Onrus Surf Forecast and Surf Report

Alright, Rusty here with a look at Onrus for the next couple of weeks.

The first few days have some clean, rideable waves, but nothing huge. Friday July 3rd starts with a solid W swell around 6ft, period 8 seconds, and northwest winds blowing offshore. Water temp is 59°, right about normal for this time of year. The combined energy is moderate (714). This spot can be a little inconsistent, but for a Friday morning, you'll find some fun ones.

Saturday July 4th sees the swell drop way down to around 2ft, but that southwest groundswell has a gorgeous long period of 16 seconds – proper energy for a reef. Saturday afternoon is the standout of the early days: 2ft of SW groundswell at 15 seconds, with WNW offshore wind. Combined energy (504) is moderate, but quality will be high with light wind keeping it clean. Crowds are possible here.

Sunday July 5th keeps the small SW groundswell going in the morning, then afternoon brings a new 5ft W swell with 9-second period and energy of 741. Still light winds. Good afternoon.

Monday July 6th and Tuesday July 7th see the swell build. Monday is messy with cross-shore wind and 8ft swell. Not worth it. But Tuesday July 7th – that’s your real highlight. Morning and afternoon are glassy, with a 7ft SW groundswell at a solid 12 seconds. The energy is strong (1157), and conditions are excellent for experienced surfers. Over 8ft might be too much for beginners, but for anyone with skill, this is the best session of the first week. Onrus (South Africa) is a reef, and that long-period SW groundswell will wrap in nicely. Glassy and clean.

After Tuesday, the wind goes ugly. Wednesday July 8th through Friday July 10th has easterly cross-on winds and big swell (8ft to 8ft), but quality is poor – choppy and bumpy. Energy is very high (over 2400 at times), but with the wind messing it up, it’s more for kite surfing than paddling. Not recommended.

Saturday July 11th and Sunday July 12th drop in size, but cross-on winds linger. Marginal quality. A blank run from the 8th through the 13th for decent surf.

Monday July 13th and Tuesday July 14th are small and windy. Onrus goes quiet.

Then Wednesday July 15th onward the ocean goes crazy – 13ft+ SW swells with very strong energy (over 4400). But forecasts say it’s simply too big for this break. Onrus can’t handle it, so it’s a pass, even if winds look light. That runs through Friday July 17th.

Finally, Saturday July 18th shows promise again: 8ft S groundswell, 12 seconds, with WNW cross-offshore winds. Clean conditions, combined energy 1926 – strong but manageable. That’s another good day for experienced surfers. Saturday afternoon stays solid at 7ft and clean.

Bottom line: Tuesday July 7th is the standout – glassy, 7ft SW groundswell, strong energy, and clean. If you can wait, Saturday July 18th is also well worth a look for experienced surfers with a good S swell and offshore winds.
