The Lowdown

Alright folks, Rusty here. Let’s have a look at what Playa de Seaia has in store for us over the next couple of weeks.

Right off the bat, we’re looking at a pretty grim opening. The first few days are a write-off – strong onshore winds and junky, poor surf conditions. You wouldn’t want to be out there. Friday the 31st of July through to Saturday the 1st of August is a total no-go, with messy, blown-out waves and a raw, weak energy reading (54 to 166). It’s just not worth it.

Things finally start to look a little more promising on Sunday the 2nd of August. Sunday morning is the first real glimmer of hope. We’ve got a glassy, dead-calm morning with a light swell bumping up to 2ft from the west, with a 10-second period. The energy is still modest (124), but the clean conditions will make it feel much better than the numbers suggest. It’s an early morning, small-wave session for the beginners. The afternoon stays clean but the wind swings cross-on, dropping the energy right down.

Monday the 3rd of August morning is another solid little window. Southwest offshore wind at 3 mph, with 3ft of west swell and a clean surface. The energy is moderate (118). You’ll be sharing the water with a few others – crowds are “sometimes” an issue here – but it’s a fun, user-friendly wave for a beginner.

Tuesday the 4th of August morning repeats the trick: clean, light offshore winds and 3ft of west swell. Tuesday afternoon gets a bit lumpier with the wind picking up.

The standout of the whole run, if you can call it that, is probably Wednesday the 5th of August morning. It’s glassy again, absolutely flat calm, with a small 2ft west swell. The energy is low (74), but you’ll be surfing in perfect, mirror-like conditions. It’s more about the tranquility than the power.

After that, it’s a slow fade. The rest of the first week and into the second week offers a mix of onshore winds and *surfable but very ordinary* stuff. The swell stays small, generally under 3ft, and the energy readings hover around the 100-176 mark – nothing to get excited about. There’s a brief moment on Tuesday the 11th of August morning with a gentle offshore wind and a clean 3ft wave, but it’s not a game-changer. Crowds are possible.

Honestly, there’s no real “best on offer” here. The entire 16-day window is a slow, small-wave period. The water temperature is about average for the time of year, nothing unusual. For a beginner looking to get some clean, small waves on a longboard, the Sunday the 2nd and Monday the 3rd mornings are your best bet. For anyone else, it’s more of a “check the forecast again in a few days” situation.

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.
