The Lowdown
Right, folks, Rusty here. Let's have a look at what Troia’s got cooking for the next couple of weeks. I’ll be straight with you – it’s a pretty grim outlook. The finder is showing no recommendations at all for the entire 16-day window, which is a real bummer.
We’re staring down the barrel of a long, flat spell. The first sniff of anything that might be called a wave shows up on the afternoon of Thursday the 6th, but it’s a short-period, messy windswell from the NW, hitting 5 ft. That’s the biggest number we’ll see, but with a period of just 5 seconds, it’s going to be a bumpy, unpredictable mess. The cross-offshore wind will keep the surface clean, but with such weak energy (114), it’s more of a frustrating close-out than anything rideable.
The rest of the fortnight is a desert. From Sunday the 2nd through to Monday the 17th, every single entry is marked as “poor surf conditions.” We’re talking about a solid 16-day gap with nothing worth paddling out for. There are a few moments of glassy conditions on the mornings of the 12th, 15th, 16th, and 17th, but with zero swell to go with it, it’s just a flat, pretty ocean.
The water temperature is a huge talking point. It’s sitting at 74°, which is a whopping 6° above normal for this time of year. That’s seriously unusual – it’s like the ocean has forgotten what season it is.
For a spot like Troia that’s inconsistent at the best of times, this kind of blank run is a tough pill to swallow. Don’t hang your hopes on this one. It’s a waiting game. Forecasts can change, but as it stands, leave the boards in the van.
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.
