The Lowdown

Alright folks, Rusty here. Let’s be straight with you – this stretch has all the surf appeal of a flat tire. We are looking at a tough 16-day block with barely a ripple on the menu. The first real sniff of a wave doesn’t even show up until Monday the 24th, but it’s messy and blown out, so we’re essentially looking at a dead run from now until the middle of the second week. There will be a big gap of several days straight with absolutely zero surfable recommendations, so don't hold your breath.

Monday the 24th kicks things off with a pulse of stormy, onshore energy at Troia. The swell comes in at 8 ft from the WSW but with a short, gutless period of 8 seconds. The wind is howling from the SW at 19 mph, direct on, and the water feels a touch warmer than usual for this time of year. That combined energy reading of (807) tells you there’s power in the water, but it’s all wind-driven chaos. This is ugly, sloppy surf – more of a kite-surfing setup than a paddle session. Conditions stay poor into the afternoon.

After Monday, we drop off a cliff. The rest of the week and all of the following week show nothing but tiny, weak swell – we’re talking 0.3 ft to 0.7 ft high period leftovers from the SSW. That period stretches out past 15 seconds, which is very long, but with no height it’s just a slow, clean ocean with no push. Winds are offshore or clean from the north, so the water looks pretty, but there’s no wave to ride.

There is a brief, tiny pulse on Sunday the 6th of September with a 1 ft groundswell from the W. The combined energy climbs to a measly (53) in the morning. It’s clean and cross-off, but you’d need a fin to stand on it. Nothing here is worth a second look.

Honestly, this is a write-off. For an area with inconsistent surf, a blank run like this isn't totally abnormal, but it stings. Keep the boards in the car, but don’t hold your breath. Forecasts change, but this one’s looking bleak.

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.
