The Lowdown

Right now we’re looking at a pretty flat run in the Troia area over the next 16 days. There’s no real surf to get excited about – the sort of period where you’d be better off checking your gear, going for a paddle, or just kicking back. Even the best of it is tiny and inconsistent, so expectations need to be managed. For this time of year in the region, a quiet spell like this isn’t all that unusual, but forecasts can always shift with a bit of luck.

Taking it from Tuesday the 11th, we start with nothing really worth chasing. Tuesday the 11th kicks off with waves around 3 ft from the west-northwest, but with a period of just 4 seconds – that’s windswell, short and weak, combined energy a paltry 17. On top of that, the wind is WSW at 6 mph blowing onshore, making a messy scene. Definitely a day to sit out.

Wednesday the 12th is flat through the morning, and by the afternoon there’s only 2 ft from the west-northwest with a 3-second period (energy at 7), plus a WSW breeze of 9 mph putting it onshore again. Not a chance.

From Thursday 13th right through to Wednesday the 25th of August, it’s consistently tiny – swell heights bouncing between 0.3 ft to 0.7 ft, with periods mostly around 12 to 17 seconds. Those longer intervals suggest some distant groundswell trying to creep in, but there’s just no size to work with. The combined energy barely climbs into double digits, topping out at 27 on Thursday the 20th in the morning. Winds are mostly offshore or cross-offshore through many of the mornings, which would be clean if there were any waves, but there aren’t. A couple of mornings – like Sunday the 16th and Monday the 17th – even go glassy (wind 0 to 3 mph), which would be perfect if there was an ounce of swell.

There aren’t any standout days here. The closest to something rideable would be the mornings when there’s clean conditions and a tiny 0.7 ft pulse, like around Thursday the 20th or Friday the 21st, but honestly, it just won’t break properly for surfing. The water temp, where noted, sits around 75°F – that’s much warmer than normal for the time of year, about 6° above the long-term average, so if you’re just floating around, it’s pleasant enough.

Bottom line: no real surf to chase for the next two weeks. Check back in a while; these flat spells don’t usually last forever.

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.
