Onrus Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Onrus.

We’ve got a solid run of swell on the way, but it’s not all going to be easy to tap into. The early part of the outlook is dominated by a big, powerful SW groundswell that’s going to be a handful. The break itself is a reef setup, so it can handle a bit of size, but when it’s pushing over 8 feet, it’s strictly for the experienced crew. The water temp is about average for this time of year, no real surprises there.

The first real chance to get amongst it kicks off on Saturday morning, the 8th of August. We’ve got a clean 8 feet of SW swell rolling in with a 13-second period, combined energy of 2158 (moderate-to-strong), and a nice offshore NW breeze. That’s excellent, clean surf for those who know what they’re doing on a reef. This is the standout of the early window. The afternoon gets messy with a cross-shore wind, and the swell jumps to 12 feet. That’s way too much for this spot and the rating reflects that.

Sunday and Monday are write-offs. Onshore winds, lumpy, choppy, and just plain ugly. That run of poor conditions lasts a few days. Tuesday the 11th, Wednesday the 12th, and Thursday the 13th are all poor to marginal. The winds are mostly cross-on or cross-shore, and the swell is still big enough to be a problem. Thursday the 13th shows some glimmers with a 8 feet SW swell and a 19-second period, but the cross-shore wind and marginal tide call keep it from being a goer.

Now, Friday the 14th of August. That afternoon is pure magic. The swell drops to a manageable 5 feet from the WSW, with a 14-second period, and the wind goes glassy – completely off. The combined energy is 1058 (moderate). That’s the best of the whole outlook. Clean, offshore, perfect reef conditions for an intermediate to advanced surfer. This is the one to circle. The morning is also a decent option with a light cross-shore, but the glassy afternoon is where it’s at.

Saturday the 15th and Sunday the 16th have some clean offshore options in the morning, but the swell is a bit smaller and the energy is dropping. The 16th has an 8 feet WSW swell, but the wind is onshore, so it’s a miss.

The second week gets a bit more patchy. Monday the 17th afternoon goes glassy again with a 6 feet WSW swell, 13-second period, and 1066 energy. That’s another clean, excellent session. Wednesday the 19th morning is also glassy with a 6 feet swell, 13-second period, and 1103 energy. Another good one for the crew who can wait.

It’s not all perfect, though. The wind swings around on the 20th with a fresh offshore WNW breeze, but the swell is getting bigger, pushing 8 feet to 8 feet. That’s a lot of power (2898 energy) and it’s marginal. The 22nd of August sees a massive 13 feet WSW swell, combined energy hitting 5362 (very strong). That’s a big, dangerous wave, only for the true experts. The 23rd has a 12 feet SW swell with a clean offshore wind, but again, that’s big.

So, to wrap it up: the absolute best of the bunch is the glassy, clean afternoon session on Friday the 14th of August. The Monday afternoon the 17th and Wednesday morning the 19th are also excellent, clean alternatives. The early Saturday morning on the 8th is a solid, powerful option for the experienced. The rest is either too big, too windy, or just marginal. Don’t even think about the 22nd unless you’re a pro.

Rusty.
