Siriu Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s coming up at Siriu. We’ve got a bit of a mixed bag over the next couple of weeks, so I’ll walk you through it day by day.

Right now, the surf is pretty average to start. Wednesday 12th August has a bumpy 6 ft SSE swell, but it’s cross-shore and cross-chop, so it’s not really worth paddling out for. The combined energy is moderate (931). Thursday 13th August is the first real standout. That morning, the swell holds at 6 ft from the SSE, period stretches to 14 seconds, and the wind goes glassy – dead calm from the SW. That’s going to be clean, smooth, and punchy. The energy jumps up to 1331. This is the best session on offer in the first week. That afternoon, the wind turns cross-offshore, but it’s still in the good range at 6 ft, though the magic fades slightly.

Friday 14th and Saturday 15th are messy. Onshore winds, lumpy conditions, and the energy drops. The swell direction swings to the east on Saturday, with a short period of 8 seconds, so it’s weak and choppy. Sunday 16th is poor, and Monday 17th stays choppy and bumpy despite the swell size climbing to 8 ft on Monday afternoon. That’s getting big, but with cross-shore winds and a short period, it’s just a messy, lumpy wall. Not for beginners.

Tuesday 18th and Wednesday 19th are a write-off – small, onshore, and choppy. The energy bottoms out.

Then we get another standout. Thursday 20th August morning: the wind drops to dead calm, glassy as glass, and the swell is 6 ft from the south with a 9-second period. The energy is moderate (797), and the conditions are described as ‘very good’. That’s a clean, smooth morning session. Friday 21st morning is also very good: 5 ft from the south, 12-second period, light cross-offshore wind from the SSW. Clean lines, good shape. The energy is 685. That’s a solid session.

Saturday 22nd and Sunday 23rd are smaller, dropping to 3 ft and then 1 ft, with clean winds but very ordinary surf. Not worth getting excited about.

Monday 24th is a no-go.

Then Tuesday 25th August morning is another surprise: the wind goes glassy again, with a 5 ft SSE swell, 13-second period, and energy of 914. That’s a very good, clean morning. The afternoon gets a little cross-on, but the morning is the pick.

Wednesday 26th and Thursday 27th are bigger – 7 ft to 8 ft from the east, with short 8-9 second periods and strong cross-offshore winds. The energy is high (over 1300), but the short period makes it a bit tricky. It’s clean, but it’s punchy and fast. That’s for the experienced lot.

The water temperature here is about average for the time of year, nothing unusual.

So, the two true standouts are Thursday 13th August morning – glassy, 6 ft, 14-second groundswell from the SSE. And Tuesday 25th August morning – glassy, 5 ft, 13-second SSE swell. Both are clean, consistent, and have good energy. The rest of the window is a mix of onshore junk and small surf, with a few clean but smaller days in between.

Rusty.
