The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Picao.
Right off the bat, I gotta be straight with you – it’s a tough stretch ahead. The forecast is serving up a long, frustrating run of poor surf conditions. For the first week or more, the wind is a constant problem. We’re looking at cross-offshore breezes at 12 to 19 mph nearly every day, and that’s just ruining any chance of clean, well-shaped waves. The water temp is sitting at a balmy 81° right now, which is just about 1° warmer than average for this time of year – nothing crazy, just a little on the warm side.
There’s a bit of a bump in energy on Thursday the 13th of August, with the combined swell energy hitting 370 (moderate), and a 5 ft swell from the southeast, but the wind is still cross-off and the report calls it “marginal.” That’s not the sort of thing you mark on your calendar.
We don’t see any true green lights. The whole run is plagued by poor conditions. For a spot like Picao, a consistent reef break that works best with a NE swell, we’re stuck with east and southeast swells all the way through. The period on most of these swells is short, mostly 6 to 8 seconds, which means weaker, less organized waves.
If you’re desperate for a paddle, Saturday the 22nd of August might be your best bet – still not good, but the wind drops to a gentle breeze at 9 mph from the ESE, keeping things cross-shore. The swell is tiny at 3 ft with weak energy (114), so it’s a long shot.
Honestly, this is a blank run. There are no standout days for quality surfing in this 16-day window. Picao isn’t known for firing under these conditions, so this run of poor surf is pretty normal when the wind and swell don’t align.
Rusty.
