The Lowdown
Alright, Rusty here. Let's talk about Troia.
Honestly, looking at the next 16 days, it's a pretty flat and quiet picture for Troia. The first real surfable wave doesn't even show up in the forecast. We've got a long stretch of nothing – from Tuesday the 28th of July all the way through to the morning of Thursday the 6th of August – where the ocean is just not giving us any rideable swell. You'd be looking at a glassy, flat lake for most of that time. The water temperature is a very warm 73°, which is much warmer than normal for this time of year, but that's about the only thing going for it.
The first whisper of something happens on the afternoon of Thursday the 6th of August. The wind will be a fresh cross-shore from the NW at 19 mph, which will make things lumpy and choppy. The swell picks up to 5ft from the NW with a short period of 5 seconds, giving the water a combined energy of 118. That's a moderate amount of energy, but that short period and the strong onshore/cross wind are going to make it a messy, blown-out affair. It's not a recommendation for a good surf, but it could be interesting for the kite surfers if you're into that.
After that, it's back to tiny, un-rideable conditions for the rest of the period. The morning of Friday the 7th of August stays clean with a tiny 0.3ft south swell, but that's not enough to paddle for. The afternoon of Sunday the 9th of August brings a tiny 0.3ft W swell with a 10-second period, and the morning of Monday the 10th of August has a 0.7ft W swell with a 12-second period – still too small. The last mention of anything is the afternoon of Tuesday the 11th of August, with a 3ft WNW swell, but it's a short 6-second period with a gentle cross-onshore wind, making it choppy and poor.
The bottom line: there are no good standouts in this 16-day window. It's a desert for surfers. This kind of blank run is just how it goes here sometimes. The good news is, forecasts can change, so don't give up hope entirely.
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.
