Siriu Surf Forecast and Surf Report

Right then, let’s talk about Siriu. The forecast for the next couple of weeks is a bit of a slow starter, but there’s some real magic waiting if you’ve got the patience and the skill. The water’s sitting right around average for the start of September, so nothing wild there.

Right off the bat, the first few days are pretty grim. Wednesday the 2nd and Thursday the 3rd are a write-off – the wind’s messy and the surf is junk. The 4th and 5th are not much better, with small, weak swell and dodgy winds. It’s frustrating, but that’s how it goes sometimes.

The first ray of hope pops up on Saturday the 5th. The morning sees a 3ft south swell with clean, light cross-off breezes. The combined energy is moderate at 313, so it’ll be fun for a beginner-friendly session, but nothing to get too fired up about. That clean theme carries into Sunday morning the 6th, with a 4ft south swell and light cross-off wind. Again, small, but clean.

Now, if you’re an experienced surfer, listen up. Monday the 7th morning is the first real standout. The swell jumps to 7ft from the south, period is 10 seconds, and the combined energy is a solid 1310. That’s a powerful, strong swell. The wind is a light cross-off, keeping it clean. This is a session for those who know what they’re doing. 7ft is getting up there for beginners.

After that, it gets a bit messy again with onshore chop and poor conditions through the rest of that week.

But wait… Thursday the 10th morning. This is the big one. The swell is 8ft from the northeast, with an 8-second period – a real short period swell, so it'll be punchy. The wind? Dead calm. Absolutely glassy. The combined energy is 1205. That’s an excellent, expert-only session. It’s rare to get that kind of size and glassy conditions. If you’re an expert and you can paddle around Siriu, this is the best moment of the whole run. Friday the 11th is blown out by strong winds, so don't get caught out.

The following week, there’s a bit more promise. Monday the 14th morning looks good: 5ft swell from the northeast, glassy conditions again, and a combined energy of 519. That’s a very fun, clean session for those with a bit of skill.

Overall, the true standouts are definitely Monday the 7th morning for the powerful, clean 7ft south swell, and absolutely Thursday the 10th morning with the 8ft northeast glass. If you’re not an expert, stick to the smaller, cleaner windows around the 5th, 6th, and 14th.

Rusty.
