The Lowdown
Alright, Rusty here again. Let’s break this down for the imperial crew.
Well, I hate to start with bad news, but this forecast is a rough one. For the next week and a half, there’s almost no surf to speak of – just tiny, weak bumps and mostly poor conditions. Water temp is around 71°, which is about normal for this time of year, so that’s something.
The first chance of anything rideable shows up on Tuesday the 15th of September. Tuesday afternoon we get a small 3ft swell from the NW, but it’s got a short period of only 4 seconds. Combined energy of all swells directed here is only 36, so it’s weak. The wind will be a moderate cross-shore, so it’ll be choppy. Not a day to get excited about.
The rest of that week and into the next stays flat and poor. A few glassy mornings, like Thursday the 17th and Saturday the 19th, sound nice, but with only 0.3ft of swell, there’s nothing to ride. Tough times.
The best we can hope for is Friday the 25th of September. Friday morning could see a glassy, clean session with 2ft swell from the WNW and a 5-second period. Combined energy is 16 – still weak, but with glassy conditions it could be okay on a longboard.
Saturday the 26th brings a similar 2ft swell from the WNW, but the wind turns onshore and the energy stays low at 26. Not worth the drive.
After that, Monday the 28th gets windy and lumpy with fresh onshore wind. That kind of setup at a beach break like this is more for the kite surfers than paddle surfers.
So, if you’re itching, Friday the 25th morning is your best shot for clean but tiny waves. Otherwise, it’s a waiting game. Forecasts can change, but for now, it’s looking quiet.
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.
