Castelejo Surf Forecast and Surf Report

Alright, let me tell you how it’s looking at Castelejo over the next couple of weeks. Honestly, it’s a tough run ahead. There’s no real standout, but I’ll give it to you straight.

The window kicks off on Monday the 24th of August with a fresh 7ft west swell rolling in, but it’s coming with a cross-onshore wind from the WSW at 12 mph, making things choppy and poor. The water’s sitting at 68°, which is a bit colder than we’d expect for this time of year. Not the start we want.

Tuesday the 25th morning is your best chance, and it stands out as the best on offer. We’ve got a 5ft swell from the WNW, with glassy conditions—dead calm, zero wind. That’s clean. The period is 8 seconds (238 energy), so it won’t hold much punch but it’ll be rideable and you’ll have some fun. But come Tuesday afternoon, the cross-onshore returns, dropping the quality.

From there, it’s a slog. Wednesday the 26th through Sunday the 6th of September is mostly poor with constant cross-onshore winds, bumpy and lumpy surf, mostly in the 2ft to 6ft range. Wind speeds often hit 16 to 25 mph, so it’s messy. On Thursday the 27th, it’s 19 mph from the west – that’s fresh cross-onshore and lumpy. Not worth paddling out unless you’re into a beating.

Friday the 28th shows 8ft from the WNW with an 11-second period, but it’s still cross-onshore and the waves are fat and lumpy. The energy’s moderate (1545), but wind ruins it. Saturday the 29th and Sunday the 30th are more of the same – fresh breeze and lumpy.

By the end of the first week, Monday the 31st has 25 mph NNW winds and that’s just yuck. Into September, the first few days bring strong cross-onshore winds with 6ft to 7ft swells but the wind’s up again.

There is a little flicker on Friday the 4th and Saturday the 5th of September – the swell drops to 6ft to 6ft from the NW with gentler winds, but direction is still cross or cross-on, so it only manages marginal surf. Sunday the 6th shows a 3ft swell with a 12-second period but again onshore wind.

Further out, the 7th and 8th of September have a massive long-period groundswell from the WNW – 3ft at 23 seconds Monday morning (1487 energy) and 5ft at 20 seconds Monday afternoon (2670 energy), then Tuesday the 8th brings 8ft at 14 seconds (2405 energy). The sea’s carrying some serious power, but the wind’s still cross-onshore at 19 mph. For a beach and reef setup like this, those long-period groundswells often break too straight and the wind will keep it messy. Might be better to leave the paddle board at home unless you’re a pro – 8ft is getting big and it’s for experts only.

Overall, the one standout is Tuesday morning the 25th of August – Castelejo at 5ft from the WNW, glassy calm, clean. That’s your window. Everything else is a fight against the wind. It’s consistent, but the quality just isn’t there. Crowds? Probably manageable since it’s rarely good enough to draw a pack.
