The Lowdown
Alright, folks, Rusty here. Let's have a look at what's on the table.
Right off the bat, we're looking at a bit of a slow start. The first few days at Atalaia (Molhes) are pretty grim, so don't get your hopes up. We've got a long stretch of small, weak swell with poor conditions through Monday and Tuesday. Honestly, you'd be better off waxing your board and waiting.
It's not until late in the week, around Thursday morning the 13th, that things start to look interesting. That's where the forecast perks up. We've got a solid 3ft swell from the SE with a period of a long 15 seconds, giving it that groundswell feel and a combined moderate wave energy of (338). The water temp is running about average for this time of year, nothing unusual. The real kicker is the clean, offshore wind from the WNW, which is exactly what this jetty setup needs to make the most of that SE direction. This is a standout for the whole window, so if you can sneak a session Thursday morning, that's your best bet for a proper wave.
Friday the 14th afternoon is also worth a mention. The swell drops a hair to 3ft from the SE with a 14-second period and combined energy of (309). The winds turn glassy with a slight ENE breeze, and the conditions clean up. It's not the standout Thursday is, but it’s surfable and very ordinary in a good way. Perfect for a long, slow evening session if the tide is friendly.
Saturday the 15th and Sunday the 16th are limp, small, and sloppy. Not worth the paddle. Things stay pretty quiet until we get a blink at the end of the period.
Looking way down the line, Sunday morning the 23rd of August is a notable one to keep in the back of your mind. It's a long way out, so take it with a grain of salt, but it’s showing a 4ft SE swell with a 12-second period, combined energy of (366), and glassy conditions. If that holds, it could be the other real standout of the whole 16 days. We’ll see.
So in summary, don't waste your time this week until Thursday morning the 13th. That's the one to circle for a clean, offshore window with proper groundswell. Sunday the 23rd is the distant wildcard.
Rusty out.
