Alwars seasonal overview

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.

Conditions at Alwars in September

September: Monsoon Taper, Still Mismatched

September sees the southwest monsoon begin to weaken, but the swell remains stubbornly southerly: 60.2% from the south and 37% from the south-southwest. Average height holds at 1.0 m with a 10.8 s period – still long and powerful. Wind shifts slowly; WSW still dominates at 53.3%, but SW contributions increase to 33.8%, and lighter winds appear. Ideal wind sits at 24%, offering clean offshore conditions at times. But the swell direction barely improves – east-southeast energies are nil. A few small east-northeast pulses (0.0%) don’t materialize. The occasional tropical disturbance can swing winds southerly, but typically Alwars remains quiet. Patience is key.
