The Lowdown
G’day, it’s Rusty here. Let’s be straight with you: the next couple of weeks are looking pretty grim for a proper paddle. The swell is tiny, the energy is mostly weak, and we’ve got a long stretch of nothing worth getting excited about. We’re talking about a real flat spell, so if you’ve got a longboard or a foil, that’s your best bet. For a regular shortboard, you might as well take up golf for the next fortnight.
The first few days, from Friday the 14th through to Sunday the 16th, are almost completely flat. We’re looking at 0.3ft of swell with combined energy sitting down around 3 to 10. There’s a mix of light winds, but it doesn’t matter – there’s nothing to ride. The water temp at this stage is a notable 75°, which is a couple of degrees warmer than usual for mid-August, so if you’re just going for a swim, it’s lovely.
Moving into the middle of next week, Monday the 17th and Tuesday the 18th, we see a slight bump to 0.7ft on Tuesday, but the energy is still pathetic, only reaching 24. The wind is mostly onshore or cross-onshore, and while Monday morning is glassy, there’s just no wave to catch. It’s frustrating, but it is what it is.
There’s a bit of a tease on Saturday the 22nd. The morning shows a pulse to 2ft from the WNW, with a short 5-second period. The energy is still low at 22, and the period is so short it won’t hold any shape. It’s a blip, not a session.
After that, it’s back to tiny dribbles. From the 23rd through the 27th, we’re looking at 0.3ft to 0.7ft at best, with energy mostly in the low single digits or low twenties. The wind is often from the southwest or northwest, sometimes cross-off, but it’s irrelevant because there’s no swell to groom.
Honestly, there are no standouts here. The only spot on the map, Troia, is inconsistent at the best of times, and with this outlook, it’s not breaking at all. The swell direction from the south or southwest is never working with the conditions, and the short periods mean even if there was height, it would just be mush.
The last couple of days, the 28th and 29th, the swell drops out completely, with no wave height recorded at all. The wind gets fresh from the north and northwest, but you’d be better off with a kite than a surfboard.
So, there you have it. A flat, quiet period with a few glassy mornings but no actual surf. If you’re dying to get wet, it’s a swim and a tan, not a surf. Keep the board in the car, but don’t hold your breath. Forecasts can change, but this one looks pretty stubborn.
Catch you next time.

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.
