The Lowdown
Alright, grab a coffee and sit down, 'cause I’ve had a proper look at the charts for Luz, and I’ve got the full rundown for you. Honestly, for the first week, it’s pretty grim. The swell is tiny to non-existent for days on end, with heights barely scraping 0.3 ft. It’s a classic waiting game. The water's sitting at around 67°, which is a full 4° colder than it should be for this time of year, so you’ll want that thick steamer.
Let’s get into it. The first real glimmer of hope doesn’t show up until Sunday 20 September. We finally see some size bump up to 7 ft from the ESE, but it’s got a short period of 8 seconds, and the wind is a messy cross-shore. The combined energy is moderate (1088), but the conditions are marginal. It’s not the best.
The week after gets a bit more interesting. Monday 22 September morning is a standout. The swell holds at 7 ft from the ESE (8 sec), and with a clean cross-offshore breeze and that light air, it’s going to be clean. Combined energy is strong (824). It’s a proper point break here, so that shorter period should still wrap in nicely, and it’s not too big for the experienced intermediate crew.
Then, later in the week, we’ve got a real wild card on Saturday 26 September morning. A solid 5 ft groundswell from the west with a *very* long 16-second period rolls in. The wind is a glassy offshore from the NNW. The energy reading is off the charts (1363). This is the stuff for the crew who know their line-ups. That long period will pulse through and make for some proper, lined-up walls at this point break. It’s a Saturday, so expect a few others out, but for the experienced surfer, this is the session to aim for.
After that, the swell fades fast into the end of the month, dropping back to ankle-biters and poor conditions.
So, to wrap it up: the first half of the run is a write-off. Tuesday 22 September morning is your best bet for solid, clean, intermediate-friendly waves. If you’ve got the skill and patience, the Saturday 26 September morning is the one to circle on the calendar, but it’s a specialist session for the big-wave chargers.

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.
