January: Long-Period Northwest Swell Meets Winter Wind
January is the heart of the North Pacific swell season for Sayulita. The average swell height checks in at 1.0m (3.3ft) and the average period is a powerful 13.6s. The wave rose is dominated by WNW energy at 55.9%, with W at 32.2% and NW at 4.7%; nearly a third of the WNW contribution sits in the 1-1.5m (3.3-4.9ft) class, and there are occasional 1.5-2.5m (4.9-8.2ft) sets. This is exactly the kind of long-period groundswell that can make the NNW-facing bay work. However, wind is the great equalizer. NNW winds blow 38.6% of the time, N winds 17.0% and NW winds 9.5%, meaning around 65% of January observations feature onshore or cross-onshore flow. With ideal offshore winds only 4% of the time, those WNW lines are often chopped up. Keep an eye on cold-front passages that swing the wind into the S/SSW/SW/WSW quadrant; the rare calm windows deliver 3-5ft (0.9-1.5m) glassy groundswell with water temperature 25.0 degrees C and air mostly in the low 20s C.
