Onrus Surf Forecast and Surf Report

Righto, Rusty here. Let's have a look at what Onrus has cookin' over the next couple of weeks.

It's a slow start, I won't lie to ya. The first couple of days are pretty average, with Wednesday 26th a write-off thanks to a fresh cross-onshore breeze making a mess of things. Thursday 27th is where it starts to look a bit more promising. We get a clean, 5ft S swell with a 12-second period, and a light cross-offshore wind. The wave energy is moderate at 781. It's gonna be a decent session for the intermediate crew; the swell's not too nasty, but there's some push to it.

Friday 28th morning is the first real standout in the first week. It's glassy, dead calm, with a 4ft S swell. The period is a touch short at 11 seconds, but that glassy surface is a gift. The combined energy is on the lower side of moderate at 493, so it'll be a cruisy one, but the quality of the wave will be there.

The weekend sees a bit of a bump. Saturday 29th afternoon pushes up to 6ft from the WSW with a 14-second period and a clean cross-offshore breeze. The wave energy jumps right up to 1570 (moderate to strong), so there's some grunt, but the wind is favourable. Sunday 30th gets bigger but the wind goes against it; that 7ft swell is getting cross-onshore, so it'll be lumpy.

Now, the big news. The first few days of September are where things get serious. Monday 31st August morning looks clean and solid with a 6ft SW swell and light offshore wind. But the highlight—and I mean the standout—is Tuesday 1st September. We're looking at an 12ft SW swell early, with a very long 14-second period, and a strong offshore wind from the NW at 25 mph. The combined energy is a massive 4542. This is serious, expert-only territory. It's too big for anyone but the very experienced. The wave will be a beast, but it's going to be clean, powerful, and demanding. Wednesday 2nd holds similar size, but the wind gets a bit messy.

After that, the wind turns against us from Thursday 3rd September through to Saturday 5th September, with solid cross-onshore breezes ruining a lot of the swell. We've got a real low point here with a few days of poor surf. Things settle down a little on Sunday 6th September morning with a glassy 4ft SSE swell, but it's a short period (8 seconds) and low energy.

For the rest of the second week, it's mostly onshore or cross-shore junk. Nothing worth writing home about until maybe Thursday 10th September when we get a fresh offshore wind, but the swell is tiny at 2ft with a very long 16-second period. It could be glassy clean, but there's just not enough water to get you going seriously.

The standout to aim for? No question, it's Tuesday 1st September. That offshore, solid groundswell is the pick of the whole forecast window. If you're an expert and like it heavy and clean, that's your day. For everyone else, Thursday 27th and Friday 28th August offer the best chance at a fun, manageable wave. The water temperature's about average for this time of year.
