The Lowdown
G'day, it's Rusty here. Honestly, I've got to be straight with you – the next 16 days are looking like a total write-off. There's just not a single proper surf window on offer for Troia. The swell is limp, the wind is messy, and it's one of those times where you're better off finding something else to do.
The whole pattern starts flat and stays flat. The first few days from Sunday the 19th have tiny, weak waves with a combined energy that barely gets above 26 (26) – that's just a ripple. The wind is a constant cross or cross-on mess, making it choppy and ugly. By Tuesday morning the 21st, the energy drops to a pathetic 4 (4). There's a bit of a bump on Thursday the 23rd afternoon, with swell hitting 4ft from the WNW, but the energy is still only 64 (64) and the wind is cross-shore, so it's just a bumpy, weak close-out. The rest of the month is the same story: clean mornings with zero swell, and afternoons blown out by onshore winds. The water temp is about average for this time of year.
The only real "standout," if you can call it that, is the morning of Thursday the 23rd at Troia. The swell is a tiny 2ft from the NW, but the wind is cross-off from the North at 10 km/h, which will keep it glassy and clean. The energy is still only 30 (30), so it's a longboard or a foamie wave. The break is inconsistent, so you'll be waiting around, and crowds are possible. But for a clean, calm session on the water, it's about as good as it's going to get across these two weeks. I wouldn't paddle out for anything else.
So, bottom line: the surf is a big fat zero for the foreseeable future. It's a quiet time of year for this area, so a blank run like this isn't a huge surprise. Keep an eye on it, because forecasts can change, but right now, leave the boards at home.

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.
