The Lowdown

Alright, let’s get this straight. I’m looking at the whole 16-day window for Playa de Seaia, and truth be told, it’s a pretty flat run for a while. There’s no real stand-out surf to get excited about for the first week or so. The first few days are tiny, weak, and mostly blown out or just plain ordinary. It’s not until we get into the second week that things start to look a bit more promising, but even then, it’s not fireworks.

The first real surfable session I can see is on Wednesday morning, the 15th of July. We’ve got a tiny 2ft swell from the west, with a period of 9 seconds. The wind is glassy, so it’ll be clean, but the energy is really low (73). The water’s sitting at 62°, which is a bit colder than normal for this time of year, so you’ll want a decent wetsuit. That morning is the best of a pretty poor bunch for the first few days.

After that, the 16th through the 19th is a write-off. We’ve got onshore wind, choppy conditions, and the swell is either too small or too messy. Saturday morning the 18th shows a jump to 3ft from the NNE, but with a short 6-second period and onshore wind, it’s just a messy, weak windswell. Not worth paddling out for.

Monday the 20th has a glassy morning with 5ft from the NNE, but it’s still a short period and the energy is moderate (261). It’s surfable, but very ordinary. The afternoon gets bigger to 7ft, but the wind goes cross-onshore, so it’s blown out.

The real standout, if you can call it that, is looking like the final weekend. Saturday the 25th of July morning has a glassy setup with a 2ft swell from the WNW, but the period is a nice 11 seconds. That’s a proper groundswell, and the energy is moderate (157). The wind is glassy, so it’ll be clean. That’s your best bet for a clean, fun wave on a longboard or a fish. The afternoon also stays clean with a cross-offshore breeze. Sunday the 26th morning has offshore wind again with a 2ft, 9-second swell from the WNW, and the energy is similar (164). It’s not big, but it’s clean and workable.

Tuesday the 28th and Wednesday the 29th get a bit more size, up to 5ft, but the wind is onshore or cross, and the period is short, so it’s messy. The energy gets up there (293, 486), but the quality is poor.

The very last day, Thursday the 30th of July morning, has a 5ft swell from the NNW with a long 11-second period, and the energy is strong (578). But the wind is cross-onshore, so it’s not going to be clean. If that wind swings, it could be something, but as it stands, it’s marginal.

Overall, for Playa de Seaia, the best is that Saturday the 25th and Sunday the 26th. Clean, glassy or offshore, with a little groundswell. It’s not pumping, but it’s your best chance for a decent session. The rest of the window is pretty average to poor.

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.
