Onrus Surf Forecast and Surf Report

Alright, this is Rusty, looking at the forecast for Onrus over the next couple of weeks.

Right off the bat, we’ve got some solid swell on the way, but it’s going to take a few days to really clean up. The real standout window is looking like the first week of August, with some absolute gems mixed in. There’s also a big, powerful pulse coming through later in the forecast, but that one’s gonna be too much of a handful for most.

We start off this Saturday, July 25th, with some decent 8ft SW swell at Onrus, but the wind is messy. It’s a cross-on breeze at 6 mph, making things choppy with a combined swell energy of 2378 (moderate wave energy). It’s surfable, but not great. The afternoon goes more onshore, dropping the quality.

Sunday the 26th is where it gets interesting. The morning brings a clean 7ft SW swell (1358 combined energy) with glassy conditions, light wind at 3 mph from the east. That’s prime, clean surf for experienced surfers. The water temp is about average for this time of year. The afternoon goes a bit cross-shore, but the morning is the pick of the first week.

Then things get wild. Monday and Tuesday, July 27th and 28th, are a write-off. We’re looking at a big, powerful SSW groundswell jumping to 10ft, with strong onshore winds and combined energy values in the thousands (4605 and 5963). It’s going to be a messy, blown-out mess, only for those who want a beating.

After that blows through, Wednesday the 29th and Thursday the 30th drop back down to smaller, junky 4ft to 5ft SW swells with cross-shore breezes. Just small, weak waves (495-1117 combined energy). Not worth paddling out for.

Now, here comes the first proper standout. Friday, July 31st and Saturday, August 1st are clean. We’ve got a small but clean 4ft SW swell with clean conditions. Friday morning has a light cross-offshore wind from the west, and Friday afternoon goes totally glassy! These are clean, user-friendly waves with minimal crowd pressure (just sometimes). The combined swell energy is low (around 444), but the conditions will be perfect for logging or a longboard.

The second standout is Sunday, August 2nd. We get a 5ft SW groundswell with a very long 16-second period, pushing combined energy to 1778 (moderate). But the real magic is the morning glass-off. With 0 mph wind from the WNW, it’ll be glassy perfection. That long period means better shaped, more powerful waves with long lulls, which suits a reef like Onrus perfectly.

Monday, August 3rd, is still good fun with clean 5ft SW swell (892 combined energy) and a light cross-offshore wind. Tuesday, August 4th, is another highlight. We get a clean 6ft SW swell (1149 combined energy) with a light offshore wind from the NW. That’s clean, lined-up surf for the experienced crew.

Then things get heavy. From Wednesday, August 5th, through to the end of the forecast on Sunday, August 9th, the swell becomes serious. A massive 10ft to 13ft SW/WSW groundswell kicks in, with combined energy readings over 5000 (strong wave energy). The wind is clean and offshore or glassy for most of it, but the problem is the size. For an exposed reef like Onrus, anything over 8ft is for experts only. A 13ft swell with a 14-second period at this break is going to be a big, powerful, intense session. This is not beginner territory at all.

So, the best on offer is first the clean, glassy small waves on Friday July 31st and Saturday August 1st, and then the absolute standout: the glassy, clean 5ft long-period groundswell on Sunday morning, August 2nd. Later in the week, the big stuff is on the cards for those who can handle it.

Rusty.
