Castelejo Surf Forecast and Surf Report

Alright, let’s break it down. Rusty here, and for Castelejo, the first half of the forecast is brutal.

Starting Thursday the 27th of August through Wednesday the 2nd of September, it’s all poor. Swell runs from 0.9ft to 7ft, but the wind is cross-on or onshore from the N or NNW, blowing 15 to 25 mph. That means lumpy, choppy, messy conditions – not worth suiting up. Wave energy is moderate to moderately strong (346 to 1127), but with that wind, it’s a mess. For beginners, anything over 5ft gets too big, and at 7ft it’s expert-only anyway. Kite surfers might find it more interesting than paddle surfers.

Thursday the 3rd of September is marginal – morning has a light cross-on breeze and 5ft swell (244 energy), just okay.

Then we get a real highlight: Friday the 4th of September, early morning. It’s glassy – dead calm with a light NE breeze at 3 mph. Swell is small, 3ft from the NNW with an 8-second period (138 energy). Not big, but clean and fun. Water temp is around 68°F (a bit colder than normal, about 3°F colder), so grab a wetsuit. Crowds show up “sometimes,” so you might have a few out, but for glass like this, it’s worth it.

Saturday the 5th and Sunday the 6th of September are back to poor – cross-on, fresh breeze, small swell.

Monday the 7th of September morning is the next standout. Offshore wind from the SSE at 6 mph, clean conditions, and 3ft swell from the NW with a 10-second period (308 energy). Solid clean session for the early birds. Afternoon gets a light cross-on, but morning is the call.

Tuesday the 8th of September is small but clean – 2ft, offshore ESE wind, 10-second period (114 energy). Nothing special, but you can get a few.

Wednesday the 9th of September is the best of the stretch: morning has offshore wind from the ESE, 2ft swell with a very long 13-second period from the WNW (234 energy). Long-period groundswell like that will make small waves peel nicely on this beach-and-reef setup. Clean. Afternoon is also clean with 3ft at 12 seconds (307 energy) and a cross-off breeze. Two clean sessions back to back.

Thursday the 10th of September morning has moderate offshore wind (ESE 15 mph), clean, with 3ft from the WNW at 11 seconds (262 energy). Afternoon goes glassy (0 mph) with 3ft. Small, clean windows.

Friday the 11th of September finishes with a glassy afternoon – 2ft, 9-second period, no wind. Rideable but ordinary.

The true standouts: glassy Friday morning the 4th of September for the cleanest small waves, and Wednesday the 9th of September – both morning and afternoon – for that long-period groundswell and clean wind. That’s the best on offer after a rough 6-day start. The second week brings smaller but cleaner windows. Keep an eye on it – near-term calls are solid, later ones a bit less certain.
