The Lowdown
How's it going, surfers? Rusty here, checking in for Castelejo.
Honestly, you're looking at a pretty long stretch of nothing for the next week and a bit. From Friday the 7th all the way to Saturday the 15th of August, it’s a real bummer: messy chop, onshore and cross-onshore winds, and tiny waves that just won't shape up. The water sits a touch colder than normal at about 68°, nothing too wild. For nearly 9 days, there’s just nothing to get excited about. It’s a real test of patience.
The one and only highlight shows up on the morning of Sunday the 16th of August. A glassy morning with a light offshore breeze from the ENE at just 3 mph. You’ll get a 4ft NW swell, with a solid moderate wave energy of 205. That glassy surface is going to clean everything right up. It’s a beach and reef spot that’s very consistent, and the NW direction hits its peak. Since it’s a beginner-friendly break, that 4ft swell will be fun and manageable, and with the lull in crowds it should be a real treat. The rest of that day and into the next week just goes back to being poor, but that one morning session is your only real window.
A long, quiet run from the 7th through to the 15th, and then one golden morning.
Rusty, signing off.

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.
