Daugo Island - surf spot statistics

Daugo Island in Papua New Guinea experiences a mix of wind swells and ground swells throughout the year, with significant variations in swell consistency and wind conditions. The best time for surfing is generally from April to June, when the swell size is more favorable, averaging around 1.0m to 1.4m. During these months, wind swells dominate, accounting for 87% to 94% of the swell activity, while ground swells remain minimal. Wind conditions also improve slightly in April, with 47% favorable winds—making it the best month overall. May and June still offer decent swell size (1.3m-1.4m), but wind conditions deteriorate slightly, with only 28-40% good wind days. From July to September, the swell remains consistent in height (1.3m-1.4m), but wind conditions worsen, with only 21-27% good wind days, making sessions less reliable. October and November see a slight improvement in wind conditions (38-42% good winds), but swell size decreases (1.1m-0.8m), and the mix of wind and ground swells becomes less predictable. The least favorable period is from December to March, when swell size drops to 0.7m-0.9m, and bad wind conditions dominate (70-87% unfavorable). Ground swells are slightly more present (6-11%) but remain inconsistent. January and February are particularly poor, with only 13-18% good wind days and smaller swells. In summary, April stands out as the peak month for surfing at Daugo Island, offering the best balance of swell size and wind conditions. May and June follow closely with larger swells but slightly less reliable winds. Outside this window, conditions become far less consistent, making early to mid-year the prime time for surfers.

December at Daugo Island offers surfable conditions, though with some variability. The average swell height is modest at 0.7m, paired with a reasonable period of 7.5s, suggesting generally rideable waves, though not particularly powerful. Most swells come from the SE and SSE directions, accounting for the majority of waves between 0.5–1.5m, with occasional bigger sets up to 2m. The wind is favorable for surfing 32% of the time, typically light to moderate (10–20kph) and often from the E to SE directions, which can groom the waves nicely. However, stronger winds (20–30kph) from ESE and SE occasionally disrupt conditions. WSW to WNW winds are less frequent but can create cross-shore or slightly offshore effects, depending on the exact angle. Overall, expect small to medium-sized waves with periods of clean conditions, though wind consistency is a limiting factor. It’s a solid option for surfers comfortable with smaller surf and variable winds.
