Hyatt Reef - surf spot statistics

Hyatt Reef in Indonesia offers consistent year-round ground swell conditions, with minimal or no wind swell interference, making it a reliable surf destination. The best months for surfing here are from January to March and November to December, when swell consistency remains high (92–98% ground swell) and wind conditions are more favorable compared to the mid-year period. January and February stand out with good wind conditions over 50% of the time, combined with a mean swell size of around 1.6 meters, providing ideal, clean waves. March and December also offer decent wind conditions but with slightly higher variability (45–56% favorable winds). The mid-year period (May–September) sees larger swells (1.8–2.2 meters), but offshore wind conditions deteriorate significantly, with unfavorable winds exceeding 94% of the time, making it much less appealing for surfers seeking clean faces. April and October serve as transitional months, with April having poor winds (only 19% favorable) and October marginally better but still unreliable (6% good winds). Overall, Hyatt Reef delivers the best balance of swell quality and wind conditions in the early and late parts of the year, while the peak swell season (June–August) is more suited to experienced surfers willing to battle the persistent onshore winds.

August at Hyatt Reef delivers consistent, high-quality surf with an average swell height of 2.2m and a long 15s period, indicating powerful, well-spaced waves. The dominant swell direction is from the SSW and SW, contributing over 60% of waves in the 1.5–2.5m range—ideal for advanced surfers seeking size and energy. While smaller SE/SSE swells occasionally mix in, they rarely exceed 1.5m. Wind conditions, however, are less favorable: ESE and SE winds dominate at 10–30kph (75% of the time), creating onshore chop that disrupts wave faces. Only 0% of wind conditions are ideal, meaning surfers will frequently contend with cross-onshore breezes. Despite this, the spot’s exposure to southern swells ensures consistent rideable waves, though optimal sessions will rely on rare lulls in the wind. Expect powerful, slightly messy conditions with strong offshore currents.
