The Lowdown
Alright, surfers, Rusty here. Let’s have a look at what’s cooking for the Troia area. Gotta be straight with you from the start—this 16-day window is a real tough one. We’re looking at a long, dry spell with barely a ripple worth paddling for. The first real chance of anything doesn’t show up until the first of August, so we’ve got a solid week and a half of flat or junk conditions to sit through.
The overall pattern is dominated by light, variable winds and tiny, short-period swells that just don’t have any push. The combined swell energy is almost always in the low double digits, like 4 or 23, which is barely a whisper. There’s a lot of cross-shore and cross-onshore breezes, just messing up what little texture there is. For the first week, from Wednesday the 22nd right through to the end of July, it’s a write-off. The water temp is about average for the time of year, nothing wild to report.
Come Saturday morning, the 1st of August, we finally see a glimmer of hope. The morning session is the only real standout in the whole period. Troia will see a light, clean cross-offshore breeze from the north at 9 mph, with a northwest swell pushing in at 4 ft, though with a short period of 6 seconds. The combined energy is a moderate 76, which means there’s finally some actual push in the water. The waves will be surfable, but they’re ordinary—nothing to write home about, but it’s the best we’ve got. The afternoon turns to junk again with a cross-onshore wind.
After that glimmer, it’s back to the doldrums. The rest of the first week of August is another flat spell with tiny or non-existent swell and clean but useless conditions. The pattern is clear: it’s a lean season for Troia.
So, if you’re desperate, the morning of Saturday the 1st of August is your only real shot. It’s not going to be epic, but it’s the only window with a clean, rideable wave. The rest of the time, leave the board at home.
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.
