Alright folks, Rusty here. Let’s take a hard look at what’s coming up for the swell window.
Right off the bat, I gotta be straight with you – this is a tough stretch. We’re looking at a solid run of poor surf conditions right through the forecast period. For the first several days, the swell is tiny and the wind is a mess, so don’t bother paddling out. There’s a long gap of weak, choppy surf with no real recommendation until things start to change around the 11th of July.
The real story here, and the only true standout, is the swell that builds up for the weekend of the 18th and 19th of July. That’s when we finally see some size. By the morning of Saturday the 18th of July, the combined swell energy jumps right up to strong territory (627) with a 6 ft swell from the NNW. It keeps going into Sunday the 19th with a 7 ft swell from the NW and a combined energy hitting a massive 771. The catch? The wind is onshore or cross-onshore the whole time, which will mess with the surface, and with that size at Castelejo, a beach and reef setup, it’s going to be a handful. If you’re an expert and you don’t mind a bit of chop, that Sunday the 19th could be the best shot for some power, but it’s not clean. Anything over 5 ft here with this wind is no place for beginners.
Water temp is sitting around 68°, which is pretty much average for the time of year, so no wild surprises there.
Look, overall, the 16-day window is mostly a write-off for quality waves. The only potential for any real size comes in that second week. Keep your eyes on the charts, but right now, don’t get your hopes up.
Rusty.

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.
