The Lowdown
Alright folks, Rusty here. Let’s get straight into it. The outlook for Troia over the next 16 days is a tough one. We’ve got a long stretch of almost nothing to ride, so grab a coffee and listen up.
There’s a gap of no worthwhile surf from now until the end of the forecast period. The first few days back on Wednesday 9 September aren’t calling for a paddle. Wednesday morning shows a tiny 2ft NW swell, but with a cross-off NNW breeze at 12 mph, it’s messy and the energy is weak (21). That afternoon, the swell pushes to 5ft NW, but the wind swings cross-shore from the NW at 16 mph, chopping it up. The combined energy is still weak (98). Not worth it. Thursday 10 September and Friday 11 September are flat or near-flat, with clean, glassy mornings but no size. Saturday 12 September and Sunday 13 September are the same story – small, weak, and not breaking. You’ve got a long run of flat days from the 9th through to the 24th, with only tiny pulses of 0.3ft and very low energy all the way. The biggest blip comes on Wednesday 16 September afternoon with a 2ft NW swell showing some life at 18 combined energy, but it’s still poor. The best of the whole window is Thursday 24 September morning. A 0.3ft SW groundswell with a long 16-second period, offshore NNE wind at just 3 mph, and clean conditions. The combined energy is only 13, so don’t expect much push, but the wind will be glassy, and the long period might wrap into the bank. Still, it’s tiny.
Troia is a beginner spot, inconsistent, and crowds are sometimes an issue, but right now there’s nothing to crowd over. The water temperature anomaly is about average for the time of year, so nothing to write home about there. For 16 days, we’re looking at a blank run. This is pretty normal for the area when the swell goes quiet. It’s a real bummer, but forecasts can change. Keep your eyes on the charts.

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.
