Onrus Surf Forecast and Surf Report

Right then, let’s talk about Onrus. This is a reef setup, exposed to the SW, and it’s got a bit of a reputation for being inconsistent, so when it does fire, you want to be on it.

The forecast kicks off on Thursday the 6th of August, and to be honest, it’s a frustrating start. There’s a hefty 10ft SW swell rolling in with a period of 13 seconds, and the combined energy is strong at 3029. The problem is, that’s just too much water for this break. It’s going to be too big, even with glassy conditions in the morning and a light 5 km/h SSE wind. The afternoon stays big with a 12-second period and cross-on wind, making it choppy. Friday is more of the same – still too big at 10ft, even with a clean cross-off wind on Friday afternoon.

Now, Saturday the 8th of August is where it gets interesting. The morning sees the swell drop to 8ft from the SW with a 13-second period. The wind is offshore from the NW at 20 km/h, and the forecast says it’s excellent for experienced surfers. The combined energy is still high at 2012, but that offshore wind will clean things right up. This is the standout of the early period, but understand, at 8ft, this is not for beginners – you need to know what you’re doing on a reef.

Sunday and Monday get blown out with strong cross-onshore winds and poor conditions. Tuesday the 11th stays messy with fresh cross-onshore winds and lumpy surf.

The next real window opens on Wednesday the 12th of August. The swell has backed off to 6ft from the SW, but the period jumps up to a very long 18 seconds. That’s proper groundswell energy, and with a light NE cross-shore wind, it’s going to be lined up but maybe a bit straight for the beach. The combined energy is moderate at 1927. It’s marginal due to tide, but worth a look.

Thursday the 13th of August morning is another good call. The swell is 7ft from the SW, period 16 seconds, and the wind is cross-off from the NE at 10 km/h. Clean conditions and excellent for experienced surfers. The energy is moderate to strong at 2116.

Then we get a nice run from Friday the 14th through Monday the 17th of August. Friday morning has clean 4ft WSW swell with a cross-off wind, and Friday afternoon goes glassy with 4ft. Saturday the 15th morning stays clean with 5ft. Sunday the 16th is glassy all day with 5ft to 5ft WSW swell – that’s the pick of the second week for a more relaxed session. Monday the 17th morning has offshore wind and clean 5ft, and Monday afternoon sees the swell bump to 7ft with a cross-off wind, excellent for experienced surfers again. The energy is moderate to strong at 1207.

After that, Tuesday the 18th stays clean but the swell is up to 7ft, which is pushing it for the average surfer, and the wind is moderate cross-off. From Wednesday the 19th onwards, conditions deteriorate with onshore winds and poor surf all the way through to Friday the 21st of August.

Overall, the first standout is definitely Saturday morning, 8th of August, with that offshore wind and solid 8ft SW swell for the crew who can handle it. The second standout is that beautiful glassy stretch on Sunday the 16th of August – 5ft to 5ft, clean as a whistle, perfect for a long session. Crowds are possible here sometimes, so get there early.
