Conditions at Arrifana in August
August: Slightly Better Summer Pulse
August remains summery but shows a hint of improvement. The average swell is still 1.4m (4-5ft), yet the period ticks up to 8.7s and the ideal wind percentage rises to 41%. NW swell leads the pack at 47.2%, with NNW close behind at 41.4% and WNW adding 6.9%. The dramatic decrease in direct W swell means Arrifana still lacks true quality, but lighter winds and longer-period NW pulses can make the early mornings fun. The wind rose is still NNW-heavy (54.4%), though not quite as aggressive as July. Water is warmest of the year at 17.9C, air reaches 23.1C, and almost no rain falls. Keep a shortboard and a wide-open schedule.
