Playa de Seaia Surf Forecast and Surf Report

Alright, Rusty here again. Let’s break down Playa de Seaia in feet and miles per hour. It’s a quiet outlook, I’ll be straight with you. The first half of the 16 days is mostly flat or poor, with a few windows that are worth a paddle, but nothing to get stoked about. The water is running at 63°F, a bit colder than usual for this time of year, so you’ll want a wetsuit.

The first chance to get wet is Monday the 3rd of August. We’ve got a small 4ft swell from the west, with a period of 8 seconds, so the energy is weak (155). The morning is the best bet: light SSW wind at 6 mph, cross-off, and the waves are clean. The optimum swell direction is NW, so it’s not a perfect match but it’s rideable. The afternoon picks up a bit more energy (219) with a clean offshore wind at 12 mph, but the waves are still very ordinary. This is the best on offer for the first few days.

Tuesday the 4th is similar, with a 3ft swell in the morning and a gentle offshore wind from the SW at 9 mph. The period is 9 seconds, energy is moderate (141). The afternoon sees a 3ft swell with a cross-off wind, but it’s not great.

From Wednesday the 5th through the end of the first week, the wind turns onshore and the surf quality drops hard. The swell gets a bit bigger—up to 5ft on Thursday the 6th—but with onshore wind and poor conditions, it’s not worth your time. The energy ramps up but it’s messy.

There is a small window on Sunday the 9th of August. The morning is glassy with a 2ft swell from the NNW, period of 9 seconds, and very low energy (71). The wind is almost nothing. It’s surfable but very ordinary. That’s the last decent moment until the second week.

The second week sees a few more opportunities. Tuesday the 11th has a morning with a 3ft swell from the NNW, period of 10 seconds, and a clean offshore wind from the WSW at 3 mph. The energy is moderate (178). The afternoon picks up to 5ft from the NNE with a short period of 5 seconds, but the wind is cross-off and clean. Not great shape, but ridable.

Wednesday the 12th is interesting: the morning is glassy, zero wind, with a 3ft swell from the NNE but a very short period of 5 seconds. The energy is low (99). It’s clean, but the swell is weak and short. The afternoon gets a bit more size (5ft) but the wind turns cross-on.

After that, from Thursday the 13th onward, the swell builds but the wind goes fully onshore and the conditions turn poor. By Friday the 14th, we’re looking at 7ft to 8ft waves from the NNE with a short period of 7 seconds and onshore wind at 12–16 mph. That’s a lot of energy (505–677) but it’s a messy, blown-out mess. Not for beginners, and only for experts who don’t mind a battle. The wind is strong and onshore, and the beach setup means it’s more likely to be a kite-surfing show than a clean paddle session.

The last few days from the 16th to the 18th drop off again, with small, weak, and poor conditions.

Overall, the standout is the Monday morning (3rd of August) and Tuesday morning (11th of August) for the cleanest, most rideable conditions. The glassy Wednesday morning (12th) is also worth a look if you’re desperate for a clean, small wave. Nothing here is going to blow your mind, but there’s a few moments to get wet.

Rusty.
