The Lowdown

Alright, let me tell you straight up – the next couple of weeks here in Troia are lookin’ pretty grim for ridin’ waves. Honestly, for the first ten days or so, there’s just nothin’ on the table worth paddlin’ out for.

The first real whisper of life doesn’t show up until the 27th of September. Sunday morning, the wind is light cross-onshore out of the West, but we finally get some swell: about 6ft from the West, with a period of 10 seconds. The combined energy jumps to a moderate 533, so there’s some push there. That’s a bit of a relief after all the flatness. But be warned – that afternoon, the wind swings onshore from the SW, so the window is tight. It’s not perfect, but it’s the only real swell in the whole run, and it might be worth a look for the die-hards.

After that little pulse, it goes quiet again for a bit, but then Tuesday the 29th of September serves up something a little better for the morning. Glassy conditions out of the WNW, with a 4ft West swell and a short period of 7 seconds. The energy is moderate at 124, so it’s surfable but nothin’ to write home about. The afternoon turns crummy again with onshore wind, so the morning session is the only call.

Look, the bottom line is: if you’re keen, keep an eye on the morning of the 27th. That’s your best chance for a wave with a bit of size. The rest is mostly small, weak, and messy. Crowds at Troia are always a possibility, but with this forecast, I doubt you’ll have to fight for ‘em.

Information about the Troia Surf forecast

The above surf forecast table for Troia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Troia can be found by selecting the local surf guide option on the grey menu. Our Troia 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 (Troia) 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 Troia 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.

Troia is 9 km (6 miles) from Setubal. If you plan a holiday in Portugal - Alentejo, look for hotels and other accommodation in Setubal. Setubal has rooms for a wide range of budgets as well as car hire and transport links.
