Alright folks, Rusty here. Let's have a look at what’s on the cards for Castelejo over the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s a tough stretch. We’re looking at a long, frustrating run of poor conditions. From Monday the 6th of July right through to Saturday the 11th, it’s pretty much a write-off. The wind is all over the shop, mostly onshore or cross-onshore, and the swell is tiny and weak. Don’t even bother looking at it until the end of the week.
We finally get a little glimmer on the morning of Sunday the 12th. The wind goes glassy – dead calm – and that makes all the difference. We’ve got a 3 ft swell rolling in from the WNW with a clean 10-second period. The energy is moderate (193), which is the best we’ve seen so far. You’ll find Castelejo smooth and clean early, but it won't last. The sea breeze kicks in by the afternoon with a cross-onshore wind, chopping it right up. Sunday morning is the only real chance for a fun, grovelly session. Water temp is about 69°, which is totally normal for this time of year.
After that little window, it gets messy again. Monday the 13th is onshore and ordinary, and from there we slip back into a pattern of moderate to strong northwest winds. The swell starts to build from the 18th of July, with heights reaching 5 ft and then 6 ft by the 20th, but it’s all coming from the NNW with a short, weak period of 7 to 8 seconds. The energy numbers get big – up to 574 on Monday the 20th – but with that cross-onshore gale, it’s going to be a messy, blown-out mess. At those sizes and those winds, it’s not for the beginners. Honestly, at that point, the setup looks more interesting for kite surfing than paddle surfing, because the conditions are strong, lumpy, and hard to handle.
So, to sum it up: save your energy for a very early paddle on Sunday the 12th of July. That’s the one standout, and it’s a short-lived one. After that, it’s a waiting game for a clean day that just isn’t in the forecast.
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.
