Ral Island - surf spot statistics

Ral Island in Papua New Guinea offers surfable conditions year-round, though the best months for quality waves are from November to March. During this period, ground swell dominates (48-56% of the time), providing more consistent and powerful waves with mean swell sizes ranging from 0.7 to 1.0 meters. December and January are particularly good, with ground swell peaking at 55-56% and decent swell sizes. Wind conditions, however, are less favorable, with bad winds occurring 64-83% of the time, making offshore winds rarer but still possible. April and October are transitional months with a mix of ground and wind swell, but wind conditions improve slightly (29-35% good winds). Swell size drops to 0.6-0.7 meters, making them decent but not ideal for advanced surfers. From May to September, conditions deteriorate significantly, with low ground swell (2-20%), frequent flat spells (34-48% no swell), and small waves (0.5-0.6 meters). Wind conditions remain mostly poor, further reducing surf quality. For the best experience, target late November through early March when ground swell is strongest, despite challenging winds. If you prioritize cleaner conditions over wave power, April and October offer a compromise with slightly better winds and manageable swell. Avoid mid-year (May-September) when weak swells and onshore winds prevail.

In June, Ral Island experiences generally small surf conditions with an average swell height of 0.5m and a moderate period of 8.0s, indicating somewhat weak but relatively clean waves. The swell is predominantly from the NE (27.4% of waves in the 0-0.5m range, 22.88% in the 0.5-1m range), with occasional contributions from E and ESE directions at slightly larger heights (up to 1.5m). However, waves above 1.5m are extremely rare, making this month more suited for beginners or longboarders rather than high-performance surfing. The wind is favorable for surfing only 21% of the time, with the strongest and most consistent winds coming from the ESE and E directions (10-30kph range), which can create choppy or cross-shore conditions. Cleaner sessions are likely when lighter winds align offshores from the NW or W, but these are infrequent. Overall, June offers small, manageable waves with occasional clean windows, best suited for relaxed surfing rather than high-energy sessions.
