The Lowdown
Alright, let me tell you how things are shaping up for Castelejo. The next couple of weeks are a bit of a mixed bag, with some real gold to be had if you're patient.
Right now, the surf is small and clean. Monday morning, we've got a 4ft NW groundswell pushing in with a 12-second period and a light offshore wind, so the waves are looking tidy. The water is sitting at about average for this time of year. It’s a pretty gentle start, ideal for a beginner or someone just wanting to get wet. Combined energy is moderate (338).
Tuesday and Wednesday are a write-off, I’m afraid. The wind swings onshore and the swell drops, turning the place into a bumpy mess. By Wednesday, that swell jumps to 8ft, but with a 40 km/h cross-onshore, it’s just a washing machine. Not worth paddling out. The energy gets strong (968), but it’s all wasted on bad wind.
The standout window arrives Saturday the 19th and Sunday the 20th. This is the one to circle on your calendar. Saturday morning brings in a solid 7ft NW groundswell with a very long 14-second period. The wind goes offshore from the southeast, bumping the energy up to a strong 1626. The conditions are clean. This is excellent for experienced surfers—the size (over 5ft) means beginners should sit it out, but for anyone with a bit of time in the water, it’s going to be firing. Expect big, lined-up waves at this exposed beach and reef setup. The offshore wind will keep the faces smooth.
Sunday is almost as good, with the swell dropping to 5ft but still a nice 12-second period and clean cross-offshore wind. The energy is moderate (522). It’s a great window for a wider range of surfers, with clean, fun waves.
After that, we get a few more clean days on Monday the 21st and Tuesday the 22nd, with chest-high swell and light winds, but the south-facing wind shifts later in the week will mix things up again. The crowd situation at Castelejo can get busy sometimes, so get in early, especially on those peak days.
Later in the second week, Friday the 25th looks promising with a 5ft to 5ft WNW swell and clean conditions, and Saturday the 26th still has offshore winds, but the swell drops and the winds pick up, making it a bit more of a gamble.
For the absolute best, it’s Saturday the 19th and Sunday the 20th. Don’t miss it.

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.
