Siriu Surf Forecast and Surf Report

Righto, Rusty here. Let's have a look at the surf outlook for Siriu.

Things start a bit average, but there's a real window of opportunity for the experienced crew later on. The first few days are a bit of a write-off with messy winds, but there's a couple of standouts to keep an eye on.

Friday 14 August afternoon is the first real highlight. Swell is up around 7ft from the SSE with a solid 13-second period, pumping moderate energy (1591) into the beach. The wind goes glassy, ENE at just 3 mph, so it'll be clean as a whistle. This is proper groundswell territory – longer lulls between sets but the waves will have shape and punch. It's on the bigger side for beginners but for the experienced surfer, this is the pick of the early run. The break is exposed to the east, and that SSE direction is bang on what it wants.

After that, the forecast goes a bit flat and ugly. Saturday 15 August through to Wednesday 19 August is mostly a mess of cross and cross-onshore winds over 9 mph making things choppy, with energy dropping off from 1331 to barely 200. There's a window on Thursday 20 August morning where it's glassy again – E wind at 3 mph – but the swell has dropped to just 3ft with weak energy (190). Surfable but very ordinary.

Things really look poor from the 22nd onwards with tiny wave heights. Then from Monday 24 August, a new pulse arrives. Afternoon sees a 5ft S groundswell with a 11-second period, and the wind goes cross-offshore from the SW at 9 mph. The combined energy is moderate (638) and the conditions are clean. It's not huge but it's well-shaped and empty-looking.

Tuesday 25 August is the standout of the second week. Morning has 4ft S swell, 11-second period, cross-offshore wind from the SW at just 6 mph – clean, glassy faces. The energy sits at 530 but the quality will be there. Afternoon brings a jump in size to 6ft from the E but the period drops to 7 seconds, so it'll be shorter, steeper windswell – still clean with light SSW winds at 6 mph and 713 energy. Not as refined as the morning but still a decent session.

Wednesday 26 August afternoon gets a serious bump – 7ft from the ESE at 8 seconds, cross-offshore wind from the SSW at 9 mph, and strong energy at 1154. That's a powerful, clean, slabby wave. The period is short so it'll be a bit dumpy and sectiony, but for experienced surfers in clean conditions, that's a proper session.

The final days from 27 August onward look like they deteriorate again with onshore winds and dropping energy.

So the honest call: Friday 14 August afternoon is the absolute best early window – glassy, solid groundswell, and quality. Then Tuesday 25 August morning is the pick of the second week – clean, well-shaped, and mellow. The 26th afternoon is also a standout for power, but it's strictly for the experienced.

Enjoy, and stay safe out there.
