The Lowdown
Alright, this is Rusty checkin' in with a look at the surf prospects for Troia over the next couple of weeks.
First off, I gotta be straight with you – it’s gonna be a long, dry spell. The outlook is pretty flat for days on end. We're talking a stretch with basically nothing rideable from the get-go, and it's not looking to change anytime soon. Honestly, for this stretch of coastline, a blank run like this isn't totally unexpected. It happens. We just gotta wait for the weather patterns to shift.
The first real day on offer, Tuesday the 11th, is the closest thing to a pulse, but it's a weak one. You're lookin' at a 2 ft NW windswell with a super short 5-second period – that's all chop and no drive. Wave energy is a measly (15). The morning has light N winds blowin' cross-off, which keeps things clean, but there's just no power behind it. By afternoon, the wind swings WSW and goes cross-on, making it even messier with a 3 ft WNW swell, but the period drops to 4 seconds. Energy only climbs to (38), but with that quality, it's a no-go. This is really just a kite-surfing breeze, not paddle surfing.
From Wednesday the 12th right through to the end of the forecast on the 26th of August, it’s a ghost town. Swell heights are barely registering, with most days showing less than 1 ft slop. The combined wave energy rarely gets into double digits, and even when it does – like the 27 on Tuesday the 18th or 28 on Thursday the 20th – it's from long-period southern swells that are way too weak and misdirected to break properly on this beach. The wind is often light and clean, with a few morning glass-offs around the 24th and 25th, but without any swell, it's just flat, pretty water. The long-period stuff (14-18 seconds) just won't wrap in with enough height to matter.
So, there's no standout session here. There's nothing to recommend. The best thing you can do is leave the boards in the car and enjoy a cold one on the sand. The water temp is about average for this time of year, so at least it's not uncomfortable to have a swim. Hang tight, buddies.
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.
