The Lowdown
Alright folks, Rusty here. I've been staring at the charts for the home break, and I gotta be straight with you—it's a lean stretch ahead. For the first twelve days, from the 6th of August right through to the 17th, it's a write-off. We're talking a solid week and a half of poor surf conditions. The wind just won't play nice, mostly a cross-onshore mess, and the swell is tiny and weak. There's barely enough energy to move the seaweed, let alone a surfer. The combined energy values are all in the double digits or low triple digits, struggling to get past 200, which tells you it's weak sauce. It's a tough run, but it's just how it goes sometimes.
Now, hang in there, because we finally get a glimmer of hope. The first real standout arrives on Tuesday the 18th of August. Luz (reef/jetty) is the only break in the game here, and it finally shows some life. We're looking at a cleaner morning session. The wind swings around to a light cross-offshore from the NE at 6 mph, which is a massive improvement. It'll be clean. The swell pushes up to 4 ft from the WNW, with a period of 8 seconds. The combined energy jumps to 251 (moderate wave energy). It's not a giant day, but after the drought, a clean 4 ft with some push is a welcome sight.
Then, Wednesday the 19th of August morning also looks promising. The wind goes completely glassy, calm as a lake. The swell drops a touch to 3 ft from the NW, but that glassy surface is major. The energy is moderate at 140. It's a smaller, cleaner morning session for the crew who can get out. The water temp is about average for the time of year, so nothing too wild.
Beyond that, it starts to fade again. The 20th has a glassy morning but the swell is tiny at 2 ft, and the 21st is back to a cross-on breeze. So, your best bet is to mark your calendar for the 18th and 19th of August. Go get a slice of that clean, glassy action before the next lull sets in.
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 3 km (2 miles) from Matosinhos. If you plan a holiday in Douro and Minho, look for hotels and other accommodation in Matosinhos. Matosinhos has rooms for a wide range of budgets as well as car hire and transport links.
