The Lowdown

Alright folks, Rusty here. We’re taking a good, hard look at the next 16 days for the Troia area, and I've gotta be straight with you – it's a tough one. We’ve got a long stretch of flatness or just plain poor conditions ahead, so don't go getting your hopes up too early.

The first proper chance at anything ridable doesn't show up until Friday, July 17th, but even then it's a struggle. We kick off the outlook with a patch of almost nothing. Thursday the 15th has a tiny 0.3 ft southwest swell with a 15-second period, but a cross-on breeze at 12 mph ruins it completely. The combined energy is a measly 13, so there's just nothing there for a surfer.

From July 15th right through to July 26th, it's a brutal run. The only slight glimmer is on Friday morning, July 17th. Troia gets a tiny 1 ft northwesterly swell, period a short 5 seconds, and while the wind is cross-off at 6 mph, the combined energy is only 9. That's a long paddle for a tiny, weak wave. The rest of that week and into the next is a mix of flat spells, tiny bumps, and onshore chop. There’s a period from the afternoon of July 18th through to July 26th where we see a few 2 ft to 3 ft waves, but they're all short period (3 to 6 seconds) and the wind is all over the shop – cross-on, cross-shore, and moderate to fresh breezes. The energy on July 25th afternoon hits 52 with a 3 ft northwest swell, but the cross-shore wind at 15 mph will chop it up.

Then, on Sunday, July 26th, things get interesting, but it's a mixed bag. The morning is clean with a cross-off wind from the NNW at 12 mph, but the swell is a pathetic 0.3 ft from the south at 11 seconds. The afternoon, however, is the standout of the entire forecast. A 4 ft northwest swell with a 6-second period and a clean, cross-off NNW wind at 19 mph. The combined energy is 73, which is still weak, but it's the most we've seen. For a beginner spot like Troia, this is about as good as it’s going to get and it's the only "best on offer". The water temperature is 75°, which is a massive 7° warmer than normal for this time of year – that's very unusual and will feel like a bath. Remember, this is a long-range call, so it’s promising but could shift.

After that, Monday July 27th gives us clean morning winds again, but it drops right back to a 0.3 ft south swell with a long 14-second period. The energy is just 4. Long-period swells like that are typically better for points and reefs, but at a beach break like Troia, they often break too straight. The rest of the run into the end of July is more of the same: flat or tiny, weak swells.

Honestly, folks, this stretch is a write-off for proper surfing. The setup is more interesting for a kite surfer than a paddle surfer on most days. If you're desperate for a splash, the afternoon of July 26th offers the most size with clean conditions, but don't expect much.

Stay patient, keep watching the charts.

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.
