Onrus Surf Forecast and Surf Report

Alright, folks, Rusty here. Let’s get into it.

We’ve got a 16-day window for Onrus, a reef setup that’s exposed to the SW. The water temp is sitting at about 59°F, which is a touch cooler than usual for this time of year – nothing wild, but you’ll feel it. The first week is a bit of a write-off, but there’s a couple of promising windows if you’re patient.

The first few days are a slog. The swell is solid enough, with 8ft to 7ft SW swell, but the wind is all cross-on from the east, making things choppy and lumpy. The combined swell energy is moderate to strong (values between 1143 and 2644), but it’s not clean. The scores are low, and honestly, it’s not worth the paddle.

We get a brief reprieve on the morning of Tuesday, 14 July. The wind goes glassy – a light NW at 3 mph – and the swell drops to 2ft from the west, period 10 seconds. The combined energy is weak (217), but it’s clean. This is a tiny, glassy option for a longboard or a foamie, but it’s not going to fire.

Wednesday, 15 July afternoon sees a spike in energy. The wind shifts to a clean cross-off from the west at 12 mph, and the swell jumps to 4ft from the SW with a very long period of 18 seconds. This is a groundswell. The combined energy goes moderate (1248). It’s just a marginal call, but the clean conditions and the long period could make for some fun, organised lines on the reef. It’s a looker, but not a standout.

Now, the real standout comes on the morning of Thursday, 16 July. The swell pumps up to 12ft from the SW with a 14-second period. The combined energy is strong (4293). The catch is the wind is cross-on from the SSE at 12 mph, making it choppy. And the swell is predicted to be too big for this break. This is big, powerful, and dangerous. Experts only, and even then, it’s a gamble. The afternoon is a no-go with onshore winds.

The next big moment is on Wednesday, 22 July. The morning already looks good with offshore wind from the WNW at 6 mph, 6ft SW swell at 13 seconds, and a combined energy of 1796. But the afternoon is the highlight: 8ft from the SSW with a very long period of 15 seconds, cross-off wind from the WSW at 6 mph, and a combined energy of 3040. The conditions are described as excellent for experienced surfers. This is the one to circle. The long period groundswell will favour the reef, giving you nice, long, powerful walls. Crowds are possible here, so be ready for a few others with the same idea.

Thursday, 23 July morning is also a gem. The wind goes glassy from the east at 3 mph, with a clean 6ft SW swell at 14 seconds and combined energy of 1220. It’s another excellent session for the experienced crew. The wind drops off later in the day, so make the most of the early.

The forecast beyond that gets a bit messy again. Friday, 24 July has a big 10ft SW swell with a 15-second period and a combined energy of 4674, but the cross-on wind makes it too big and messy for this spot.

Bottom line: The first week is mostly a dud. The real action is on the 22nd and 23rd of July. The 22nd afternoon is the best bet – big, clean, and powerful. The 23rd morning is a close second with glassy conditions. Both are for experienced surfers only. The long period swells will make the reef work.
