Right, grab a coffee, let's see what's brewing around Castelejo. It's a beach and reef setup here, real consistent spot, exposed to the NW. Honestly, for the next couple of weeks, it's looking like a bit of a patience game. The water's sitting at 68°F, which is pretty much bang on average for this time of year, so no surprises there.
The first half of the outlook is a tough read. From Tuesday the 7th right through to Monday the 20th of July, there's hardly a whisper of decent surf. We're looking at a long, dry spell with nothing but wind-battered, messy conditions. The wind is mostly onshore or cross-onshore, blowing between 12 and 22 mph, just ruining any chance of a clean face. Swell heights are tiny, mostly below 3ft, and the wave energy is weak, sitting below 100 (e.g., 35 to 84). It's just poor surf, day after day. You'd be better off checking the kiteboarders, honestly.
Around Sunday the 12th there's a brief flicker of moderate energy (181), but it's still straight onshore wind, so don't get your hopes up.
Now, we finally get a glimmer of something on Monday the 20th of July. The morning waves are starting to show a bit of life at 4ft from the NNW, with a gentle breeze keeping it onshore but lighter. The energy is picking up into the low triple digits (104). By the afternoon, we’re seeing 5ft from the NW, but that's a moderate breeze onshore, making it messy.
The real standout, if it firms up, is looking like Wednesday the 22nd of July. This is the one to circle. We’ve got a 6ft swell from the NNW in the morning with barely a breath of wind from the WSW at just 3 mph. It’s a light cross-onshore breeze, really just a slight air, and the energy is strong at 406. Then the afternoon kicks in with a 7ft NNW groundswell and a light cross-offshore breeze from the SSW at 9 mph. The forecast is calling it clean with a massive 587 energy. That’s proper juice. For a spot like Castelejo, a long period groundswell from the NNW is going to wrap in nicely, offering some real shape. Just be aware, at 7ft, that's expert territory and crowds are possible here. This is the best on offer, but it's over a week away, so keep an eye on it.
For the rest of the second week, it's more of the same old story: onshore winds and mixed up, poor conditions dominate until that late blip.

Information about the Castelejo Surf forecast
The above surf forecast table for Castelejo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Castelejo can be found by selecting the local surf guide option on the grey menu. Our Castelejo 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 (Castelejo) 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 Castelejo 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.
Castelejo is 25 km (16 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.
