The Lowdown
Alright folks, Rusty here. Let’s get into it.
First up, let’s be real: this outlook is a tough one for Playa de Seaia. We’re looking at a solid 16-day window, but the first few days are a write-off. For the first week and a half, the conditions are just not cooperating. The wind is mostly onshore or cross-onshore, and the swell is either too small, too short-period, or both. You’ll see a lot of “poor surf conditions” flagged. There’s a bit of a gap from the start until we get to anything worth paddling out for.
The water temperature is sitting at 64°, which is a bit colder than normal for this time of year – about 2° cooler than average. So definitely grab a decent spring suit if you’re heading out.
Now, the first real glimmer of hope shows up on Sunday morning, 9th August. The wind is glassy, calm, and the swell is 2ft from the NW with a period of 10 seconds. The combined energy is moderate (130). It’s surfable, but very ordinary. The same kind of pattern repeats on the Monday morning, 10th August, and Tuesday morning, 11th August – clean, glassy conditions with ankle-to-knee high waves. It’s not going to be epic, but if you’re desperate for a slide, those mornings are your best bet.
The standout window, if you can call it that, arrives on Sunday, 16th August. The morning has a 4ft swell from the WNW with a period of 8 seconds, and the wind is a light cross-offshore. The combined energy is moderate (177), and it’s described as “clean.” That’s the best we get. The afternoon sees the wind pick up to 12 mph, which will mess it up.
After that, the swell picks up but the wind stays bad. Monday, 17th August afternoon gets a bump to 4ft, but the wind is cross-onshore and choppy. By Tuesday, 18th August, the swell jumps to 7ft from the N, but it’s onshore winds at 15-22 mph. The combined energy is strong (600-621), but it’s a messy, blown-out mess. At that size and with those winds, this is more of a kite session than a paddle session.
So, to sum it up: There are no true standouts here. The best on offer is the Sunday morning, 16th August, with a clean 4ft WNW swell. It’s not going to be a day to remember, but it’s the closest thing to a decent wave in the whole forecast. The rest is either too small, too windy, or too messy.
Rusty.

Information about the Playa de Seaia Surf forecast
The above surf forecast table for Playa de Seaia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Playa de Seaia can be found by selecting the local surf guide option on the grey menu. Our Playa de Seaia surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Playa de Seaia) regularly then make a mental note of the wave energy from the surf forecast table each time you go. 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. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
