The Lowdown
Alright, grab your board and let’s talk about the next couple of weeks. It’s a bit of a slow burner for Praia Pequena, a fairly consistent little beach break that needs the right conditions to really light up. Right now, it’s not looking like a classic run, but there’s a real gem hiding in the second week if you’re willing to wait.
The first stretch is a write-off, unfortunately. From Tuesday the 4th all the way through to the 13th, it’s a battle. We’ve got onshore and cross-onshore winds from the north and northwest most days, and the swell is small and junky. The energy is weak, sitting in the low hundreds, with waves mostly around 1ft to 6ft. The period is short, around 6 to 8 seconds, which just means messy, crumbly lines with no push. The water is a bit colder than normal for this time of year, about 67°F, which is a degree off the average – you’ll feel that in a thicker wetsuit. There’s no point even looking at it until the wind swings around.
Things only start to change on Friday the 14th. The swell bumps up to 7ft from the NNW with a period of 8 seconds, but the wind is still all over it – cross-onshore, making it lumpy and poor. The energy jumps to 539, a real push of water, but it’s not clean. That day and Saturday the 15th are still frustrating. The morning of the 15th is the first real light in the tunnel. The wind goes light and cross-offshore from the south, the ocean cleans up, and you’ve got 7ft of NNW swell. It’s bigger, but the period is still short, so it’s going to be a bit walled. Still, it’s the first time you can actually surf without getting blown off your board.
But the standout, the one I’m genuinely excited about, is Monday morning, August 17th. This is the pick of the entire forecast. The swell is still solid at 8ft from the NNW, and the period has stretched to 8 seconds. The real kicker is the wind: a light cross-offshore breeze from the SSW. The conditions are forecast to be clean, and the energy is strong at 632. This is the day you want to be out there. It’s got size and shape.
The window doesn’t last long. The afternoon of the 17th turns cross-shore and messy. The 18th has more size but the wind is onshore again, spoiling it. And by the 19th, the swell is still big, but the northwesterly wind is howling, making it a complete mess. At nearly 7ft with a cross-onshore wind, Praia Pequena is going to be a washing machine. It might be more interesting for the kite surfers than us paddle surfers.
So, the plan is simple: keep your eyes on the morning of Monday the 17th. That’s your window. The forecast is a bit far out, so treat it as promising but not set in stone. The good news is, the swell is coming, and with the right wind, this place will fire. It tends not to stay this poor for long.
Stay stoked.

Information about the Praia Pequena Surf forecast
The above surf forecast table for Praia Pequena provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia Pequena can be found by selecting the local surf guide option on the grey menu. Our Praia Pequena 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 (Praia Pequena) 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 Praia Pequena 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.
Praia Pequena is 8 km (5 miles) from Sintra. If you plan a holiday in Lisboa, look for hotels and other accommodation in Sintra. Sintra has rooms for a wide range of budgets as well as car hire and transport links.
