The Lowdown
Alright, Rusty here. Let’s get straight to it.
Well, folks, I’ve got to be honest with you – looking at this 16-day stretch for Troia, the news isn’t good. There’s simply no surf on offer. Not a single day with a wave worth paddling for. The whole run is a flat spell, with the combined swell energy barely ticking over – we’re looking at values mostly between zero and 47, which is about as weak as it gets. The first real flat day starts now, and the only tiny blips of movement are from swells under 0.7ft, which is nothing but a ripple. This kind of blank run is more normal for this area when the swell window just isn’t lining up.
For the one spot we’ve got here, Troia, it’s an inconsistent beginner break that rarely sees any action. The water temperature is sitting at a very unusual 74°, which is much warmer than normal for the time of year – almost 5 degrees above average, so you can expect a warm bath with no waves. The only faint pulse comes from a long-period south swell (18 seconds) on the morning of Saturday the 15th, but it’s only 0.3ft and straight onshore by the afternoon, so it’s not even a ripple. On Sunday the 16th morning, we get a glassy moment with a 0.3ft SW swell, but again, zero push. The whole setup looks more interesting for a kite surfer if the wind picks up, because for paddle surfing, there’s just nothing to ride.
If you’re hanging for a wave, keep an eye on the charts – it tends not to stay this flat forever, and forecasts can change. But for now, leave the board at home.

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.
