Shivas seasonal overview

Best Surf Season (November - February)

The winter months deliver the most consistent combination of favourable winds and rideable swell for Shivas. As the Indian winter monsoon sets in, a stable high-pressure system over the subcontinent funnels cool, offshore winds from the NNE and ENE across the coast, creating clean conditions over 60% of the time. While the dominant swell direction shifts toward the W and WNW – not optimal but still capable of wrapping into the bay – the average wave height hovers around 0.8-0.9m with a punchy period of 9-10s. These are the months to point your board south-west and enjoy glassy, fun-sized waves before the afternoon sea breeze kicks in.

Fair Surf Season (March - April & September - October)

Transitional periods bring a trade-off. In March and April, the offshore wind window narrows to about 30-42%, but the swell direction swings more favourably toward the SW and WSW, producing consistent 1m waves with a longer, more powerful 10-11s period. Similarly, September and October see the tail end of the summer swell and the onset of the northeast monsoon, with ideal wind percentages climbing back to 40% while the swell remains solid and well-directed from the SSW and SW. These months can dish out excellent sessions when the synoptic setup aligns, but you’ll need to pick your windows carefully.

Low Surf Season (May - August)

Shivas essentially goes dormant during the peak of the Indian summer. From May through August, the dominant southwest monsoon winds blow directly onshore from the W and WSW, ruining wave quality and making the ocean a bumpy, choppy mess. Average wave height actually peaks at a heavy 2.3-2.5m in June and July, but it comes with onshore winds over 90% of the time and a short, windswell-like period around 10s. Unless you enjoy closeouts and whitewash, it’s best to leave the board at home and wait for the monsoon to retreat.

Conditions at Shivas in December

December: Peak Season Locked In

December closes out the year on a high note. With ideal offshore winds 61% of the time and an average swell height of 0.8m at a solid 10.0s period, it’s a reliable month for clean, fun-sized waves. Swell directions are split between S, SSW, and SW (the optimal zone) and some W/NW energy, but the best lines come from the SSW. The long, consistent period ensures that even the smaller days offer a worthwhile wave. Morning sessions are key, as the offshore ENE winds groom the faces into long, peeling walls. December is a staple for Shivas and a month every surfer should mark on the calendar.
