Onrus Surf Forecast and Surf Report

Alright, let's look at this Onrus forecast for the next couple of weeks. It's a reef break, intermediate level, exposed to the southwest, but it's inconsistent, so patience is key. Crowds can roll through sometimes.

Water temp is about 15°, which is nearly 2° colder than the normal for this time of year. That's a noticeable chill.

This starts on Saturday, the 12th, and is basically a no-go through to Monday morning the 14th. There's a big south-west groundswell with a mighty energy rating (1774), but the south-east wind is screaming at 15 mph, blowing right across the swell, turning it into a choppy, lumpy mess. Not worth a look.

Monday the 14th is the first flicker of life. The wind switches to the northwest, going offshore. The swell drops to a marginal 4ft, with a 12-second period. The energy is moderate (481). The size is tiny, the wind is fresh, and it's a reef. You might snag a couple of clean little ones, but it's not worth the drive. Tuesday the 15th is a tricky one. The wind is offshore again, strong at 25 mph. The morning swell is 6ft, but the period is a short, chunky 6 seconds (612 energy). That's windswell and will be bumpy. The afternoon brings a 5ft groundswell with a long 16-second period (1598 energy). That kind of long-period swell on a reef at that size is expert territory. The strong offshore wind will make take-offs extremely critical. If you're not a solid intermediate, sit this one out.

Wednesday the 16th and Thursday the 17th are back to poor, onshore conditions with the south-easter returning and messing up a 6ft+ swell. This poor run continues through to the 19th.

Now, the big standout. Circle Sunday the 20th of September. The morning is perfection. The wind drops to almost nothing, described as glassy. The swell is a clean 5ft from the southwest with a 13-second period (710 energy). The energy is moderate. Getting glassy conditions on an exposed reef like Onrus with a solid, long-period swell is a total score. The water will be like a mirror. It will be a flawless, clean, paddable wave. For intermediates, this is your absolute window. The afternoon picks up a light cross-on breeze, so get on it early.

The next week stays mostly poor until Thursday the 24th. That morning looks very clean. A gentle west-north-west breeze, clean conditions, and a 5ft SW groundswell (1313 energy). The wind is cross-off, keeping the face clean. This is a solid, mellow option for experienced surfers.

Finally, the long-range gem. On Sunday the 27th, another big pulse is forecast. A 6ft to 7ft SW groundswell with a massive 18-second period (2277 to 2796 energy). That's a huge, powerful groundswell. The wind is light to gentle and cross-off. This is a recipe for a big, heavy, immaculate day. This one is strictly for the experts. The size is over 5ft, so beginners sit on the beach. The long period means the sets will be spaced, but very powerful. Over 8ft, it's expert-only, and the afternoon gets close to that. If you've got the skills, this could be the session of the month, but it's over a week away, so keep a close eye on the models.

Overall, the first week is mostly garbage. The absolute best bets are that glassy Sunday morning on the 20th for everyone, and that big, clean Sunday on the 27th for the pros.
