Kadu Surf Forecast and Surf Report

Alright, mates, Rusty here. Let’s talk about the next couple of weeks. We’ve got a proper run of surf on the cards, but it’s not all gonna be firing. The real juice is up front and then again right at the end of the window. The first couple of days are the standout, no question. After that, we’ll be scraping for a few decent waves before another push of energy shows up around the start of September.

We kick things off proper on Tuesday the 18th of August. Kadu (Big Island) is going to be the place to be. We’re looking at a solid 6ft to 7ft of SSW swell with a long 18 second period. That’s proper groundswell energy, and the combined swell energy is strong, reading 2355 and then 2499. It’s a lot of water moving. The wind is a light cross-offshore breeze at 6 mph, keeping it glassy and clean. This is excellent, experienced surfer territory. The water temp is about average for this time of year, so nothing wild there. This is the pick of the week, no doubt. It’s a reef break and fairly consistent, so be ready. Crowds are sometimes a factor, so pick your moment.

Wednesday the 19th is still good, but a step down. Swell drops to 5ft and the period eases to 16 seconds. It’s still clean with that light cross-off wind, and the energy is moderate at 1837 in the morning. Still a great day for it.

Then we’ve got a bit of a lull. Thursday the 20th and Friday the 21st see the swell dropping right off. We’re down to under three feet on Friday morning with a period of 14 seconds, and the energy is weak, reading just 447. It’s still clean but there’s just not much push. Saturday and Sunday the 22nd and 23rd are similar – small, short-period leftovers in the 3ft range. The energy is weak, down in the low hundreds. It’s surfable for a log but nothing to get excited about. This stretch is really about patience.

We stay in this funk for a few more days. Monday the 24th through Thursday the 27th of August are all pretty marginal. Swell heights hover around 2ft to 4ft, with periods that are all over the place. The wind stays light and offshore for the most part, so the surface is clean, but the ocean just doesn’t have any muscle. The energy readings are consistently weak, often below 500. There’s a little bump on Wednesday the 26th with 4ft of SSW swell and a 15 second period, but it’s not enough to call it good.

Now, here’s where things start to get interesting again. Friday the 28th sees a new pulse of SW swell arrive. The morning is a bit scratchy with a cross-shore wind, but the afternoon cleans right up. We’re looking at 5ft of SW swell with a 16 second period and combined energy of 1797. The winds turn light cross-off, making for clean conditions. This is a solid afternoon session.

Saturday the 29th of August is looking like the second standout of the whole stretch. We’ve got a light cross-off breeze all day, with 4ft of swell that has a very long 19 second period in the afternoon. The energy is strong at 1739, and the conditions are clean. It’s a bit smaller than Tuesday but the quality is there. This one is promising, though being a week and a half out, you gotta keep an eye on it.

Sunday the 30th and Monday the 31st bring a bit more size, but it’s not as clean. We’re looking at 6ft to 7ft of SSW to S swell, with periods around 16-19 seconds. The energy is strong, reading 1772 and then 2390. This is big, powerful swell, likely too big for beginners. It’s for the experienced crew only. The winds are still offshore but a bit stronger, and the wave comment calls it marginal, likely due to the size and power making conditions challenging.

We’ll finish up with a bit of a fade into Tuesday the 1st and Wednesday the 2nd of September. Still some S swell around the 4ft to 4ft mark with a 15-16 second period. The energy is moderate. Wednesday morning looks like it might have a little more shape with a 3ft S swell but a long 18 second period. It’s cleaner but smaller.

So, to keep it simple: get after it on Tuesday the 18th and Saturday the 29th. Those are your two best bets. The middle part of the period is a waiting game.

Rusty, out.
