The Lowdown
Alright folks, Rusty here. Let's get straight into what's on the table for the next couple of weeks.
It's a pretty grim stretch on the whole, I gotta be honest. We're looking at a long run of days where the surf just isn't cooperating. The only flicker of something to talk about pops up on Monday the 24th (August), but even that is a marginal call. For the rest of the 16-day window, it's mostly poor surf conditions with cross-offshore or cross-onshore winds, and the swell is weak and short-period.
The one spot we've got to work with is Picao (Baia Formosa). It's a consistent reef break, fairly exposed, but the swell direction it needs is northeast, and what we're getting is a lot of ESE and E. On Monday morning the 24th, the combined energy bumps up to a moderate 400, with a swell height of 5 ft from the east, a short period of 7 seconds. The wind is a gentle cross-offshore breeze from the ESE, which will keep the surface clean. The water temperature is sitting at 81°, which is about normal for this time of year. However, the forecast is rated as marginal, so it's a gamble. The rest of the week is a write-off with fresh breezes and poor conditions.
The following week, from the 28th of August through to the 3rd of September, is even worse. The swell drops off, the energy is weak (down to around 129-174), and the winds turn more onshore and cross-onshore, making for choppy, messy conditions. There's just nothing to recommend here.
If you're desperate, Monday morning the 24th at Picao is your only real chance, but keep your expectations low. For the rest, it's a waiting game.
Rusty.
