The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cooking for the Troia area over the next couple of weeks.
To be brutally honest, the forecast is a tough one to swallow. Right now, we’re looking at a long stretch of flat or near-flat conditions. There’s a gap from the start of the period all the way through to around the 7th of September with nothing worth paddling out for. The swell is just not showing up, and the small bumps we do see are too weak to break properly. Expect a lot of clean, glassy mornings with zero energy – frustrating if you’ve got the itch.
The first real pulse of swell tries to show on Monday the 7th of September, but it’s a messy, short-period NW windswell at 3ft with a period of only 4 seconds. That’s poor quality stuff, and with a cross-shore wind, it’s going to be a chop-fest. Not your day.
The best we can honestly call a standout is the morning of Wednesday the 9th of September. You’ll see a tiny 3ft NW swell with a period of 6 seconds, and the wind is a clean cross-offshore from the north at 12 mph. The combined wave energy is weak (47), so it’s not going to be epic, but for Troia, that’s about as clean as it gets in this gloomy forecast. The break is inconsistent, so don't expect a wave every minute, but if you’re a beginner looking for a safe, small, clean roll, that’s your window.
The rest of the outlook is grim. From the 10th of September right through to the end of the 16-day window, we’re back to tiny 0.3ft to 0.6ft swells from the south or west, with periods all over the place. The combined energy sits in the single digits – basically a lake. The water temperature is about average for this time of year, so no surprises there. There are a few glassy mornings, like on the 14th, 15th, and 20th of September, but with no swell to speak of, it’s just a pretty view.
Overall, if you’re set on surfing, aim for the 9th of September morning. Otherwise, save the petrol. The setup here is more interesting for a kite surfer on the few days we get a bit of cross-shore breeze, but for a surfer, it’s a long wait.
Rusty.

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.
