Castelejo Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at the forecast for Castelejo. This is a beach and reef setup that’s very consistent, exposed to the open ocean, and works best with a swell from the NW. The water temperature is about average for the time of year, so nothing out of the ordinary there.

We’ve got a bit of a slow start, with no real surf on offer for the first few days. Thursday the 27th of August sees some swell, but it’s sloppy and messy with strong cross-shore winds. Thursday morning has a 5ft W swell at 8 seconds, but it’s chopped up with a fresh 30 km/h wind, so it’s not worth paddling out. Friday morning is a bit better, with a 7ft WNW swell at 10 seconds, but it’s still cross-on and windy. The energy is moderate (1060), but the conditions just aren’t there.

The weekend doesn’t bring much hope either. Saturday the 29th through to Monday the 31st are all blown out with strong onshore winds, and the swell is small and weak. The combined energy drops off to below 300, so it’s a flat, messy affair. Tuesday the 1st of September picks up a bit of size, with a 6ft NW swell, but the wind is howling from the NNW at 40 km/h, making it a complete write-off.

Things start to look up by Thursday the 3rd of September. The morning still has a fresh 30 km/h wind, but it’s cross-off, and the swell is a clean 5ft from the NW. The wind swings lighter in the afternoon, with a light 10 km/h ENE cross-off, and the swell drops to 5ft from the NNW. The combined energy is low (238), but the conditions are clean. It’s a small day, but it’s the first decent window.

Friday the 4th is more of the same: small, clean, and light winds. The 4ft NW swell is knee-high, but it’s surfable.

Now, here’s the standout. Saturday the 5th of September is the best on offer. The morning shows a 2ft NW swell, but the period is a long 13 seconds, and the wind is a gentle 15 km/h ESE cross-off. The energy is low (248), but that long period groundswell will wrap nicely into the reef. The afternoon is even better: a 3ft NW swell at 12 seconds with a gentle 15 km/h SE offshore wind. The combined energy is 364, and it’s clean. This is a classic small, glassy, offshore day for the reef.

Sunday the 6th keeps the good vibes going with a 4ft NW swell at 12 seconds in the morning, and a gentle cross-off wind. The afternoon sees similar conditions with a 4ft NW swell and a 15 km/h SE offshore. The energy is moderate (469), and it’s clean. This is a solid weekend window.

Monday the 7th is the last of the good stuff, with a tiny 2ft NW swell at 10 seconds in the morning, but the wind is a light 5 km/h from the south, making it glassy. The afternoon is even better, with a 2ft NW swell and glassy conditions.

After that, the forecast gets messy again from Tuesday the 8th onward, with onshore winds and lumpy conditions. The 9th and 10th have some swell, but the wind is onshore and the period is short.

So, to wrap it up: the first week is a write-off, but the weekend of the 5th and 6th of September is your best bet. The standout is Saturday afternoon, with a clean, offshore 3ft NW swell at 12 seconds. It’s small, but it’ll be perfect for the reef. Keep in mind, with a long period like that, the sets will be spaced out, making paddling easier. The crowd profile is “sometimes,” so you might have some company, but it’s not a zoo.

Rusty.
