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 May, Wewak’s surf conditions are generally small and inconsistent, with an average swell height of just 0.5m and a modest period of 8.6s, suggesting weak energy in the waves. The majority of swells come from the NE and NNE directions (over 60% combined), primarily in the 0-1.5m range, making for very small, mellow conditions—ideal for beginners or longboarders rather than advanced surfers seeking power. Only a tiny fraction of swells reach 1.5-2m, and anything overhead is virtually nonexistent. Wind conditions are less than ideal, with just 9% of days offering favorable offshore or light winds for surfing. The dominant ENE to ESE winds (often 10-30kph) are likely cross-shore or onshore, creating choppy or semi-choppy conditions. Overall, May is a quiet month here, best suited for relaxed surfing when winds align, but don’t expect significant swell energy or clean conditions often. Advanced surfers may find it underwhelming unless chasing rare, slightly bigger NE pulses.
