Alright, Rusty here. Let's have a look at what we've got.
First up, no beating around the bush: the next two weeks are a real struggle. We've got a little swell trickling in, but the quality just isn't there for a proper surf. The first few days are poor. From Monday, July 6th through to the weekend of July 13th, the waves are small and weak. The combined swell energy is mostly below 100 (28 to 51), so it's barely a ripple. We're talking 0.7 ft to maybe 2 ft on the better days. Even though the wind is often offshore or cross-off, it's just not enough push to make anything worthwhile. For a spot that's "very sheltered" and inconsistent, this is a tough run.
The only real flicker of hope comes late in the second week. Starting Sunday, July 19th, the swell finally starts to show some muscle, pushing up to 5 ft to 6 ft from the NNW, with combined energy climbing into the 300-400 range. The issue? That's right when the wind really cranks up—strong breezes and near gale-force. On the 19th afternoon we get a strong offshore at 28 mph, but that's a case of "looks great in the car park, terrifying in the water." The wave comment says it straight: "strong offshore and clean but hard to paddle into." This is more for the kite crew than a longboard session.
By Tuesday, July 21st, the swell is up to 7 ft from the NNW with energy hitting 545—that's a solid wall of water. But with a short period of just 8 seconds and that wind screaming offshore, it's messy, powerful, and only for the experts. Even then, it's going to be a battle to get out back.
So the honest truth? There is no standout day for a relaxed, fun surf in this entire forecast period. Mareta is an inconsistent, sheltered break, and when the swell finally arrives, the conditions are too extreme.
Rusty.

Information about the Mareta Surf forecast
The above surf forecast table for Mareta provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Mareta can be found by selecting the local surf guide option on the grey menu. Our Mareta 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 (Mareta) 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 Mareta 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.
Mareta is 26 km (16 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.
