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.

June: South Swell Saturation

June is all about the south-southwest swell machine, with 66.3% of waves arriving from the SSW and 30.6% from due south. The average height hits 1.1 m and period 10.6 s, indicating solid, long-period energy, but it’s almost entirely wasted at Alwars. The wind blows from the southwest quadrant 96.3% of the time, with WSW dominating at 73.9% and strong speeds of 20–40+ kph. These are offshore winds, yes, but they whip the surface into vertical chop while the swell fails to wrap in. Ideal conditions drop to just 9% – a reflection of the constant sideshore wind and misfit swell. Check the charts for a rare southerly wind shift, but don’t hold your breath.
