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 September, Wewak offers marginal surf conditions with an average swell height of 0.6m and a period of 7.9s, indicating weak and inconsistent waves. The dominant swell direction is from the east (E), contributing 29.48% of waves in the 0.5-1m range and 4.17% in the 1-1.5m range, while other directions rarely produce rideable waves. Wind conditions are often less than ideal, with only 8% of the time offering favorable winds for surfing. The ENE and E winds are the strongest, frequently blowing at 10-30kph (9.70% at 10-20kph ENE, 15.27% at 10-20kph E), which can create choppy or onshore conditions. Surfers should expect mostly small, gutless waves, with occasional waist-high sets when easterly swells align. Windswell from the E/ENE may provide short, weak peaks, but overall, September is not a prime time for quality surf here—best suited for beginners or those looking for very mellow sessions. Advanced surfers will find it underwhelming unless an unusual swell event occurs.
