The Lowdown

Alright folks, Rusty here. Let's be straight with you – this forecast for Troia is a tough one to write. The next couple of weeks look pretty flat and grim for most of us. The guidance gives it a 1/5 rating with only inconsistent surf, and that’s being generous. We're looking at a long stretch with barely a ripple, so if you're after waves, you might want to find another project for the next week or so.

The early part of the period, from Friday the 11th through the weekend, is a total write-off. We're talking ankle-snappers at best, with swell heights around 0.3ft at best. The energy is weak, with values in the low single digits. The water temp is currently 72°, which is a touch warmer than normal for this time of year, so at least the water will be nice for a swim.

There’s a slight uptick in energy on Tuesday the 15th afternoon when the wind picks up from the NW at 15 mph, bumping the swell to 3ft, but it’s short-period, cross-shore, and lumpy. That’s not surfing, that’s a washing machine. The combined energy does hit 40, which is a bit more, but it’s still weak and pretty much unsurfable. This isn't looking like a paddling day; more like a session for the kite crew if you're into that sort of thing.

We then hit a long, flat gap for several days, with nothing on offer from the 16th through the 23rd. There are days with tiny 0.3ft blips and some clean, offshore winds, but with that lack of size and energy, it's still not worth suiting up. The energy levels barely register, sitting in the low single digits most of the time.

Things start to look slightly more hopeful as we move towards the end of the period. Around Wednesday the 23rd and Thursday the 24th, we see some 0.7ft to 1ft swells from the SSW with slightly more energy and clean cross-off winds, but it’s still tiny. The most promising window is the 24th, with a 0.3ft swell coming from the S with a period of 15 seconds. That's a long-period groundswell, but the size just isn't there. It will be clean under NNW winds, but it's still just not enough to get excited about.

This is a classic blank run for the area. With a break that’s this inconsistent and a forecast this poor, it’s not a surprise. Don’t bank on anything from this outlook. The forecasts can always change for the better, but as it stands, there are no standout days on offer. For Troia, we just have to be patient and wait for the next proper pulse of swell.

The 24th looks like the pick of a bad bunch, but it's a long way off and still very marginal. I'd keep an eye on it, but don't hold your breath. The energy in that one is only 7, which is weak, but it has a nice long period. It's promising but less certain, and right now it's about as good as it gets.

Keep the board dusty, folks.

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.
