Onrus Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s get into it for Onrus. This is a reef setup that needs a solid SW groundswell and clean conditions to really fire, and we’ve got a bit of a mixed bag over the next two weeks.

The first few days are a write-off, I’m afraid. Tuesday the 25th and Wednesday the 26th are a total mess with strong cross-onshore winds and lumpy, poor surf. You’d be better off staying home. The combined energy is high, 1884 on the 25th, but it’s a waste with that wind.

We start to see a glimmer on Thursday the 27th. A light west wind swings cross-offshore, cleaning up a 5ft SW swell with a decent 12 second period. The water temp is sitting at 59°, which is about average for this time of year. The break is inconsistent, but when it works, it’s a proper reef wave. Thursday morning and afternoon both look good, with a combined energy of 781, dropping to 693. The sets are clean and rideable.

Friday the 28th and Saturday the 29th are marginal. The swell drops and the wind stays on the cross, offering small, weak waves. Not worth paddling out unless you’re desperate for a water session.

Now, here’s the standout. Sunday the 30th is the pick of the early period. Sunday morning is looking glassy as glass with a light SSE breeze, zero wind, and a 7ft SW swell rolling in at 13 seconds. This is excellent surf for experienced surfers, with a combined energy of 1548. It’s a bit on the big side for beginners, but for the crew who know the reef, it’s going to be clean and powerful. Crowds are on the table here, as it’s a well-known spot, so get in early.

Monday the 31st is still good, with a smaller 6ft SW swell and a light cross-offshore wind, giving clean waves again.

Then things get weird. Tuesday the 1st of September and Wednesday the 2nd show a massive pulse of SW swell, hitting 15ft with a combined energy of 6693. The wind is offshore, but the swell is simply too big for this reef. It’s a dangerous, washing-machine scenario. Kite surfers might have a field day, but for paddle surfing, it’s a skip.

Thursday the 3rd of September is another real gem. A glassy, calm morning with a 8ft SW swell at 12 seconds. Excellent conditions for experienced surfers again, with a combined energy of 1792. This is your second standout. The reef will hold this size well and the clean conditions will make for some memorable waves.

After that, the forecast drops off a cliff. Friday the 4th through Sunday the 6th are back to poor conditions with strong cross-onshore winds and tiny, messy surf. The combined energy plummets to 235 on the 5th.

The second week looks quiet but not completely dead. Monday the 7th and Tuesday the 8th offer small, clean waves with a cross-offshore wind, but the swell is tiny, around 3ft to 4ft. It’s a longboard or funboard zone. The Wednesday the 9th shows a little more promise with a clean 3ft SW swell and a 14-second period, giving you some long-period groundswell that will wrap nicely into the reef. It’s a promising but less certain call for the second week.

Overall, the best on offer is hands-down Sunday the 30th morning for the glassy, powerful 7ft swell, and then Thursday the 3rd of September for another glassy, 8ft session. Everything else is either too big, too small, or too windy.

Rusty.
