The Lowdown
Alright, let’s get straight into it. We’re looking at Troia here, and honestly, it’s a quiet stretch. The whole 16-day window is a bit of a flat spell, with nothing really getting going. The swell energy is weak, mostly sitting in the single digits or low double digits, and the wave heights barely tickle the knee. The best we can say is that there are a few moments where the wind cleans up, but the ocean just isn’t cooperating.
Kicking off on Wednesday the 15th, the morning’s glassy with a tiny 0.3ft SW swell at a long 12 seconds, but it’s a dud – only 6 combined energy. The afternoon picks up a cross-onshore breeze, and it’s choppy. Not much to write home about.
Thursday the 16th stays small, with a 0.3ft S swell and the wind turning cross–onshore in the afternoon, making it messy. The energy is still next to nothing.
Friday the 17th is the first real glimmer. The morning sees a light cross-offshore breeze from the NNW, and the swell nudges up to 1ft, but it’s a short-period 6 seconds from the W. The combined energy is only 15, so it’s weak. The afternoon brings a bit more size at 3ft from the WNW, but the period drops to 4 seconds – that’s just wind chop. The clean conditions in the morning are the only saving grace.
Saturday the 18th is similar. Morning clean with a light cross-offshore, 2ft NW swell at 5 seconds. The afternoon gets a bit bigger at 3ft (WNW, 4 seconds) but the wind turns cross-onshore and it gets choppy. Energy hits 46 in the afternoon, the highest we’ve seen so far, but the period is too short for any real shape.
Sunday the 19th is a step back. The morning is tiny with a 0.3ft W swell, and the afternoon is a windy, onshore mess at 3ft. The energy is 38, but it’s blown out.
Monday the 20th, Tuesday the 21st, and Wednesday the 22nd all follow the same pattern – small, short-period swells, and the wind is either cross or onshore. The only highlight is Tuesday the 21st afternoon, where the swell hits 4ft from the WNW at 4 seconds (53 energy), but it’s choppy and cross-onshore. No good.
Thursday the 23rd afternoon is worth a mention. The wind goes clean and cross-offshore from the NW, and the swell is 4ft at 5 seconds from the NW, with 56 energy. That’s the cleanest combo we get in the entire forecast. The waves will be small but clean, so for a beginner or someone on a longboard, it’s the most surfable moment. The break is inconsistent here, so don’t expect a lineup, but it’s the pick of the bunch.
From Friday the 24th through to the end of the month, the trend holds – small swells, short periods, and moderate to fresh winds. The energy stays below 100 the whole time, often in the teens or twenties. The water temp anomaly is about average for the time of year, so nothing unusual there.
In short, Troia is a flat spell. The best window is probably Thursday the 23rd afternoon, with clean conditions and a knee-high swell. For the rest of it, you’re waiting on a change that isn’t coming in this 16-day outlook. Crowds are possible around the cleaner windows, but honestly, with this little action, it’ll be quiet.

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.
