Log Cabins - surf spot statistics

Log Cabins, located on the North Shore of Oahu, is a powerful and consistent surf spot with a strong seasonal pattern. The best months for surfing are typically from November through March, when ground swells dominate, averaging 2.0–2.4 meters in height. During these winter months, ground swell occurrence is high (75–91%), providing clean, powerful waves ideal for experienced surfers. However, wind conditions are less favorable, with only 27–33% of days having good winds, meaning strong onshore or cross-shore winds are common. The peak swell months are January and December, with the largest waves (2.4m and 2.2m respectively), though wind interference remains a challenge. From April through October, swell size decreases significantly (1.2–1.7m), and wind swells become more prevalent, peaking in June–August (78–87% wind swell). These summer months offer smaller, less consistent waves, with only 22–28% of days having clean wind conditions. September and October show a transition phase, with improving ground swell presence (36–62%) and slightly better winds (36% good conditions), making early fall a decent option before the winter swells fully build. Overall, the prime window for high-quality surfing at Log Cabins is winter (November–March), particularly December–February, when large, clean ground swells are most frequent. However, surfers must contend with often unfavorable winds. Summertime provides smaller, choppier waves, better suited for intermediate surfers or those less reliant on perfect conditions.

April at Log Cabins offers decent surf conditions with an average swell height of 1.7m and a favorable period of 11.2s, indicating consistent, well-spaced waves. The dominant swell directions are NW and NNW, delivering the best wave energy with 11.9% and 9.87% of waves in the 1-1.5m range, respectively, and 12.74% (NW) and 10.6% (NNW) in the 1.5-2m range. Larger waves (2m+) are possible, particularly from these directions, though less frequent. Wind conditions are somewhat variable, with ENE winds being the strongest and most consistent (15.19% at 20-30kph and 14.98% at 30-40kph), which can create chop or cross-shore effects. However, there’s a 23% chance of ideal offshore winds—typically light winds from the land, which help groom the swell. Surfers can expect the best sessions when NW/NNW swells coincide with lighter winds, offering clean, powerful waves. While not a big-wave month, April provides reliable, mid-sized surf with occasional standout days for experienced riders. Wind management is key, as ENE gusts can disrupt conditions.
