The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day outlook for Troia is a tough one to write. There’s just no good surf on offer for the entire stretch. The first usable bump doesn’t even show up, and honestly, the whole period is a write-off. We’re looking at a solid 16-day gap where not a single session is worth paddling out for.
The water is sitting at 74°F and that’s a whopping 5°F warmer than what’s normal for this time of year – that’s very unusual, practically bathwater, but it doesn’t help when there’s no energy to push it around.
For the first week, from Wednesday the 5th right through to Tuesday the 11th, the swell is either totally flat or bumping around a pathetic 0.3ft to 4ft. The combined energy of all swells directed here barely scratches double digits, with the highest reading being a weak 73 on the 6th. That’s not even enough to get a ripple on a pond. The period is mostly short, between 4 and 6 seconds, so even the tiny bits of swell are just wind slop. The wind is mostly cross-off or cross, which would keep it clean, but there’s simply nothing to ride.
The second week doesn’t get any better. From Wednesday the 12th through to Thursday the 20th, we’re looking at the same story. The few tiny 0.3ft to 0.7ft pulses that come through from the south or southwest have long periods of 13 to 17 seconds, but the energy is still in the toilet – the combined energy only touches 21 on the 19th and 20th. That’s weak. With a long-period groundswell of that size, it’s almost like a ghost – you can see it on the buoy, but it just doesn’t have the height to stand up. The winds turn fresh on the 14th with 22 mph from the NNW, and that’s more of a kite-surfing breeze than anything for a paddle board.
The only break in the mix is Troia, and it’s an inconsistent beginner spot that’s fairly exposed to the southwest. It’s a beach setup, and with these tiny, weak swells, it’s not breaking. The crowds are listed as “sometimes,” but that’s a non-issue when there’s no surf. The pattern here is brutal – a solid 16 days of nothing. It’s the kind of run that happens in this area, and you just have to wait for the forecasts to change.
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.
