The Lowdown
Alright folks, Rusty here. Let's talk about what's coming up for Playa de Seaia over the next couple of weeks.
The first few days are a bit of a mixed bag. We’ve got some surfable waves, but conditions are ordinary. The real action starts to build towards the end of the month and into early September. Hold on for a standout window around Monday the 31st of August.
The water temperature is about average for this time of year, so nothing crazy to worry about there.
The standout session is hands down Monday morning, the 31st of August. The swell is a solid 7ft out of the NW, with a period of 10 seconds, pumping in a moderate amount of energy (769). The wind is glassy, dead calm, which means the surface will be like a mirror. This is a great time to be out there, no crowds to worry about at this point, and the conditions are set to be very good. The swell direction from the NW is a good match for what this spot likes.
Saturday morning, the 29th of August, has a smaller 6ft W swell with a short 8-second period, but the wind is cross-offshore and it's a bit bumpy. The better option that day is the afternoon, with a 6ft WNW swell, clean offshore winds, and moderate energy (449). It’s not the best of the week, but it’s a solid option.
Sunday the 30th has a good morning window. 6ft NW swell, 10-second period, light offshore winds, and a decent amount of energy (612). It’s a clean, fun morning.
Sunday afternoon fades a bit with cross-offshore winds and a drop in quality.
Monday the 31st afternoon is still surfable with a 6ft NW swell, but the wind goes cross-shore, so it’s not as clean as the morning glass-off.
From Tuesday the 1st of September onward, the outlook gets pretty grim. Onshore winds and poor conditions dominate for a solid week. There’s a small window of hope on Sunday the 6th of September, with a 5ft NW swell, 11-second period, and glassy conditions in the morning and clean offshore in the afternoon. It’s a good surf window, but nothing massive.
The rest of the second week is mostly poor with onshore winds and choppy conditions, especially as the swell builds to over 7ft by mid-week. The setup will be more interesting for kite surfing than paddle surfing during those days of strong onshore winds and bigger, messy swell.
So, in short: get your best sessions in on Monday the 31st of August morning, and maybe Sunday the 6th of September. The rest is a wait-and-see game.
Rusty out.

Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Playa de Seaia may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
