Alright folks, Rusty here. Let’s break down what’s on the menu for this stretch.

It’s a slow start, no doubt about it. The first several days are a total ghost town for surf. Don’t even bother checking the tide charts. The action doesn’t show up until late in the week.

For Right and Left Side, the water is sitting at 84°F, which is pretty much standard for this time of year – nothing unusual.

The first real sign of life comes on Friday, 24 July, morning. We’re looking at a clean 4ft swell from the west, with a 9-second period. The wind is light and cross-offshore, making for some clean, workable waves. The combined energy is moderate at 214. It’s not a day for heroics, but it’s a solid session.

Now, the absolute standout is Saturday, 25 July. That morning, the swell pushes up to 5ft from the west, with a 10-second period, and the wind is light and offshore – glassy, clean, perfect. The energy is a solid 400. The afternoon stays strong too, with 4ft from the west and light offshore wind, energy at 319. This is the day to clear your calendar. The waves will have some punch, and the offshore wind will keep them looking sharp. Keep in mind, this spot can get crowded sometimes, but for quality like this, it’s worth sharing the lineup.

Before that, on Thursday, 23 July, there’s a pulse of 5ft from the west with an 8-second period, and clean cross-offshore wind. The energy is 383, but the quality isn’t there – it’s one of those days with size but no shape.

After Saturday’s peak, it fades out fast. Sunday the 26th has some small clean waves, but nothing to rave about. The following Monday and Tuesday are back to weak, small, and cross-offshore – not worth the effort.

So here’s the deal: the first week is a bust. The window cracks open on the 24th, peaks on the 25th, and then closes. If you can only surf one day, make it Saturday, 25 July.

Rusty.

Further information to help with frequently asked questions about our surf forecast for Right and Left Side may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself.
