Table - best surf conditions forecast for The Reef over the next 16 days.
Hey, Rusty here. Gotta be straight with you—this outlook is a rough read. The next two weeks are a real test of patience, with almost nothing worth paddling out for until the middle of next week.
The opening days? Forget it. From Tuesday the 7th right through the weekend of the 12th, it’s flat and messy. No juice, no shape, just wind chop.
Your one and only shot comes Monday morning, July 13th at The Reef. This is a classic reef setup, wide open to the NW. The morning goes glassy, which is huge for keeping the surface silky smooth. Swell is a tiny 3ft from the NNW, but with that still air and a 8-second period, it’ll be rideable and fun on the right board. The combined wave energy is moderate (110), so it’s not a powerhouse, but it’s clean. Water temp is about 68°, which is par for the course. Expect it to be busy, because this is pretty much the only game in town.
That’s it. From Tuesday the 14th onward, the wind picks right back up, and the swell fades hard. The second week is a total dud. It’s one of those stretches, but you know how it goes—things can change.
Rusty.

Information about the The Reef Surf forecast
The above surf forecast table for The Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at The Reef can be found by selecting the local surf guide option on the grey menu. Our The Reef 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 (The Reef) 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 The Reef 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.
The Reef is 15 km (9 miles) from the city of Sintra. If you plan a holiday in Ericeira, look for hotels and other accommodation in Sintra. Sintra has rooms for a wide range of budgets as well as car hire and transport links.
