Onrus Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s have a look at what’s been cooking for our local spot.

We’ve got a pretty solid run of surf coming up, but it’s a bit of a mixed bag with some real standouts and a few days where you might want to take the dog for a walk instead. The main event is definitely an excellent pulse of long-period SW groundswell that hits mid-week, but you’ll need to be on your game for that one.

First up, Monday morning the 3rd of August at Onrus, and it’s a beauty to kick things off. We’re looking at a clean 5ft SW swell, with a long 13-second period pushing through. The wind is glassy out of the ENE at just 3 mph, so the surface is going to be perfect. The combined energy is moderate (747). It’s a reef break, so it can be a bit inconsistent, but when it’s this clean and lined up, it’s a proper treat. You might see a few others out there, as it can get crowded sometimes, but for a Monday morning session, it’s worth the paddle.

Tuesday the 4th keeps things ticking over nicely. Morning shows a 5ft SW swell, still with a decent 11-second period, and a light cross-offshore wind from the W. It’s clean (451). The afternoon glass-off is even better with a light southerly, though the swell drops a touch to 4ft. Good, workable waves for the intermediate crew.

Now, here’s the standout. Wednesday the 5th of August. This is the one to circle on the calendar. The morning brings a solid 7ft SW groundswell, with a very long 16-second period. The energy is strong (2034). And the wind? Pure offshore from the NW at 12 mph. That’s an expert-level session right there – clean, powerful, and lined up. The afternoon is just as punchy with a 7ft swell and 15-second period, but the wind picks up to 19 mph from the WNW, still offshore. It’s going to be a bit more challenging to handle, but the wave quality will be top-tier for those who can handle it. This is for experienced surfers only.

Thursday the 6th through Sunday the 9th, the swell gets seriously big. We’re talking 10ft SW swell with energy readings in the 2000s and 3000s. The wind is mostly light and cross-shore, but the size is just too much for this break. Unless you’re absolute charging and have a big-wave board, it’s a no-go. Conditions deteriorate Sunday with strong onshore winds and rain, so that’s a hard pass.

We then hit a bit of a lull from Monday the 10th through Tuesday the 11th. The swell drops right off, and the wind is onshore or cross-onshore. Poor conditions all round. Wednesday the 12th is still messy with onshore wind, though there’s a 5ft SW swell, it’s just not clean enough to get excited about.

Another big pulse shows up on Thursday the 13th of August, with 10ft SW swell and a 15-second period. The energy is very strong (4185). But again, it’s too big for the reef and the wind is cross-onshore. For experts only, and even then, it’s a risky call.

Friday the 14th and Saturday the 15th are a bit of a mixed bag. Friday has some size but onshore wind. Saturday the 15th, however, shows some promise. The afternoon session is worth a mention – a 6ft WSW swell with a 12-second period, and it goes glassy with a light SSE wind. The combined energy is moderate (769). That’s a clean, fun wave for the weekend.

Sunday the 16th and Monday the 17th are small and mostly onshore or calm. Monday the 17th morning is glassy with a 4ft WSW swell, but it’s low energy (395). Tuesday the 18th morning sees a jump back up to 8ft WSW swell with a 13-second period and a strong NW offshore wind at 22 mph. The energy is strong (1960). That’s a powerful, clean, expert-only session, but it’s a long way out, so keep an eye on the charts.

Bottom line: The absolute best session in the whole 16-day window is Wednesday morning, 5th August at Onrus. That’s your standout. Get the 7ft SW groundswell, the 16-second period, and the offshore wind. It’s gold. The Saturday afternoon the 15th is a solid secondary option for a cleaner, smaller wave. Don’t bother with the huge days unless you’re a gun.

Rusty.
