Nago - surf spot statistics

Nago, Papua New Guinea, offers surfable conditions year-round, but the best months for surfers are from October to March when ground swell dominates and wave consistency is higher. During this period, the mean swell size ranges from 0.7m to 1.0m, with ground swell percentage peaking at 55-56% in December and January. Wind conditions are less favorable, with good wind days averaging only 26-39% from November to March, but the swell quality compensates for the often onshore or cross-shore winds. The worst months are from May to September, when no-swell days increase significantly (34-48%), ground swell drops below 20%, and mean swell size decreases to 0.5-0.6m. Wind conditions deteriorate further in these months, with bad wind probabilities exceeding 77%. April and November are transition months, offering a mix of ground and wind swells, but November stands out as a better option due to higher ground swell influence (48%) and slightly improved wind conditions (39% good winds). For consistent, quality waves with manageable wind interference, target December through February, accepting that wind conditions may not be perfect but swell reliability is strongest. The summer months also bring larger waves compared to the rest of the year, making them the prime surf season despite the higher likelihood of unfavorable winds.

July at Nago, Papua New Guinea, offers generally small to moderate surf conditions with an average swell height of 0.5m and a decent average period of 7.2s, providing some energy despite the modest size. The swell is predominantly from the northeast (NE, ENE), making up the majority of wave activity, with occasional contributions from the east (E, ESE). These directions tend to align best with the beach setup, offering the most rideable waves, though they mostly fall in the 0.5-1.5m range, rarely exceeding 1.5m, which means surfers can expect playful, manageable conditions rather than powerful waves. Wind is the limiting factor here—only 18% of the time is it ideal for surfing, as the dominant ESE and SE winds often blow at 10-30kph, creating choppy or cross-shore conditions. Lighter winds from the northeast or ENE provide the cleanest sessions, but they’re less frequent. Overall, July is a month for intermediate surfers looking for smaller, fun waves, with patience needed for those occasional clean, wind-protected days when the NE swell and lighter winds align. It’s not a high-performance month, but there are enough opportunities for relaxed surfing if you time it right.
