Conditions at Vairao in August
August: Continued South Swell Slant
August is the tail of the deep winter season, and the character of the surf is almost identical to July. Average heights remain at 7ft (2.2m) and period at 12.2s. The S swell still headlines with 22.4%, while SSE is close behind at 21.0%; SSW, SE and a touch of ESE round out the rest. Only about 3.2% of the total wave energy arrives from the ideal SW-WNW quadrant. The long-period aspect remains potent, but again, direction is the limiting factor for Vairao.
The wind is still very trade-dominated-E and ESE combine for a big share, but ideal conditions are low at 25%, with strong 20-40kph winds frequently blowing. There is very little onshore flow, so any surf that does make the reef during light ENE or E periods will be clean and offshore. Water temperature sits at 26.2°C, air at 24.8°C, and precipitation stays minimal at 1.72mm/day. Look for the rare SW pulse in August for an unexpected score, but don't hold your breath.
