The Lowdown
Alright, let’s chew the fat on Castelejo.
It’s a rough patch, mate. The whole 16-day stretch is a write-off for good waves. The water is a lot colder than usual for this time of year—sittin’ at 66°F, which is a solid 4°F off the norm, so you’ll feel that sting.
The main problem is the damn wind. It’s a fresh breeze out of the north or north-northwest most days, blowin’ cross-on or straight onshore. That’s gonna tear up the surface at this beach and reef setup. The swell lingers between 1ft and 5ft, mostly from the west-northwest, but the period is short and the wave energy is weak, often below 200 (57 to 270). It just ain’t got any punch.
From Thursday 30 July all the way through Friday 14 August, every single entry is labeled “poor surf conditions.” There’s no hidden gem. The swell bumps up a bit on Friday 14 August to 5ft, but with a short 6-second period and a strong cross-onshore wind, you’re lookin’ at a lumpy mess. Honestly, that setup looks better for kite surfing than paddling out.
If you’re really itchin’, the best shot is on Monday 04 August morning—a gentle breeze, a 3ft west swell with a 9-second period. But it’s still onshore and weak. Not exactly a day to call in sick for.
Bottom line: leave the boards in the shed for a couple weeks. This spot is usually consistent, so it won’t stay this flat and choppy forever, but right now, there’s nothin’ worth paddlin’ for. Forecasts can flip, so keep watchin’, but don’t get your hopes up.

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.
