The Lowdown
Alright, let’s have a look at what’s on the cards for the next couple of weeks.
Honestly, I’m not gonna sugarcoat it – this is a rough run for Troia. The forecast is looking pretty bleak for any decent surf. We’ve got a long stretch ahead with almost nothing to get excited about.
Starting off from Sunday the 19th of July, we’ve got a tiny bit of swell from the WNW, but it’s a messy 3ft with a short, weak period of 4 seconds and cross-onshore winds. The water is a warm 77°, which is much warmer than normal for this time of year, so that’s nice for a dip, but the surf itself is poor. The combined swell energy is a very weak 39. That pattern basically holds through the week – tiny waves, mostly under 3ft, with poor wind. Monday the 20th offers a 1.0ft wave from the west in the morning, but it’s cross-shore with a light breeze and only 8 seconds of period. Not worth paddling out for.
There’s a slight glimmer on Thursday the 23rd afternoon, with a 3ft wave from the WNW, but again, it’s a short 4-second period and cross-shore, leaving it choppy. The energy is still weak at 37. Friday the 24th afternoon sees a bit more height at 4ft from the WNW, but the period is still a poor 5 seconds, and it’s a moderate cross-shore chop. Energy climbs a little to 61, but it’s still weak.
The best we get in this whole outlook is on Sunday the 26th of July. The morning is flat, but the afternoon brings a 5ft swell from the NW with a 6-second period. The wind is cross-offshore and it’s clean. The combined energy hits 154, which is moderate. That’s the biggest surf of the window, but it’s short-period and a bit much for beginners at over 5ft. Monday the 27th afternoon is similar, with another 5ft from the NW and 159 energy, but the wind turns cross-shore, making it lumpy.
After that, it drops right off. From Tuesday the 28th afternoon through to Monday the 3rd of August, we’re looking at flat spells, tiny 0.3ft waves, and mostly onshore or cross-offshore winds with no real energy. There’s a glassy morning on the 2nd of August, but there’s no swell at all.
The advice here is simple: leave the board at home. This setup is more interesting for kite surfing than paddle surfing on the days with wind and a bit of chop. The only standout, if you can call it that, is the afternoon of Sunday the 26th of July – that’s your best shot for a clean, chest-high wave with cross-offshore wind, but it’s short period and won’t be world-class. Anything beyond that is a gamble.

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.
