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.

October: Light at the End of the Monsoon

October is the turning point. The wind field becomes more variable: offshore directions (SSW–WSW) still blow a combined 64.1%, but northerly winds (N–NE) reappear at 15.6%. Ideal conditions rise to 39%, and the average swell period stays high at 11.0 s. Swell direction finally shows hints of change – east-northeast and east swells begin to register (1.7% combined), though south and south-southwest still dominate (79.3%). The average height drops to 0.9 m, signaling the end of the strong monsoon swell. When a weak north-easterly swell coincides with an offshore wind event, Alwars can produce clean, waist-high waves with a punch. Watch for the first cold fronts pushing through the Bay of Bengal.
