The Lowdown

Well, folks, it’s Rusty here, and I gotta be straight with you—this is one of those rare stretches where Troia is just not playing ball. We’ve got a solid 16-day window ahead, and honestly, there’s hardly a ripple worth paddling for. The whole outlook is a big ol’ blank, so don’t bother waxing up just yet. When an area goes this quiet, it’s not unusual—Troia can be a fickle beast, and we’re in the thick of a flat spell.

Let’s start from the beginning. Monday the 27th of July kicks off with a weak 2ft swell from the WNW, but the period is a shocking 3 seconds—that’s wind chop, not surf. The wind is onshore at 9 mph, and the combined energy is a paltry 11 (weak). Poor conditions all around. That sets the tone for the whole run.

Tuesday the 28th morning is glassy, but there’s no swell at all—zero energy. The afternoon brings a tiny 0.3ft WNW swell with a 12-second period, but it’s cross-onshore at 12 mph and choppy. Not worth a second look.

Wednesday the 29th is another glassy morning with no swell, and the afternoon is a repeat of Monday: 2ft, 4-second period, cross-onshore wind. Energy is a weak 8. The rest of the week and into early August is a parade of tiny, short-period bumps or flat spells. The combined energy rarely breaks double digits, and when it does, like on Friday the 31st afternoon with 13, it’s still weak and accompanied by a 12-second period swell of only 0.7ft—barely a ripple.

The one faint glimmer comes on Wednesday the 5th of August afternoon. That’s the only time we see a swell height over 4ft—4ft from the WNW—with a combined energy of 73 (still weak to moderate). But the period is a short 5 seconds, and the wind is a fresh 19 mph from the NW, creating a lumpy cross-chop. It’s messy, not clean, and definitely not for beginners at that size. Not worth getting excited about.

Thursday the 6th morning has a 3ft NW swell, 5-second period, and 54 energy, but the wind is cross-offshore at 12 mph, so it’s clean. Still, the short period means the waves are weak and crumbly. Not a standout.

After that, from the 7th of August onward, it’s all flat or tiny, with no swell worth mentioning. The afternoons get hammered by fresh breezes around 19-22 mph, but there’s no surf to mess up.

Water temperature on the 27th is 74°F, which is 5°F above the long-term average—much warmer than normal for this time of year. That’s very unusual.

So, here’s the bottom line: If you’re a surfer, this is a time to hang the board up and maybe check out the kitesurfing potential. The beach setup with those cross-shore winds and occasional bumpy conditions looks more interesting for kite than paddle surfing. There are no good surf options in this 16-day window. It’s a rare blank run, but it happens here. Forecasts can change, so don’t lose hope entirely.

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.
