Onrus Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s have a look at what’s coming up for Onrus over the next couple of weeks.

We’re kicking off with a bit of a slow start. Saturday the 29th and Sunday the 30th are pretty average. The swell is there, but conditions are all over the shop. Saturday morning has a 4ft swell from the WSW with a 13-second period, but it’s cloudy with a cross-off wind and the energy is weak (705). The afternoon turns into a mess with some rain and a 7ft SW swell that’s cross-shore and choppy, and the energy is moderate (1835). Sunday morning cleans up with a clear sky and a 8ft SW swell, but the onshore wind and energy (1583) still don’t make it a great paddle. Sunday afternoon stays full and choppy. Not worth rushing out for.

Now we get to the good stuff. Monday the 31st is where it starts to turn. The morning is glassy, absolute perfection. That 6ft SW swell with an 11-second period and low energy (830) will be clean and fun. A real treat for those who can get out. The afternoon is still decent with a 6ft SW swell, but a light cross-shore wind gives it a little ripple.

Then Tuesday the 1st of September. This is a standout. The morning has an 8ft SW swell with a 13-second period and offshore wind. The energy is strong (2031). It’s clean and powerful. This is for experienced surfers only – it’s a solid size. The afternoon gets even bigger at 10ft, but it’s a bit too much for the break and the wind turns cross-off. Still, the morning window is the pick of the first week.

Things get blown out from Wednesday the 2nd through to Saturday the 5th. Strong onshore and cross-on winds, rising energy numbers (up to 3020 on Wednesday morning), but the quality is poor. A lot of chop and not much fun. The surf is around 7ft to 10ft for most of that, but it’s messy. If you’re into kiting, this might be your window, but for paddle surfing, it’s a miss.

Sunday the 6th of September brings a change. The morning is glassy again with a 5ft SW swell and a very long 15-second period. The energy is moderate (1107). That long period groundswell will be better for the reef, but it might close out on the beach. Still, it’s clean and inviting. The afternoon has a 4ft SW swell with offshore wind, so it’s a solid day.

The second week has a couple of serious highlights. Tuesday the 12th of September is a big one. Morning has a 7ft WSW swell with a 14-second period and offshore wind, energy is strong (1894). The afternoon is also excellent with the same size but a cross-off wind. Both sessions are clean and powerful. Then Sunday the 13th of September is the real standout of the whole outlook. Morning has a 8ft SW swell with a 13-second period, light cross-off wind, and energy is strong (2036). The afternoon matches it. This is the best on offer – clean, solid, and consistent. It’s for experienced surfers.

The water temperature is sitting at 59°F, which is about 1°F cooler than usual for this time of year. That’s not a big deal, just a little on the fresh side, so grab a thicker wetsuit.

Remember, Onrus is a reef break that’s inconsistent and can get crowded sometimes. It’s exposed to the SW swell, which is exactly what we’re getting. The optimum swell direction is from the SW, so these swells are lining up perfectly.

So, the pick of the windows: Monday the 31st of August morning for a glassy session, and Sunday the 13th of September all day for the biggest, cleanest, and most powerful waves. The long-range stuff around the 12th and 13th is promising, but keep an eye on it – it’s a bit further out.

Rusty.
