The Lowdown
Alright, Rusty here. Let's be straight with you about Troia. It's a flat spell, and I mean flat. The outlook for the next 16 days is a tough one for anyone looking to paddle out. The water is running a ridiculous 77° right now, which is a whopping 8° warmer than usual for this time of year – that's proper tropical, but the ocean is a millpond.
Looking at the first week, from Monday the 20th of July right through until the end of the month, there's just nothing doing. The swell is tiny, often under 2ft, and the period is all over the place – mostly short, choppy stuff. The energy is weak, with values stuck in the single digits (10) most days. Tuesday the 21st starts glassy in the morning, but the swell is only 0.7ft, so it's a mirror. The afternoon picks up a cross-on breeze that just messes up the 2ft of slop. The only clean windows come from the cross-offshore winds on Thursday the 23rd morning and Sunday the 26th morning, but the swell is still 0.3ft or less. There's a bump on Sunday afternoon the 26th, with a 5ft swell from the NW, but it's got a 19 mph cross-offshore wind and the combined energy jumps to 111 (moderate), but the guidance still calls it poor surf. For a beach break like Troia, that 5ft with a short period (5 seconds) and strong wind is just messy, probably more interesting for kite surfing than a paddle surf.
The second week doesn't get much better. There's a long gap from Monday the 27th through to Thursday the 30th of July, with several days of zero swell. We finally see a tiny pulse on Friday the 31st of July, with a 1ft WNW swell, but it's a 3-second period, so it's just wind chop. Saturday the 1st of August and Sunday the 2nd see a bit of a rise, with clean cross-offshore winds, but the swell is still only 3ft at best, and the energy is still low (16). The best chance in the whole window looks like Monday the 3rd of August, with a clean 3ft NW swell and a 19 mph cross-offshore breeze. The combined energy is 49 (weak), but it's the most consistent-looking day. Still, it's nothing to write home about.
Honestly, the whole 16-day window is a write-off. The breaks are inconsistent, the swell is mostly absent, and when it does show up, the wind or the period kills it. It's a blank run, and for this area, that's just how it goes sometimes. Forecasts can change, but right now, I'd leave the boards 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.
