January: Winter Groundswell and Clean Offshore Windows

January sets the tonal benchmark for Nuevo Vallarta's winter season. Average wave heights hold at a solid 3.3ft (1.0m) and the average period stretches to 13.6s, confirming the North Pacific storm track is feeding long-period energy into the region. The swell rose is overwhelmingly dominated by WNW swell at 73 percent, with an additional 18 percent of pure W and 6 percent NW. This means much of the energy arrives slightly angled to the west-southwest-facing beach, so the best shapes result when the more westerly pulses align with the bay. Over 48 percent of readings fall in the 3-5ft (1-1.5m) range, offering genuinely fun, rippable waves.

Wind quality is a major plus, with ideal offshore conditions 66 percent of the time. Light ENE and E winds are the go-to, especially in the early morning before the land breeze fades; NW and NNW afternoon flow dominates the rest of the day but is generally light. Air temperatures average 19.4°C and rain is limited to under 1mm per day, while water temperature sits at a warm 25.5°C. If you time the dawn offshore window, January delivers clean, long-period surf.
