Conditions at Vairao in January
January: Midsummer Energy, Offshore Trade-Wind Glitter
January sits right in the middle of the South Pacific wet season, and Vairao sees a peak of activity from two very different angles. The average surf height runs 5-6ft (1.7m) with a solid 11.7s period, but a closer look at the wave rose shows that the bulk of the energy arrives out of the SSE and S, with a firm secondary push from the SSW and SE. That southern quadrant is not the money direction for this west-facing reef; Vairao really needs the swell to lean into the SW, WSW, W or WNW to push clean lines through the bay.
Still, January has more workable westerly energy than most months-roughly 13% of the total swell comes from the SW-WNW window. Combine those pulses with the NE-ESE trade winds that blow offshore roughly 35% of the time, and you get periods of clean, lined-up, pumping waves. The water is a warm 28.4°C, air temps hover around 27°C, and with 6.46mm/day of precipitation, you can expect tropical showers to come and go. It's sticky, dynamic, and full of potential.
