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.

April at Ral Island offers generally modest but surfable conditions with an average swell height of 0.7m and a decent period of 10.1s, indicating well-spaced, clean waves. The swell distribution shows that the majority of waves come from the NNE to NE directions (accounting for over 70% of swells in the 0.5-1.5m range), which typically align well with the break. Swell energy drops significantly beyond 1.5m, with only 0.55% of waves reaching 2m+. Wind conditions are favorable 35% of the time, mostly when light to moderate ENE to E winds (10-20kph) prevail, keeping the surface clean. Stronger winds from the W to WNW (20-30kph) occur occasionally but can disrupt conditions. Overall, expect smaller but ridable waves, best on days with NE swells and light easterly winds—ideal for relaxed surfing rather than high-performance sessions. Wind consistency is the limiting factor, so timing is key.
