The Lowdown
Alright, let me tell ya how it is for Troia over the next couple weeks.
Honestly, mate, it's a tough stretch. We’re lookin’ at a real flat spell here, with a big gap of nothin’ to get excited about. The forecast opens with a score of zero for Sunday the 9th, and that pretty much sets the tone for days to come. We’ve got a long stretch of very weak, poor quality surf conditions rollin’ through, with a combined swell energy stuck at zero for much of the first week. The water’s sitting at a notable 73°, which is much warmer than normal for this time of year, but that’s about the only thing out of the ordinary.
We see a little blip of energy around Monday the 11th afternoon with a weak 3ft swell from the WNW, but it's a short-period 4 second wind swell with only 42 units of combined energy – that’s weak. Winds are cross-on, so it’s not gonna be pretty. Tuesday the 12th and Wednesday the 13th are flat again with clean mornings but zero swell.
There’s a tiny pulse that shows up Friday the 14th, but we’re talkin’ about a 0.3ft groundswell from the south with a 12-second period, and the combined energy is a measly 3. That’s barely a ripple, and with cross-off shore winds in the morning, it might look clean, but there’s nothin’ to ride. That same tiny energy pattern hangs around for days, barely reachin’ 33 units of combined energy by Thursday the 20th afternoon. The winds are mostly onshore or cross-onshore from the SW, which just messes up what little is there.
This break is inconsistent at the best of times, and this run is a prime example of a blank period that’s pretty normal for the area. Honestly, this setup is lookin’ more interesting for kite surfing than for paddlin’ out, as the onshore winds and tiny chop will at least give them somethin’ to work with. For us surfers? It’s a long wait.

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.
