Onrus Surf Forecast and Surf Report

Alright, grab your wettie, let’s talk about the next couple of weeks at Onrus. We’ve got a wild ride ahead, but it’s not all smooth sailing.

Right off the bat, Wednesday morning at Onrus is looking massive but clean. Swell is pumping at a solid 9.8ft from the southwest, with a long 13-second period, and it’s glassy—barely a breath of wind. The water’s sitting at 59°, which is just about average for this time of year. But here’s the thing: this is a reef break, inconsistent at the best of times, and 9.8ft is a lot of ocean. This is strictly for experienced surfers only. The energy is off the charts at 2802, so expect serious power. It’s a standout if you’ve got the chops and you’re willing to sit out the crowds that are sometimes around.

Wednesday afternoon the wind swings and the quality drops fast—cross-onshore and messy. Don’t bother. The rest of the week is a write-off. Thursday and Friday have onshore gales and poor conditions, with swell bouncing around but nothing worth paddling out for. The weekend is just as grim, with strong cross-offshore winds and choppy, blown-out surf. The first week is basically a bust after that one glassy window.

Now, look ahead to Monday, the 7th of September. That’s your next real chance. Monday morning brings clean, cross-offshore winds from the WNW, with a 5.2ft SW swell at 14 seconds. The energy is a healthy 1049, and conditions are described as excellent for experienced surfers. It’s not the biggest, but it’s rideable and clean—sometimes that’s all you need. Still, remember this spot is inconsistent, so don’t bank on perfect sets rolling through.

The middle of the second week is quiet, with small, clean waves on the 8th and 9th, but they’re tiny—2.3ft to 3.0ft. Fun for a longboard if you’re desperate, but nothing to write home about. The standout in the second week is Thursday the 10th of September. Morning glass again, 5.6ft from the WSW at 11 seconds, very clean conditions, and a good energy reading of 627. That’s a lovely window for a solid session on a reef that can handle a bit of size.

But hold on—the real monster shows up on the 16th of September. Wednesday morning has a 7.9ft SW swell, 10-second period, cross-offshore wind, and the energy has jumped to 2954. That’s expert territory again. By the afternoon, it’s even bigger: 13.1ft from the SW with a very long 16-second period, and the combined energy is a staggering 9294. That’s massive, deep-water energy. However, it’s predicted to be too big for this break, and with an onshore wind by then, it’ll be a washing machine. Only the bravest (and biggest) chargers should even think about it.

The best on offer: Wednesday morning (2nd of September) for the brave, glassy 9.8ft peak, and Thursday morning (10th of September) for a cleaner, more manageable 5.6ft session. The 16th of September is a wildcard—huge, but likely unruly.

Stay safe out there.
