Siriu Surf Forecast and Surf Report

Right, let’s have a look at what’s cooking for Siriu over the next couple of weeks. This is a beginner-friendly setup, fairly consistent, and exposed to the east. The water’s sitting at 62°, which is about 4° colder than usual for this time of year – that’s a notable chill, so you’ll want a good wetsuit for your session.

We’ve got a bit of a quiet start. Wednesday morning (the 16th of September) kicks off with a clean, glassy 4ft swell from the SSE, period at 8 seconds. The combined energy is low (277), so it’s not a powerhouse, but with the glassy conditions, this is a solid choice for a beginner to get some clean, fun rides. The wind stays favourable through the morning. Wednesday afternoon turns messy with a cross-onshore breeze, so morning is your window.

Thursday and Friday are marginal at best. Swell drops to around 3ft with cross winds and chop, so nothing to get excited about. Saturday the 19th brings moderate rain and a cross-onshore wind with a short-period 4ft swell from the ENE. This is a write-off. Sunday the 20th sees a big jump in energy – an 8ft swell from the NE with a period of 8 seconds pumps the combined energy to a strong 1396. However, the wind is cross, and the size is getting up there. For a beginner break, 8ft is pushing the limit – this is for experienced surfers only if they want to tackle it, but the forecast suggests marginal conditions.

Now, Monday the 21st is a true standout. Morning delivers a glassy 5ft swell from the ENE, period 9 seconds, with a combined energy of 357. The winds are glassy, the waves have a bit of push, and the break will be clean. This is your best bet for the first week – a real treat for a Monday sesh. Tuesday the 22nd goes flat and clean but weak, with a poor surf call.

The second week opens up with potential. Wednesday the 23rd morning brings a clean, cross-offshore wind with a 2ft swell from the SSE, but it’s a long-period 12-second groundswell. The combined energy is 409. This is a classic point-break style wave – long gaps between sets, but good shape. It won’t suit a beach break, but at a reef or point, it’ll be sweet.

Thursday and Friday (24th and 25th of September) are a write-off – strong cross-onshore winds and a messy 5ft to 5ft SSE swell. Saturday the 26th morning is another glassy moment with a 3ft SSE swell at 13 seconds and moderate energy (399). Very clean, but small.

Now, here’s a major caveat for the end of the month. On Tuesday the 29th of September, the swell is predicted to hit a massive 10ft from the S with a 12-second period. The combined energy is a colossal 3718. While the wind is glassy and the tide is right, the guidance clearly states this is simply too big for Siriu. Beginners should stay well away. This is for experts only, and even then, it might be more interesting for kite surfers than paddle surfers given the size and power.

Wednesday the 30th of September afternoon is the best of the entire forecast for experienced surfers. A 6ft SSE swell, 14-second period, glassy wind, and a combined energy of 1433. The call is "excellent surf conditions for experienced surfers." This is the one to mark. The long period will set up well at this exposed break, but expect big sets and long lulls.

Overall, the standout sessions are Monday morning the 21st (for cleaner, user-friendly waves) and Wednesday afternoon the 30th (for the experienced crew looking for quality). Crowds are sometimes an issue here, so get in early.
