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.

July at Ral Island offers small to very small surf, with an average swell height of just 0.5m and a modest 7.2s period. Most waves (over 80%) are under 1m, with the dominant swell directions coming from NE (21.7% at 0-0.5m, 9.11% at 0.5-1m) and ENE (9.38% at 0-0.5m, 6.41% at 0.5-1m). Very few swells exceed 1.5m, mostly from E and ESE, but these are rare (under 1% combined). Wind conditions are challenging for surfers—only 19% of the time are winds ideal (likely light offshore or cross-offshore). The prevailing winds are from ESE (12.12% at 10-20kph, 11.52% at 20-30kph) and SE (10.37% at 10-20kph), often blowing onshore or strong cross-shore, which can create chop. Surfers will need patience for the occasional clean, rideable wave, but expect mostly weak, wind-affected conditions. Advanced riders may find rare, slightly bigger days from E/ESE swells, but overall, July is inconsistent and better suited to relaxed surfing or beginners.
