The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Castelejo over the next couple of weeks.
Honestly, I’ve got to be straight with you – this is a tough one. The forecast is serving up a real flat spell, and it doesn’t look like it’s going to offer much for a paddle surfer. The whole 16-day window is a complete write-off. There’s not a single decent recommendation in there. We’re looking at a solid blank run from start to finish.
The main issue is the wind. For the first ten days, we’re dealing with a persistent moderate to fresh breeze out of the NNW, coming straight onshore or cross-onshore, which is just mangling any small bumps that try to roll in. The swell is weak, with the combined energy mostly sitting in the low to mid 100s, and that’s just not enough to overcome the chop. The water temperature is currently sitting at 66°, which is a notable 4° colder than normal for this time of year.
Even when the swell tries to push a little higher, like on the 6th of August with a 6 ft NNW swell, it’s period is short at 6 seconds and the wind is a fresh 22 mph cross-onshore. That’s lumpy, bumpy, and only really interesting for kite surfers, not for us. The wave energy hits 253 (moderate) but it’s all wind-slop junk.
Towards the 14th of August, we see a bit of a tease: a 3 ft swell from the NNW with a 10-second period, and the energy climbs to 243 (moderate). But again, the wind is onshore, and the score is still zero. It’s just more of the same.
Look, Castelejo is a very consistent beach and reef, so it’s not like it’s a spot that rarely gets waves. This is just a poor run of conditions. The good news is, it tends not to stay this poor for long, and forecasts can change. But for now, keep the board in the car and maybe go for a hike. This is a 16-day flat spell.
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.
