Table - best surf conditions forecast for Troia over the next 16 days.
Alright, grab a coffee and listen up. Rusty here. Let’s look at what’s cookin’ for Troia over the next couple of weeks.
Straight up, I gotta be honest with you: the next 16 days are a tough watch. The surf is mostly flat, weak, and messy. There’s a big gap of nothing happening. The first real chance to even get wet doesn’t come until the morning of the 21st of July, and that’s a long stretch of flat water. Before that, from the 9th through to the 20th, it’s almost entirely poor surf conditions with tiny, wind-affected swell. You’ll see a few glassy mornings on the 11th, 12th, and 13th, but the swell is barely a ripple – 0.3 ft to 2 ft with short, weak period. It’s just not worth paddling out for that.
The one standout, and it’s a very small one, is the morning of 21st of July. The forecast is finally showing “surfable waves but very ordinary conditions.” The swell is 2.6 ft from the NW with a period of 6 seconds, giving a combined energy of 56 (moderate). The wind is a light NW cross-off that will keep it clean. It’s not gonna be a classic, but it’s the only time in the whole window where the score is above zero. Given the persistent lack of any real energy, this is your best bet, but keep your expectations low.
The water temp is around 75.2°, which is a massive 7.7° warmer than usual for this time of year. That’s very unusual and you’ll be sweating in your wetsuit or enjoying a warm bath, depending on how you look at it.
Before the 21st, the onshore winds and tiny swells are a write-off. After the 21st, it drops back to tiny 0.3 ft junk. Because Troia is a beach break, and the swell is so small and weak, the whole setup is better for a paddleboard than a surfboard. Stick to the plan for the 21st morning, or just wait for a new forecast.

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.
