Conditions at Nuevo Vallarta in August
August: Warm Waters and Tropical Unrest
August follows a very similar summer template. Swell remains small, averaging 0.9m (3ft), but the direction is ideal, with SW at 61.2 percent, SSW at 25.5 percent, and WSW at 12 percent. The 0.5-1m (2-3ft) class accounts for about 76 percent of all swell readings, and the average period drops slightly to 13.4s. The bay becomes a grovel-or-longboard zone, with occasional bigger pulses if an eastern Pacific tropical storm moves into range.
Offshore winds are actually present 58 percent of the time, so early mornings often look clean despite the small surf. Air temperatures stay warm at 23.6°C, rainfall is heavy at 9.70mm/day, and water temperature reaches its annual peak near 30.8°C. Patience is the name of the game; the summer swells are consistent in direction but not in size.
