Onrus Surf Forecast and Surf Report

Alright, let’s get into it. The only break on the cards for this 16-day window is Onrus, a reef setup that’s exposed to the SW. It’s an inconsistent wave, so you’ve gotta be patient around here, but when it turns on, it can be a gem.

Water temp is sitting at 60°, which is about where you’d expect it for this time of year – nothing wild there.

The swell really finds its rhythm starting Sunday the 2nd of August. You’ve got a 4ft SW groundswell rolling in with a 12-second period, and the wind is dead glassy. The water is like a mirror. Onrus is exposed, so that SW direction is spot on. The energy is moderate (508), but it’s not about the size – it’s about the lack of any wind. This is the kind of session where you just sit out there and let the sets find you. That’s the standout moment in the early part of the outlook.

Monday morning the 3rd builds on that: 5ft of SW swell, 13-second period, and again glassy conditions. The energy is bumped up a notch (747). This is clean, lined-up reef surfing. The afternoon gets a bit of a cross-on breeze, so the morning is your window.

Tuesday the 4th is still surfable, with 5ft SW swell and a cross-off breeze in the morning keeping things clean, but the energy starts to drop (451).

Then Wednesday the 5th throws down a proper pulse. The swell jumps to 6ft from the SW, period stretching to a very long 16 seconds, and the wind is offshore from the WNW at 12 mph. The combined energy is strong (1831). This is a serious swell, and for a reef like Onrus, that long period will draw clean lines. The size is getting into intermediate territory, but it’s still manageable. The morning is the call here – the afternoon has a 19 mph breeze that makes it skatey. This is your second standout: a solid, powerful, clean swell.

Thursday the 6th and Friday the 7th see the swell pumping up to 10ft, which is too big for Onrus. The energy is massive (3009 and 2967), but the break can’t handle it. The Friday afternoon does see a 8ft SW swell with a clean cross-off breeze, but it’s still big for this spot. That’s when you need to be an experienced surfer or just watch from the shore.

The weekend of the 8th and 9th is a mix of way too big (12ft on Saturday, with 3718 energy) and then sloppy, strong wind on Sunday. Not worth paddling out.

There’s a bit of a lull Monday the 10th morning, with a small 4ft swell and glassy conditions (367 energy), but it’s a shadow of the earlier days. Then from Monday afternoon right through to the 12th, the swell just explodes – 15ft, 18ft, 12ft – all completely out of the question for Onrus. The energy numbers are off the charts (3791, 13505, 6568). That’s kite-surfing territory, not paddle surfing.

Things drop back down on Thursday the 13th of August. The swell is 6ft from the SSE, with a 14-second period, and a clean cross-off breeze. The energy is still strong (1703), but the size is back in range. The afternoon is even better with 5ft and the same clean conditions. That’s a good day for a reef.

The final weekend from the 14th to the 17th is mostly messy or small, with onshore winds and poor conditions. The 16th of August has a clean 5ft swell in the morning, but it’s marginal.

So, the absolute best of the bunch: Sunday the 2nd and Monday the 3rd of August for that glassy, small but perfect reef wave. Wednesday the 5th of August for the punch and power. Those are the sessions you don’t miss.
