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.

February in Wewak offers generally small but clean conditions, with an average swell height of 0.7m and a decent period of 10.1s, providing some energy despite the modest size. The most consistent swell direction is from the NNE (38.86% of waves in the 0.5-1m range), followed by NNW and NE, ensuring manageable but not overly powerful waves. Larger swells (1.5m+) are rare, mostly arriving from the NW or NNW but account for less than 1% of conditions—expect mostly knee- to waist-high waves with occasional chest-high sets. Wind is a limiting factor, with only 33% of days offering ideal offshore or light cross-shore winds; the dominant WNW and NW winds (10-30kph) can create chop, especially in the afternoons. For surfers, the spot works best on days with NNE swell and lighter winds, favoring a longboard or fish for the smaller days, though bigger NW swells (though infrequent) could briefly suit a shortboard. Overall, February is consistent but not epic—best for relaxed sessions or beginners, with occasional windows for more experienced surfers.
