Hyatt Reef - surf spot statistics

Best Surf Season (December - March)

During these months, Hyatt Reef comes alive as the winter monsoon shifts to deliver consistent offshore winds from the west and northwest. The Indian Ocean's Southern Swell machine is still churning, but the big story is the wind. With the Siberian high-pressure system influencing the region, we see a dominance of dry, offshore flow that grooms the long-period SW groundswell into clean, peeling lines. Average wave heights hover around 1.6-1.7m but the quality is top-tier – think fun, rippable waves with occasional pumping 1.5-2.5m sets when a stronger storm track aligns. The period averages 12-13s, providing plenty of punch.

Fair Surf Season (April & November)

These shoulder months see the winds transitioning. April still picks up solid SSW swell – the dominant direction – but the trades begin to build from the southeast, reducing ideal wind frequencies to around 19%. November is the reverse: the trades are fading, and westerly winds are slowly returning, with 29% ideal conditions. The swell remains consistent and powerful, so if you can catch a window with lighter winds, the rewards are there. It's a game of patience and reading the synoptic charts.

Low Surf Season (May - October)

The southeast trades become relentless from May through October, slamming the beach with onshore winds that turn the otherwise perfect SSW swell into choppy, messy surf. Despite larger average heights (2.0-2.2m) and longer periods (14s+), the quality is severely compromised. The winds blow predominantly from the ESE and SE at speeds often exceeding 20kph, creating bumpy conditions. Occasional westerly wind shifts can occur during tropical systems or frontal passages, but these are rare. For surfers who can handle onshore waves, there are still powerful waves to be had, especially at lower tide, but this is by far the most challenging time of year at Hyatt Reef.

September: Swell Holding, Winds Relenting

September begins to show a slight easing of the trades, but it's still deep in the low season. Average swell is 2.0m with a 14.3s period – still very solid. SSW accounts for a massive 70.9% of the swell, so direction is dead-on. However, ideal wind is just 2%. The SE (37.5%) and ESE (36.6%) winds still dominate, but at lighter speeds compared to mid-summer. There's a slight increase in W, NW winds (negligible) and more variable directions. It's still mostly onshore, but occasional windows of cleaner conditions may appear as the monsoon pattern shifts. Good for those who can wait for the rare offshore window.
