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.

December at Nago, Papua New Guinea offers generally manageable surf conditions with an average swell height of 0.9m and a solid period of 10.9s, indicating consistent, well-formed waves. The swell is predominantly from the NNE direction, contributing 36.87% of waves in the 0.5-1m range and 8.99% in the 1-1.5m range, providing a mix of smaller, rideable waves and occasional punchier sets. Larger waves (1.5-2.5m) are less frequent but present, mainly from W, WNW, and NNW directions, offering variety for more experienced surfers. Wind conditions are a limiting factor, with only 30% of days providing ideal offshore or light cross-shore winds—typically from the NE to ENE sectors. Stronger onshore winds (WSW to NW) occur frequently, creating choppy conditions, particularly in the afternoons. Overall, December delivers surfable waves, especially in the mornings when winds are lighter, but expect variable wind interference and focus on swells from the NNE for the cleanest conditions.
