The Lowdown
Alright lads, Rusty checkin' in. Looking at the Troia zone, and I hate to be the bearer of bad news, but the surf is a no-show. This whole 16-day window is a bust. There's just nothing worth paddling out for.
Starting on Saturday, August 15th, it's flat. We're talkin' 0.3ft of weak southern swell. The wave energy is laughable, barely registering. You might get some glassy mornings – like Wednesday the 19th with a slight southerly breeze, or Thursday the 20th – but it's like a lake. The water temps are a massive 7° warmer than usual, sitting at 75°. Unusual, but not much good without waves.
This pattern doesn't change. We get clean cross-offshore winds on the 22nd and 24th, but on swells that wouldn't even tickle a longboard. The biggest bump we see is on the 25th: 3ft from the NW, but with a short 5-second period and weak energy. Still a total dud. This run of nothing-burgers lasts right up until the 29th.
There's a tiny, last-ditch pulse on Sunday, August 30th – 2ft from the NW. But with a short period and onshore wind, it's gonna be a choppy, messy mess.
So there it is. Sixteen days of flatness. There's no stand-out session, no hidden gem. It's just one of those spells. Forecasts can change, but right now? Save the petrol and wax a board for another day.
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.
