Onrus Surf Forecast and Surf Report

Alright, let’s break it down in feet and degrees.

We’re starting a bit slow, but there’s a window of clean, fun surf coming up, and then a real big-boy swell hits later on. The first few days are pretty average with onshore winds and messy waves, so you’ll want to sit tight until Sunday morning.

The standout here is without a doubt Onrus – a reef setup that’s exposed to the SW. Water temp is sitting at 15°, which is about normal for the time of year, so no surprise there.

Alright, let’s run through it.

Wednesday 29 July and Thursday 30 July are write-offs. Cross-on winds, choppy, poor surf. Swell sits around 4 ft to 6 ft but the wind just ruins it. Not worth paddling out.

Friday 31 July is still marginal. Morning shows a small 4 ft SW swell (12 seconds) with a cross breeze, and the afternoon stays poor. Not much to get excited about.

Saturday 1 August is a little better but still only marginal. Light winds, a 4 ft SW swell (14 seconds) in the morning, but it’s not clean enough to call it good.

Sunday 2 August – now we’re talking. Morning is clean with a light cross-offshore breeze and a 4 ft SW swell (13 seconds). The afternoon goes glassy, and that is a rare treat. Smooth, clean lines. The combined energy is moderate (424 in the morning, 385 in the afternoon). This is the first real window of quality surf.

Monday 3 August is even better. Glassy conditions both morning and afternoon, with the swell pushing 5 ft (13 seconds) in the morning and a solid 4 ft WSW swell in the afternoon. The combined energy hits 647 in the morning – that’s moderate but with that glassy wind, it’s going to feel way better. This is a top day for Onrus.

Tuesday 4 August drops off a bit. Clean in the morning but only 3 ft, and the afternoon has a very long period 16-second swell but only 2 ft – not enough push for a good session.

Wednesday 5 August – here we go. Morning sees a 8 ft SW groundswell (14 seconds) with offshore winds from the NNW at 15 mph. The combined energy is strong (2356). This is for experienced surfers only – over 8 ft and it’s expert territory. The afternoon is huge: 10 ft, but the wind cranks up to 31 mph from the NW, which is a near gale. That’s too big and too windy for Onrus, but the morning session is a serious standout.

Thursday 6 August to Sunday 9 August – the swell stays big, 12 ft to 13 ft, with clean conditions but the size is way too much for most. The combined energy is massive (up to 7827). This is expert-only, and even then, it’s borderline. The reef will be handling it, but you’ll need to be on your game.

Monday 10 August – a messy day. Onshore winds, 16 ft swell, but it’s a washing machine. Avoid.

Tuesday 11 August – still big, 12 ft to 10 ft, but the afternoon turns glassy. That’s a rare combination but again, only for experts. Combined energy is still very strong (2797 to 3260).

Wednesday 12 August – a drop in size, 5 ft, but cross-on winds make it marginal. Not great.

Thursday 13 August – back to big conditions. 12 ft SW groundswell with a very long 15-second period, and moderate offshore winds. That’s a clean, powerful, expert-only day. The combined energy is 4645 – proper strong.

So, to sum it up: the best windows for a good session are Sunday 2 August through Monday 3 August – clean, glassy, fun-sized waves. For the experienced crew, the Wednesday 5 August morning session is a standout. After that, it’s either too big or too windy until the very end of the forecast.
