Onrus Surf Forecast and Surf Report

Alright, Rusty here, let’s talk about Onrus.

First up, the water’s sitting at 60°F, which is pretty normal for this time of year, so no nasty surprises when you jump in.

It’s a quiet start to the period. Tuesday afternoon (August 4th), there’s a little 4ft SW groundswell sneaking in with a glassy ESE breeze – total wave energy is weak (344). It’s not big or powerful, but it’s clean, and sometimes that’s all you need for a fun little session on the reef.

The standout of the whole run is Wednesday morning, August 5th. We’ve got a solid 7ft SW groundswell rolling in with a long 16-second period, packing moderate energy (1986). The wind is nuking offshore from the NW at 12 mph. This is proper groundswell, and Onrus loves it from the SW. It’s an intermediate reef setup, but this one is for experienced heads – the lines will be clean, the walls will be there, and it’s going to be a bloody good session. Wednesday afternoon is still in the mix at 7ft and a fresh offshore WNW wind, but that morning window is the one.

Thursday August 6th through Friday August 7th, the swell pumps up to 10ft from the SW, but here’s the kicker – it’s too big for Onrus, and the wind is onshore. The combined energy jumps into the thousands (strong), but it’s not for paddle surfing. A session like that is more interesting for the kite crew.

Saturday August 8th offers a window for the brave. Morning has 8ft SW swell (13 seconds) and glassy conditions – clean, but that size is only for experts on a reef. Afternoon sees it push to 10ft with a cross-off wind, but again, it’s getting dicey.

Sunday August 9th is a write-off with 10ft to 12ft and strong cross-onshore winds. Monday through Wednesday (Aug 10-12) is messy or marginal with onshore winds and lumpy conditions. Not recommended.

We hit a quiet patch mid-week, but Thursday August 13th to Saturday August 15th brings a really nice run of clean, manageable surf. On Thursday morning (Aug 13th), the swell is 5ft from the SW with an 18-second period (moderate energy at 2301), and a gentle cross-shore wind. It’s clean, it’s got power, and it’s not too big. Friday morning (Aug 14th) is even better – 5ft from the WSW, but a light cross-off breeze from the NNE makes for clean conditions. Friday afternoon goes glassy with 5ft waves. The whole weekend (Aug 15-16) stays in the 4ft to 6ft range with offshore or cross-off winds – classic winter sessions, nothing huge, just clean, fun reef waves.

Now for the long-range. Monday August 17th has a massive pulse of 12ft from the WSW with a 13-second period and total energy of 7577 (very strong). The wind is offshore from the NNW. That is a beast of a swell, but for Onrus, 12ft is only for experts and even then, it’s pushing the limit. Keep an eye on it, but don’t get too excited – that kind of power is more of a promise than a certainty at this range.

The rest of the second week (Aug 18-19) stays big (10ft to 12ft) but with cross-off or cross-on winds. It’s a lot of water moving, but not the cleanest conditions for the reef. For a spot that’s inconsistent, the first half of the period delivers if you pick your windows.

Stay stoked,
Rusty
