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.

November: Winds Shift, Surf Delivers

November marks a real improvement in surf quality. The average swell is 1.6m with a 13.2s period – slightly smaller but still plenty of punch from the SSW (83.5%). The key change is the wind: ideal wind frequency jumps to 29%. The trades are much weaker, with ESE and SE winds dropping to around 17% and 16% respectively, and wind speeds mostly under 20kph. The westerly winds (WSW 9.2%, W 8.7%) become more prominent, offering clean, offshore conditions more often. When the synoptic setup is right, you'll find glassy, long-period swell wrapping into the reef. This month bridges the gap into the peak season.
