Onrus Surf Forecast and Surf Report

Alright, Rusty here, lookin’ at the charts for the next couple of weeks. Let’s get into it.

Right off the bat, we’ve got a slow start. Tuesday afternoon at Onrus is surfable, but it’s pretty ordinary – a little 2ft swell from the west with a weak period and cross-off wind. Not worth getting wet for. The real story kicks off Wednesday morning, the 15th of July. A nice SW groundswell fills in at 4ft with a 17-second period, and we’ve got offshore winds. That’s proper clean surf for the experienced crew. The energy is strong at 1229, and it’s only going to get better.

Wednesday afternoon, the swell jumps to 7ft from the SW, still a long 16-second period, and the wind stays cross-off. The conditions are excellent, but that size is getting into the intermediate-to-expert zone. Thursday morning, the 16th, is the real standout of the first week. We’re looking at a 8ft SW swell with a 13-second period, and the wind is glassy offshore at only 5 km/h. The energy is pumping at 2108, and the water is a pleasant 59°F, which is about average for this time of year. That morning session is going to be magic – clean, powerful, and lined up. A bit too big for beginners, but for the experienced surfer, this is the pick of the bunch. Thursday afternoon stays solid at 7ft with cross-off wind.

Friday the 17th turns ugly with a cross-on breeze and a drop in quality, so skip that. Saturday morning the 18th offers a smaller 3ft S swell with clean offshore wind, but it’s a weaker energy (540), so a nice little novelty wave if you’re desperate. The next real gem comes Sunday morning, the 19th of July – 8ft SW swell with a 12-second period, cross-off wind, and excellent conditions. That’s a solid expert session. Then Monday morning, the 20th, is glassy with a 7ft SW swell, 11-second period. That’s clean, powerful, and a joy to paddle out into.

Now, for the second week, things get huge. From Tuesday the 21st of July all the way through the end of the forecast, the swell is consistently over 12ft and often hits 13ft or more, with energy readings in the thousands (8300+). The wind is often offshore or glassy, so the conditions will be clean, but this is massive, dangerous surf. Onrus is a reef break, and with a 13ft SW swell at 16 seconds, it’s going to be a foaming, heavy beast. Only for the most experienced, big-wave chargers. The standout in this big window is perhaps Saturday the 25th of July – a 13ft WSW swell, 15-second period, and glassy conditions. That’s a proper, serious, clean swell with insane energy (7646). But it’s not a beginner’s game. The rest of the week stays huge, with 12ft to 15ft swell and occasional cross-onshore winds that will make it messy on top of the size. For the average surfer, this is a watch-from-the-cliff week.

Overall, the best on offer is Thursday morning, the 16th of July, with that 8ft glassy swell, followed closely by Sunday morning, the 19th. For the big-wave crew, keep an eye on Saturday the 25th.

Stay safe out there.

Rusty.
