Onrus Surf Forecast and Surf Report

Alright, Rusty here. Let's talk about what's coming up for our little corner of the coast. The swell window is looking a bit mixed, so we’ll have to be patient and pick our moments.

We’ve got a few small pulses of energy, but nothing massive or long-lasting right off the bat. The water temp is sitting at about 59°, which is a touch below the norm for this time of year – nothing crazy, just a reminder it's still winter.

The standout window is Thursday, August 27th. We’ve got a clean 5ft groundswell pushing in from the south-southwest, with an 11-second period. The real story that day is the wind: glassy, dead calm conditions both morning and afternoon. It’s going to be smooth, clean, and the reef at Onrus will offer up some nice, workable lines. The combined energy is decent, sitting at 688 (moderate), but the lack of wind chop will make it feel much better than the numbers suggest. Crowds are a possibility here, so get out early.

Saturday, August 29th, is another one to circle. We’re looking at 5ft swell from the west-southwest, 13-second period, and glassy conditions again in the morning. The energy picks up a bit to 884. The afternoon sees a bit of a bump to 5ft with a clean cross-off breeze – still good, but the morning glass-off will be the premium session.

Now, a word of caution about the first week of September. Around the 1st and 2nd, a big, powerful SW groundswell moves in, hitting 10ft to 12ft. The period is long at 14 seconds, with massive energy readings over 3000 and even 4000. This is expert territory only. While the wind is offshore and clean on Tuesday afternoon and Wednesday morning, this much water moving over the reef at Onrus will be heavy, challenging, and likely shut down for most. This is more of a tow or big-wave crew slot, if it's even makeable.

After that big pulse, the following week from the 3rd to the 6th of September gets messy. Strong cross-onshore winds and lumpy conditions dominate, with 7ft to 12ft of wind-affected chop. Honestly, it’s going to look more interesting for kite surfing than a clean paddle session for most of those days.

The real sleeper hit comes right at the tail end of the forecast. Monday, September 7th afternoon looks absolutely world-class for the right crew. We’ve got 4ft of groundswell from the southwest with a very long 15-second period. The combined energy is moderate at 1088, but the period is the story. It’s glassy, dead calm, and that long-period SW swell will wrap in beautifully. This is a reef break, so a long period groundswell like that is ideal – it will handle the shape perfectly. The energy will be substantial, the lines will be clean, and the paddle-out easy between sets. It’s a full week and a half out, so keep a close eye on it, but right now it’s the one to dream on.

Bottom line: hit Thursday the 27th, Saturday the 29th, and keep a very close watch on the 7th of September. Everything else is either too small, too messy, or too big for a fun, relaxing session.

Rusty.
