The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Troia over the next couple of weeks. Gotta be straight with you, this one’s a tough read.
The whole 16-day window is a bit of a desert. There’s no real swell to get excited about, and conditions are mostly cross-shore or onshore. We’re looking at a long stretch where the surf will be flat or just plain poor. The first hint of anything even remotely rideable isn’t until the early morning of Friday, August 1st, and even then, it’s tiny.
The only time we see a little pulse of energy is the afternoon of Wednesday, August 6th. The swell picks up to about 4ft from the WNW, but with a period of just 5 seconds, that’s windswell, not groundswell. The combined swell energy hits 83 (moderate wave energy). The problem? The wind is a moderate cross-onshore, making things choppy. It’s not going to be clean. Later, on the morning of Thursday, August 7th we get a reprieve with clean conditions and a cross-offshore wind, but the swell drops right back to a knee-high 2ft.
If I’m being honest, the best looking morning in the whole run might be Sunday, August 10th. The wind is a fresh 19 mph from the NNW and cross-offshore, keeping it clean. There’s a 3ft swell from the WNW (period 5 seconds, combined energy 55), but it’s going to be lined up best for the experts given the size. The water temp is sitting at a very unusual 73°, which is much warmer than normal for this time of year.
Overall, there’s no standout window here. It’s a classic blank run for this area, with very few consistent options. We don’t tend to see this kind of prolonged flat spell too often, but when it happens, it’s best to save the wax for another day. The afternoon of the 6th might have the most energy, but it’ll be an ugly one.
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.
