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.

November in Wewak offers fairly small but clean conditions for surfers, with an average swell height of 0.5m and a decent period of 10.2s, indicating relatively organized, albeit modest, waves. The majority of swells come from the NNE and NE directions, with 26.38% and 12.65% respectively in the 0-0.5m range, and 24.61% and 14.55% in the 0.5-1m range—making these the most consistent sources of rideable waves. Larger swells (1-1.5m) are rare but occasionally arrive from the NE, E, and NW. Wind conditions are favorable for surfing only 19% of the time, with lighter winds (0-20kph) being most common from the ENE and E, though stronger winds (20-30kph) occasionally blow from the NW, which can create choppier conditions. Overall, expect small, manageable waves with occasional clean sessions when winds cooperate, best suited for longboarding or more relaxed surfing rather than high-performance conditions.
