The Lowdown
G’day, Rusty here. Let’s be straight with you—this outlook for Troia is a bit of a tough one. Over the next 16 days, there’s barely a ripple worth paddling for. The waves are small, the periods are short, and the quality is just not there. You’re looking at a long stretch of flat or close-to-flat conditions, with a few tiny bumps that won’t get your heart racing. The first real chance of anything surfable doesn’t show up until Thursday the 23rd of July, and even then, it’s pretty ordinary. There’s a gap of several days with no recommendations at the start, so don’t rush to wax your board just yet.
The water temp here is about average for the time of year, nothing wild to report.
If you’re desperate, Troia (Troia) on the morning of Thursday the 23rd of July might just give you a slide. You’ll see a small northwest swell pushing in at 3 ft, with a period of 6 seconds—that’s a short, weak windswell, not a proper groundswell. The combined energy is only 63, which is weak. The wind is from the NNW at 6 mph, cross-offshore, and the morning is clean. That’s the best you’ll get, but it’s still a “surfable but very ordinary” kind of day. The swell direction is northwest, which is close to the optimum SW for this spot, so it’s not a total mismatch. But honestly, it’s small, inconsistent, and likely to be crowded sometimes.
The rest of the window is a write-off. Most days are flat with zero energy, or have tiny waves under 2 ft with poor wind and chop. The afternoon of the 23rd gets a bit bigger at 4 ft, but that’s from the WNW with a cross-shore breeze and a cross-chop—messy. No standouts after that, just more flat spells and a few tiny pulses from the south with long periods (12-15 seconds) but no height to speak of, so they’ll barely break.
For beginners, there’s nothing here—even the 4 ft on the 23rd afternoon is too small to be fun, and the wind is onshore. Experts would be bored. Honestly, this stretch looks more interesting for a kite surfer than a paddle surfer, with the clean morning winds but no swell.
Keep your eyes on the forecast, but right now, I’d say take a week off. It tends not to stay poor for long, but this run is a real bummer.
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.
