Alright, let's break this down for the next couple of weeks at The Reef.

Honestly, looking at the whole 16-day window, it’s a real mixed bag. There’s some decent swell building in the second week, but the wind is going to be a constant issue. This spot is a reef setup, exposed to the northwest, and the best direction is a clean north-west swell. The water temp is sitting right around 67°F, which is pretty much where it should be for this time of year.

The first week-and-a-bit is a write-off for any kind of decent surf. From Saturday the 4th of July right through to the morning of Friday the 17th of July, it’s a long, frustrating stretch of poor conditions. The swell is tiny, mostly under 3ft, and when it does pop a little bit, the wind is a messy cross or cross-on shore from the north-northwest. It’s constantly choppy or lumpy, and you’ll be fighting a bumpy ocean for nothing.

The first real glimmer of hope arrives on Saturday morning, the 18th of July. Now listen, this isn't epic, but it’s the standout of the whole forecast. The wind goes completely glassy, dead calm from the west, and that’s huge. You’ll have a clean, smooth surface on a 3ft swell from the northwest, with an 8-second period. Just be aware, this spot can get crowded, so you’ll have some company.

Then on Sunday morning the 19th of July, there’s a bit more size, pushing 4ft from the northwest. But the wind swings to a light cross-on from the south-southwest. It’s still surfable, and it’s a better wave size, but it won’t have that same perfect, silky finish as the Saturday morning session.

So, my pick is simple: if you can only get out once, make it Saturday morning the 18th of July. It’s the only time in the whole run where the conditions line up for a genuinely clean surf. The Sunday has more push but a bit of wind chop to deal with. The rest of the window is a no-go.

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.
