The Lowdown
G’day, Rusty here. Let’s cut to it – Picao (Baia Formosa) is pretty quiet for the next stretch. The reef is exposed but the swell isn’t coming from its favourite northeast direction. We’re looking at a long gap of about 13 days before the surf shows any sign of life.
Water temp is 27°, about 0.8° warmer than average for this time of year – nothing extreme.
Sunday 16 August to Wednesday 27 August – cross-offshore winds with moderate to fresh breezes, but swell’s small: from 1.0ft to 5ft, with short periods of 6 to 7 seconds. Combined swell energy is weak to moderate (27 to 239). The waves are clean but gutless – not worth the drive.
Now, Saturday 29 August – things perk up. In the morning, we’ve got clean 5ft east swell at 8 seconds, combined swell energy at 247, with a moderate cross-offshore breeze. By the afternoon, it builds to 5ft from the east, same period, and the energy jumps to 309. That afternoon window is the best shot – still marginal, but it’s the most surfable we’ve seen in weeks. This is for intermediates; beginners might find the 5ft a bit too much.
Then Sunday 30 August and Monday 31 August keep the swell rolling: 5ft to 5ft east, 8-second period, and combined energy in the 302 to 322 range. It’s cross-shore wind, so some chop, but if you pick your spot, you’ll find a few.
Crowds are possible, but not too bad with this low-key run.
The standout: Saturday 29 August afternoon. Clean, 5ft east swell, moderate energy – that’s your wave.
