Onrus Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what Onrus has in store for us over the next couple of weeks.

Right off the bat, we’ve got a bit of a quiet start. Thursday and Friday this week are pretty much a write-off – there’s some small southwest swell around, but the wind is cross-onshore and it’s all a bit messy and choppy. Not worth paddling out for.

Things start to turn the corner on Saturday the 1st of August. It’s not big, with waves around 4ft from the southwest, but the wind swings cross-offshore in the morning and the conditions turn clean. The energy is moderate (551), and it’s looking like a nice little session for an intermediate surfer. The water temp is about average for this time of year, so nothing to worry about there.

Sunday the 2nd is even better in the afternoon – glassy conditions with that 4ft southwest swell, moderate energy (443), and a clean face. That’s a solid window for a few relaxed ones.

But the real standout that’s got me talking is Monday the 3rd of August. We’ve got 5ft of southwest swell, glassy conditions all morning with barely a breath of wind, and the combined energy is moderate to strong (599). It’s clean, it’s punchy, and it’s going to be fun for the intermediate crew. This is the best call of the first week.

Tuesday the 4th keeps the clean theme going with cross-offshore wind and similar sized swell. The energy drops a little through the day, but it’s still a good, surfable window.

Now, hold onto your board – Wednesday the 5th of August kicks off a proper run of big swell. We’re talking 8ft on Wednesday morning with a 16-second period and a nasty 3486 energy reading. That’s a lot of water moving, and it’s only going to work for experienced surfers. By the afternoon, it’s 12ft and too big for this break. Then Thursday, Friday, and into the weekend the swell stays oversized, often over 10ft, with huge energy numbers well into the thousands. For a reef break like Onrus, this is expert territory or just a full-on washout for the rest of us. The winds aren’t always terrible, but the size is the boss here.

We get a bit of a lull into the second week. Saturday the 8th and Sunday the 9th are still too big and messy, with cross-shore and onshore winds spoiling things. By Monday the 10th it’s still big and lumpy; don’t bother.

Finally, we get another clean-up. Wednesday the 12th of August is a beauty – 5ft of southwest swell, glassy conditions, and strong energy (1299). That’s a very good day for experienced surfers, and it’s clean as a whistle. Thursday the 13th looks even more inviting with smaller 3ft to 5ft swell, glassy or clean conditions, and good energy – a proper fun day for intermediates.

The long-range standout? That Wednesday the 12th and Thursday the 13th combo is the one to circle. It’s a week and a half out, so things can shift, but the signals are strong for clean, manageable swell. Keep an eye on it.

Overall, there are some proper gaps here – the first couple of days are dead, and the big swell window from the 5th to the 10th is too serious for most. But the clean windows on the 1st, 2nd, 3rd, and then again on the 12th and 13th are worth wetting a wetsuit for. Onrus is an inconsistent reef, so when it lines up, you take it.

Rusty.
