The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer down at Praia da Vieira.
Honestly, it’s a pretty flat and frustrating run for the next couple of weeks. We’ve got a long stretch of poor surf conditions ahead. The first sniff of anything rideable shows up on the morning of Tuesday, 21 July. We’re looking at small, clean waves with a glassy surface. The swell is from the NNW at 2 ft, with a period of 8 seconds, and the combined wave energy is weak (76). The water is sitting at 69°, which is a touch warmer than normal for this time of year. It’s surfable, but it’s very ordinary, and you’ll be fighting for scraps.
From Tuesday afternoon all the way through to the end of July, it’s a grim picture. The wind picks up onshore or cross-onshore, the swell stays tiny or gets messy. The morning of Saturday, 25 July, we see a jump in height to 5 ft from the WNW, but the wind is a cross-onshore mess and the combined energy is moderate (245). It’s not worth paddling out for. The same goes for Sunday, 26 July, with 6 ft from the NNW in the morning and a fresh cross-onshore wind making it lumpy. That’s not a surf, it’s a washing machine. Even with the energy up (379), it’s poor.
We get a slight break on the morning of Monday, 27 July, with 5 ft NNW swell and a light cross-onshore. The conditions are marginal, but it’s the first time we see a score of 1, so it’s at least worth a look. The energy is moderate (259). Still, the wind is a problem.
The real standout, and the only one I’d actually get excited about, is the morning of Thursday, 30 July. The wind goes glassy, and we get a clean, small 1 ft swell from the WNW with a longer period of 10 seconds. The energy is low (65), but the conditions will be smooth. It’s surfable, but very ordinary. For the size, it’s one for the log or a longboard.
After that, we’re back into the poor run. The morning of Tuesday, 4 August, shows a 4 ft from the NNW with a light cross-onshore and moderate energy (207). It’s marginal, but nothing to shout about. The rest of the forecast is a dead loss.
So, to sum it up: the best bet is the morning of Thursday, 30 July, for clean but tiny waves. Everything else is a fight against the wind or just flat. If you’re desperate, the morning of 21 July or 27 July might give you a few, but don’t expect much.
Rusty.

Information about the Praia da Vieira Surf forecast
The above surf forecast table for Praia da Vieira provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Praia da Vieira can be found by selecting the local surf guide option on the grey menu. Our Praia da Vieira 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 (Praia da Vieira) 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 Praia da Vieira 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.
Praia da Vieira is 14 km (9 miles) from Marinha Grande. If you plan a holiday in Beira, look for hotels and other accommodation in Marinha Grande. Marinha Grande has rooms for a wide range of budgets as well as car hire and transport links.
