The Lowdown
Right then, let’s have a look at what we’ve got. This is the 16-day picture for Meia-Praia, and I gotta be straight with you – it’s a pretty flat run. The entire forecast window is filled with poor surf conditions, with wave energy barely registering. There’s a long stretch of tiny, unrideable swell ahead, so don’t be in a rush to grab your board.
Kicking off from Tuesday the 18th of August, we’re looking at a tiny 0.7ft SSW swell with a very long 16-second period. But don’t be fooled by that period; the wave energy is feeble at just 24. It’s also cross-onshore, so it’s going to be bumpy. Wednesday the 19th is much the same, with a 0.7ft swell and a dropping period, and the combined energy is already down to 20. By Wednesday afternoon, the swell collapses to 0.3ft and the period drops right off to 4 seconds – basically nothing.
Thursday the 20th offers a slight tease with a 1.0ft swell in the morning, but from there it’s a long, drawn-out period of tiny waves. From Friday the 21st right through to Wednesday the 27th of August, we see a persistent pattern of offshore winds – fresh to moderate breezes from the NNW and NW, which would keep things clean, but the problem is the swell. The height is stuck at a pathetic 0.3ft, and the combined energy is in the single digits. That’s not surf, that’s a lake. The water temp is about average for the time of year, so no drama there, but there’s just no power.
The only slight change comes around the weekend of the 29th and 30th of August. On Saturday morning the 29th, we get a noticeable bump to 1ft from the ESE, with a combined energy of 15 – still weak but at least it’s something. The winds are light and cross-off, so it’ll be clean. But it’s still tiny. Then on Sunday the 30th, we see a glassy morning with a 0.7ft ESE swell. It’s clean as a whistle, but the wave energy is only 3. You could probably catch a ripple on a longboard if you’re patient, but it’s not exciting.
There’s nothing in this 16-day outlook that stands out as a session worth chasing. For a beginner, the size is safe, but there’s simply no wave to learn on. The setup at Meia-Praia is a beach break that’s fairly exposed, but with no swell and light winds, it’s just not going to break. With the conditions as they are, the consistent offshore wind on those tiny days is more interesting for a kite surfer than a paddle surfer.

Information about the Meia Praia Surf forecast
The above surf forecast table for Meia Praia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Meia Praia can be found by selecting the local surf guide option on the grey menu. Our Meia Praia 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 (Meia Praia) 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 Meia Praia 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.
Meia Praia is 1 km (1 miles) from Lagos. If you plan a holiday in The Algarve, look for hotels and other accommodation in Lagos. Lagos has rooms for a wide range of budgets as well as car hire and transport links.
