Wewak - surf spot statistics

Wewak, Papua New Guinea, offers surfable conditions year-round, but the best months for quality waves and favorable winds are December through February, with a secondary window in November and March. During these months, ground swell frequency peaks (30-41%), and wind swell remains consistent (41-55%), ensuring rideable waves. The mean swell size hovers around 0.7m—small but sufficient for beginners and intermediates. Wind conditions are relatively better in these months, with 33-34% good wind days, though onshore winds still dominate (66-67%). From April to October, surf potential drops significantly due to a steep decline in ground swell (1-22%) and persistently poor wind conditions (79-93%). Swell size also diminishes to 0.5-0.6m, making sessions unreliable. May through September are particularly weak, with ground swell nearly absent (1-10%) and strong unfavorable winds (90-93%). October marks a transition as ground swell begins to rebuild (22%) but remains hampered by poor winds (90%). For the most consistent surf, target the wet season (December-February) when swell energy, frequency, and marginal wind improvements align best. However, even in peak months, expect frequent onshore winds and smaller waves—ideal for relaxed surfing rather than high-performance conditions.

In April, Wewak offers generally small but rideable surf with an average swell height of 0.5m and a decent period of 9.6s. Most waves come from NNE and NE directions, with the majority being under 1m (around 20% each). Occasionally, slightly larger waves (1-1.5m) appear from NNW and NW, but anything over 1.5m is rare. Wind conditions are variable, with only 21% of the time being ideal for surfing. The most favorable winds are light (under 20kph) and primarily from the E to SE quadrant. However, stronger NW and WNW winds (20-30kph+) occur frequently, potentially creating choppy or onshore conditions. Overall, April is a mixed month—best suited for mellow sessions when the swell aligns with lighter offshore winds, but consistency and size are limited. Experienced surfers may find short clean windows, but don’t expect powerful or barreling conditions.
