Onrus Surf Forecast and Surf Report

Alright, Rusty here. Let’s talk about what’s coming our way for Onrus.

First up, things kick off on Sunday, the 16th of August, with a bit of a slow start. We’ve got some 6ft swell from the WSW, period around 14 seconds – that’s a nice groundswell pulse, but the wind is a cross-off at 16 mph, and it’s making things feel a little marginal. The water’s sitting at 57°, which is a bit colder than normal for this time of year, so you’ll want a good steamer. The combined swell energy is pretty strong, reading 1525. Not a total write-off, but not the best of the run.

The real standout here is Monday morning, the 17th. Onrus is a reef setup, and with an 8ft WSW swell at 13 seconds, and a clean offshore wind from the NW at 9 mph – that’s proper. The energy jumps to 2084, and the conditions are described as excellent for experienced surfers. This is the pick of the week for sure. Swell direction matches the optimum SW direction, and it’s going to be clean. Just be aware, crowds are sometimes an issue here.

Tuesday the 18th and Wednesday the 19th see the swell holding around 8ft from the SW, but the wind turns onshore or cross-shore, so it gets messy. Not worth getting excited about. Thursday the 20th, the swell jumps to 10ft from the SW, but that’s actually too big for this break, and the wind is onshore by afternoon. Friday the 21st is smaller again, around 7ft, but still a bit choppy.

Saturday the 22nd has a strange one – morning wind is a strong offshore NW at 22 mph with 5ft swell, but the energy is low at 469, and the score is poor. Then Saturday afternoon, the swell jumps back to 10ft from the SW with an 19 mph offshore, but again, it’s too big for the break.

Sunday the 23rd and Monday the 24th are absolute monsters – 13ft and 12ft swells from the SW, with very long periods up to 16 seconds. That’s serious energy (8684 on Sunday morning), but it’s way too big for Onrus. Not for paddling.

After that, the surf settles down through the end of the month. There’s a nice moment on Saturday morning, the 29th of August – 8ft swell from the SW, period 13 seconds, and glassy conditions with a 3 mph SW wind. That’s another solid window for experienced surfers. The energy is 1656, and it’s clean. That’s your second standout.

Sunday the 30th has a 7ft morning with offshore winds, decent, but then the wind changes. Monday the 31st sees another big pulse – 12ft from the SW – but the wind is cross-on and the conditions are poor.

Overall, the best bets are Monday the 17th and Saturday the 29th – both mornings, both clean or glassy, with solid groundswell. Onrus is an exposed reef that can get crowded when it’s good, and it’s inconsistent, so when it lines up, you want to be there.
