The Lowdown
Alright, Rusty here, let’s have a look at what’s cookin’ for Castelejo over the next couple of weeks.
Honestly, mate, the outlook is a bit of a tough one. The whole 16-day stretch is a write-off for decent surf. There’s not a single solid recommendation in the window. We’ve got swell, yeah, but it’s blown out by persistent cross-onshore winds from the north and north-northwest. The water is a chilly 66°, which is a whopping 4° colder than usual for this time of year – that’s seriously unusual and you’ll feel it.
For the first week, from July 28th right through to August 5th, it’s a constant story of onshore or cross-onshore winds, mostly from the NNW, with wave heights struggling between 1 ft and 4 ft. The swell periods are short, mostly under 10 seconds, and the energy is weak to moderate. The surf is just poor – choppy, lumpy, and messy. Not worth paddling out.
Then we hit August 6th through the 12th, and the swell actually picks up. The combined energy jumps into the hundreds and even thousands, with wave heights reaching 5 ft to 8 ft. On the 11th and 12th, we see a nice long-period groundswell from the NW, with periods over 12 seconds and big energy. But the wind is still hammering it. Strong breezes from the north and NNW keep it cross-onshore and messy. That 8 ft swell on the 11th afternoon is for experts only, but the wind will ruin it anyway. For a beach and reef setup like Castelejo, it’s actually looking more interesting for the kite surfers than for paddle surfing.
So, bottom line: there’s nothing to get excited about here. The whole 16 days is a blank run. It’s a bit of a bummer, but it happens. Forecasts can change, but for now, leave the boards at home.

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.
