The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this forecast for Troia is a tough one. We’re looking at a long, dry spell with barely a ripple for the better part of two weeks. The water is sitting at a touch warmer than usual for this time of year, about 72°, which is a degree or so above average, but that’s about the only bright spot.

We’re kicking off on Saturday, 29 August, and honestly, there’s nothing doing. The energy is a flat zero (0), with no swell to speak of. This stretch of poor conditions runs right through the first week. We get a tiny 0.3 ft of west swell showing up on Sunday afternoon, but with only 3 units of energy, it’s barely a bump. The same story plays out all the way into the first week of September – tiny slivers of swell, never breaking 0.7 ft, and the combined energy peaks at a measly 28 (moderate energy, just barely) on Tuesday morning, 1 September. Wind is mostly cross-off or light, so the surface is clean, but there’s simply nothing to ride. It’s a cruel flat spell for a spot that’s only “fairly exposed” to the SW.

We do get a slight pulse of interest around Wednesday, 9 September. That morning, the swell jumps to 2 ft from the NW, with the combined energy reading 30. It’s small, but it’s the biggest we’ve seen. The period is a short 5 seconds though, so it’s weak, windswell junk. Still, with a light cross-off breeze from the north, the surface is clean. It’s not a standout by any means – far from it – but it’s the closest we get to a wave. For a beginner-friendly spot that’s inconsistent at the best of times, this is a real bare run. The rest of the second week is dead flat again, with zeros across the board.

Look, if you’ve got a kite, you might get a puff on those breezy afternoons, but for a paddle surfer, there’s nothing worth chasing. It’s a blank run that’s pretty normal for this area when the swell windows close up. Forecasts can change, but right now, don’t bother waxing up.

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.
