The Lowdown

G’day, I’m Rusty, and I’ve gotta be straight with you: Troia is looking like a ghost town for surf over the next 16 days. There’s just nothing on offer that’s worth paddling out for. The forecast shows a long stretch of flat days, and when there is a tiny bump, it’s barely a ripple. It’s the kind of run that’s pretty normal for this area when conditions just don’t line up—there’s no swell energy, and what little shows up comes from the wrong direction with no consistency. Don’t hold your breath; forecasts can change, but right now, it’s a write-off.

Starting from September 7th, Monday morning, it’s dead flat with zero combined swell energy (0), and a cross-offshore wind from the N at 9 mph, but you’re staring at glass with no waves. That sets the tone. Tuesday the 8th brings a tiny pulse—3 ft from the NW with a short period of 6 seconds and weak combined energy of just 44—but it’s rated as poor surf conditions. The cross-offshore wind from the NNW at 9 mph keeps the surface clean, but the swell is too small and weak to do anything with. Wednesday the 9th is more of the same: 3 ft from the NW, period of 5 seconds, combined energy of 34, and though the morning stays clean with a 12 mph cross-off, it’s still rubbish.

By Thursday the 10th, the swell drops to 0.7–1.0 ft from the W with a period of 8 seconds and energy around 6–10, but cross-onshore winds blow it out in the afternoon. Friday the 11th and Saturday the 12th are even worse—swell down to 0.3–0.7 ft, with glassy conditions on Saturday morning but no power. Then from Sunday the 13th through to Tuesday the 22nd, it’s almost entirely flat or only showing 0.3 ft of weak, long-period swell from the S (periods of 11–16 seconds), with combined energy values barely reaching 6. That’s not surf—that’s a lake. A few mornings have glass or light offshore winds, but with no wave height, it’s just a pretty piece of water.

In short, there is not a single standout session here. The best you could hope for is maybe a tiny clean wave on Tuesday the 8th morning, but even then, it’s a beginner-level dribble—not worth getting wet for. If you’re itching for something, you might be better off with a kite on those rare days with a bit of wind, but honestly, save your energy.

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.
