Onrus Surf Forecast and Surf Report

Alright folks, Rusty here. Let's talk about what's cooking at Onrus.

We've got a mixed bag ahead. The week starts a bit slow, but there’s some proper swell on the horizon for the experienced crew, especially if you’re patient. The water temp is sitting at 59°, which is a bit colder than what we’d normally expect for this time of year, so you’ll want a decent wetsuit.

The first couple of days are pretty average. Saturday the 22nd has waist-high swell around 4ft from the SSW with a 12-second period, but the cross-off shore breeze just makes it marginal. Not worth getting too excited about.

Sunday the 23rd morning is your first real standout. The wind goes glassy from the ESE at just 3 mph, and the swell jumps to a solid 7ft from the SW with a 13-second period. The wave energy is strong (1527), and the conditions will be glassy. This is excellent for experienced surfers, but at over 5ft, it’s getting a bit much for beginners. It’s a reef break that can be inconsistent, so you’ll need to pick your moments.

We then hit a rough patch from Monday the 24th through Wednesday the 26th. Onshore winds and generally poor, lumpy conditions mean you’re better off doing something else. Thursday the 27th morning offers a brief window of clean, glassy 4ft waves, but the energy is weak (634) – it’s more of a longboard and recovery session.

The next real standout hits Saturday the 29th morning. We get a clean, moderate offshore breeze from the NW and a solid 4ft swell from the WSW, but it’s packing a 14-second period and strong energy (1109). The offshore wind will groom it into nice lines. This is another one for the experienced crew.

Sunday the 30th sees the swell jump up. The morning has 10ft from the SW, but the forecast flags it as too big for this break. The afternoon, however, is a solid 8ft from the SW with a clean offshore wind from the WNW. Excellent for experienced surfers, but that’s a big wave.

The first week of September brings more size. Wednesday the 2nd afternoon is a monster, but not for paddling. You’re looking at a 13ft groundswell from the SW with an 18-second period. The combined energy is extreme (11107). The wind is glassy, but this is strictly for the big-wave chargers or maybe the tow crew. For the average punter, it’s a no-go.

Thursday the 3rd and Friday the 4th continue with strong, clean offshores and big swell (12ft and 7ft respectively), but again, the size will limit it to experts only. Saturday the 5th morning offers a slight drop to a still-chunky 8ft from the SW with a clean cross-off breeze.

Overall, the best windows for experienced surfers are Sunday the 23rd morning and Saturday the 29th morning. For the well-equipped expert, the sessions around the 2nd to the 5th of September are massive but will demand respect. The inconsistent nature of this reef means you might wait a while for the set, but when it comes, it’ll be worth it.

Rusty.
