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.

Hyatt Reef in December offers consistent surf with an average swell height of 1.5m and a solid period of 13.2s, indicating powerful, well-spaced waves. The swell is predominantly from the SSW and SW directions, with the majority of waves falling in the 1-2m range (25-47% of occurrences), providing ideal conditions for intermediate to advanced surfers. Larger sets occasionally reach 2.5m+, but they’re rare (6.24% SSW, 1.74% SW). Wind conditions are favorable 44% of the time, with the biggest concerns being W to WSW winds, which can bring onshore gusts of 20-30kph (9.89% WSW, 8.06% W). Light offshore or cross-offshore winds (E to SE) occur less frequently but create cleaner conditions when present. Overall, December delivers reliable, punchy waves with good shape, though wind variability means timing sessions around lighter W/SW winds or early mornings will yield the best results. Advanced surfers will find the most potential here, especially when SW swells align with lighter winds.
