Castelejo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s cooking for Castelejo over the next couple of weeks.

Right off the bat, the first few days are a write-off. We’ve got a strong NNW wind blowing cross-onshore through Tuesday and Wednesday the 16th, creating messy, lumpy conditions. The swell is there, bumping up to 8ft to 8ft with moderate energy (717 to 1087), but the wind is just ruining it. Thursday the 17th stays poor with more cross-onshore wind and a big, chunky 8ft swell (energy of 1275). The whole first half of this week is a washout for a decent paddle. This heavy onshore wind and messy surf would be more interesting for the kite crew than us.

Things start to shift on Friday the 18th. The afternoon sees a drop in wind and the swell backs off to 6ft (energy 550), but it’s still onshore and only marginal. That leads us into the first real standout.

Saturday, September 19th, is the pick of the entire forecast. The morning is where it's at. A clean 7ft NW groundswell rolls in with a very long period of 14 seconds, and the wind goes light offshore from the SE at 6 mph. The energy is pumping at 2563, which is very strong. This is prime conditions for experienced surfers. The long period will make for powerful, well-shaped lines, but at a beach and reef setup like Castelejo, it might wall up a bit on the beach sections—find a reef or a peak, and you’re in for a treat. The water is sitting at 66°, which is a massive 5° colder than usual for this time of year, so definitely bring a thick suit. Expect some company too; the crowds are listed as "sometimes," so that Saturday morning session will be busy.

Sunday the 20th cleans up further with offshore winds again from the SE in the afternoon, but the swell drops to 5ft (energy around 500). It’s clean and surfable, but nothing like Saturday’s power. Monday the 21st is smaller again, with a 4ft (energy 316) and clean cross-off winds, but it’s only marginal.

Looking into the second week, we get a bit of a reset. The standout here is Wednesday, September 23rd. The afternoon session is magic: glassy conditions with a light ENE breeze, a 5ft NW groundswell rolling in at 14 seconds (energy 815), and the water will still be cold. The morning of the 23rd is also very good with a 3ft WNW swell at 15 seconds (energy 569) and clean cross-off winds. This is a great day for a long, cruisy session.

After that, we have a solid run of clean, smaller surf from the 24th through to the 28th. Expect clean 4ft to 5ft NW swells with light to moderate offshore or cross-off winds, mostly in the mornings. The combined energy sits in the moderate range (200 to 685). It’s not going to blow your mind, but for consistency and clean conditions, you could surf every morning. Monday the 28th afternoon is worth a mention with a 5ft NW groundswell (12s period) and very good surf conditions (energy 684) under a light cross-off breeze.

The final days of the month, the 29th and 30th, look like they turn poor again as the wind swings back onshore and picks up. Get it while it’s good.

Rusty.
