Table - best surf conditions forecast for The Reef over the next 16 days.
Alright, Rusty here. Let's have a look at what's on the menu for The Reef over the next couple of weeks.
Honestly, it's a bit of a rough patch ahead. We're looking at a solid 10-day stretch, from Friday the 10th right through to Sunday the 20th, where the surf is just not worth paddling out for. The swell is tiny, the wind is a mess, and the conditions are choppy and blown out. It's a real bummer.
The first real glimmer of hope comes on Monday the 21st of July. The morning shows potential with a 5 ft swell from the NNW, and the wind is light and variable, swinging from the south at just 3 mph. It's a glassy start, but the wave comment says it's "marginal," so it's not a guaranteed winner. The combined energy is a moderate 378. The water temperature is around 67°, which is about average for the time of year.
Things pick up a bit later in the week. On Thursday the 24th of July, the swell starts to build. Friday the 25th of July is the standout. The Reef is exposed to the NW, and we're seeing a 7 ft NW swell with a short period of 7 seconds and a combined energy of 421 (strong). That's a powerful amount of water moving. But—and it's a big but—the wind is howling from the NNW at 16 mph, making it a cross-onshore mess. The wave comment is "poor surf conditions." This is a classic case of the reef being too blown out for a clean ride. This setup honestly looks more interesting for kite surfing than paddle surfing. It's expert-only territory at that size anyway, especially with the messy winds.
So, if you're desperate for a paddle, the morning of Monday the 21st is your best, most optimistic bet, but keep your expectations low. The bigger surf later in the second week is just too wind-affected to be any good.
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.
