month. The northeast monsoon re-establishes, bringing a mix of swell directions: east-northeast (15.1%), east (12.1%), and northeast (6.6%) now total 33.8% – the highest optimal swell percentage since March. South swell still contributes 40.6%, but the window for east energy is growing. Wind is still predominantly NNE (30%) and NE (18.4%), but offshore contributions from SW–WSW hit 15.2%, and ideal conditions reach 21%. The average period is 10.3 s, with a modest 0.8 m height. When a north-easterly pulse arrives ahead of a cold front, and the wind switches to the SW quadrant, Alwars lights up with clean, chest-high lines. It’s a gamble, but the odds are better than any other month.
