The Lowdown
G'day, Rusty here. Look, I've got to be straight with you – the next 16 days are a tough sell for surf around Troia. The forecast is a long, flat spell with nothing to get excited about. There's a big gap from now until the very end of the run, with day after day of "poor surf conditions" and minimal energy. The water's sitting at about 72°, which is a touch warmer than normal for this time of year, so at least a swim won't be freezing.
The first proper sign of life doesn't show up until the afternoon of Tuesday, 10 September, and even then it's a whisper. On Thursday morning, 12 September, we finally see a tiny pulse of swell. It's not much – a 2ft swell from the WSW with a short period of 6 seconds, giving a combined energy of just 36 (weak). The wind is light and cross-offshore from the NNW early on the 12th, so the conditions will be clean. But honestly, a 2ft, 6-second wave is barely a ripple. It's a beginner's wave at best, and with the break being inconsistent, you'd be lucky to find a rideable bump.
After that, it fades back to nothing. The rest of the week into the weekend is flat, with barely any energy (reading as low as 3). The wind stays variable, but it doesn't matter when there's no swell. This is a blank run, and for this area, it's not unusual to see such a stretch of nothing. The whole setup looks more like a day for a kite than a paddle, if you're into that sort of thing.
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.
