Conditions at Waikiki Beach in January
January: Peak North Pacific Power
January is the heart of the North Pacific surf season for this stretch. The average swell height reaches 6ft (1.8m) with a long-period average of 12.6 seconds, the highest of the year. The waverose tells the story: NW swell leads at 21.6%, followed by WNW at 13.6% and NNW at 11.9%, with an additional 18.4% coming from NNE/NE/ENE. In other words, the optimal N/NNW/NW corridor is firing. A good share of the swell sits in the 5-8ft (1.5-2.5m) range, and waves over 8ft (2.5m) are rare but possible.
Winds, however, are the limiting factor. The ENE trades blow 29.9% of the time, and NE/E add another 24%, producing a bumpy, cross-textured ocean. The clean offshore S/SSW/SW window appears 23% of the time, mostly as light-to-moderate flow, and that is when the long-period NW groundswell lines up as clean, powerful waves. Average air temperatures of 22.8°C and water temperatures of 24.5°C make for pleasant tropical winter sessions, though 1.99mm/day of rain means occasional passing showers.
