Table - best surf conditions forecast for Troia over the next 16 days.
Alright, Rusty here. Let’s have a look at this forecast.
To be straight with you, it’s a real dry spell coming up. Over the next 16 days, we’re looking at a whole lot of flatness. The first hint of anything ridable doesn’t come until the end of the first week. There’s a big, long gap of nothing at the start.
The only break on the menu is Troia. It’s an inconsistent beginner spot that gets a fair bit of swell exposure, but it’s mostly waiting for scraps. The water is a wild 75°F , which is nearly 7°F warmer than it should be right now. That’s a massive anomaly.
The first real chance to get a wave is Thursday afternoon, July 16th. We get clean cross-off wind from the N at 16 mph and a little pulse of swell – about 4 ft from the WNW with a short 5-second period. The energy is weak (92). You might find a little wave on a good tide, but it’s not great.
Friday morning, July 17th is the pick for clean conditions early, with a light N wind at 6 mph and a small 2 ft swell from the NW. The afternoon gets a little choppier with cross-shore wind, but the same small swell is there. Energy is still weak (28). For a beginner spot, these clean morning windows are your best bet.
Sunday afternoon, July 19th has a bit more going on. Clean cross-off NNW wind at 19 mph and the wave energy jumps to a moderate 118. The swell is 5 ft from the NW with a short 5-second period. Then Monday afternoon, July 20th has the biggest swell of the period at 6 ft from the NW and the strongest energy (181). But with that short period and the wind patterns, it’s going to be lumpy. Honestly, with clean cross-off winds and that short, punchy swell, this beach setup is looking more interesting for kite surfing than regular paddle surfing.
After that, the second week from July 21st to July 26th is completely flat. Swell is gone, energy is zero, and the wind is all over the place. There’s nothing to paddle for. If you really need to get wet, the morning of July 17th and the afternoon of July 19th are the least terrible options. But it’s bleak.
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.
