Alright, let’s break down what we’re dealing with at Castelejo.
It’s a beach and reef spot, wide open to the north-west, and the first week is a grind – a long, empty stretch with nothing worth getting wet for. From Friday the 3rd right through the end of that first week, the surf is poor. Tiny, weak swell and the wind keeps it messy – cross-off or straight onshore. You’d be better off staying home.
The only real bright spot, and I mean the only one that’s worth talking about, is Friday morning, July 17th. It’s clean with light offshore wind from the west-northwest. The swell is small, about 3ft, coming from the WNW with a solid 11-second period, so it’s got some shape and push. The energy is moderate (319). For a place that’s been flat and blown out, this is a rare pocket of calm. It’s good for everyone, from beginners to the old salts. Just remember, it’s more than a week out, so take it with a grain of optimism.
After that, the wind goes bad again. By Saturday the 18th, the swell jumps to a messy 7-8ft with a short period (632 energy) and cross-onshore wind. That’s big, ugly, and choppy – more of a kite day than a surf day. For the experts, there will be power, but it won’t be pretty.
So, a long dry spell, then one sweet morning. That Friday the 17th is your only real window.

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.
