The Lowdown
G’day, Rusty here. Look, I’ll level with you – this stretch of coast is going through a real quiet patch. The first week and a half is basically a write-off. From the 17th of August right through to the morning of the 28th of August, there’s barely a ripple worth paddling for. It’s a long, flat gap with no real surf to speak of. We’re talking tiny little slop that never cracks a proper wave face, and the wind is all over the shop. It’s a frustrating run of nothing.
The first real glimmer of hope comes on the morning of Friday the 28th of August at Luz (Portugal). This is the standout of the whole 16-day window, and it’s a bit of a late bloomer. For the first time, we see a pulse of energy. The combined swell energy hits 393 (moderate energy), with a 5 ft swell rolling in from the ESE. The period is a short 8 seconds, so it’s a windswell, not a groundswell, but the conditions are the real story here. The wind is glassy, absolutely flat calm. That means the surface will be clean as a whistle. The water temp is sitting at 67°F, which is 5°F colder than usual for this time of year – that’s a notable chill, so don’t forget a decent spring suit. Luz is a point break, so it handles that direction alright, and because it’s inconsistent, it’s not like it’s going to be packed. For a Friday morning session, you could do a lot worse. That 5 ft is a bit much for beginners, but intermediate surfers will be stoked.
The afternoon of the 28th gets a bit cross-off shore with a WNW breeze, so the quality drops, but it’s still surfable for the keen.
Moving into the 29th of August, Saturday morning offers another 5 ft from the ESE, but the wind is a moderate offshore from the NNW. It’s clean, but the combined energy is down to 230, and the period is still short at 8 seconds. It’s surfable but ordinary, nothing special. The afternoon gets a fresh 35 km/h offshore from the NW, which is a bit too strong to be ideal, and the wave quality suffers. By the 30th of August, Sunday morning, we’re down to 3 ft from the E, with a gentle offshore breeze. It’s rideable, but the energy is only 137 – weak. After that, it fades away again to flatness and tiny dribble right through to the 1st of September.
So, bottom line: the only true stand-out is the Friday morning, 28th of August, at Luz. That’s your window. Mark it in your calendar. The rest of the run is a whole lot of nothing with a couple of ordinary, forgettable sessions tacked on. Stay patient.
Rusty.

Information about the Luz Surf forecast
The above surf forecast table for Luz provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Luz can be found by selecting the local surf guide option on the grey menu. Our Luz 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 (Luz) 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 Luz 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.
Luz is 5 km (3 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.
