Keaau Surf Forecast and Surf Report

G'day, I'm Rusty. Let's have a look at what's on the menu for the next couple of weeks. Keaau is a beach and reef setup that's exposed and consistent, so it's usually in the mix. Right now, the water temp is sitting around average for the time of year, so nothing wild there.

The word for the first week is... ordinary. The forecast starts quiet, real quiet. Saturday the 29th is a total write-off for surfing, with a tiny 0.7ft swell from the west and barely any energy (9). Sunday the 30th rolls in with a bit more life – a 4ft north-east swell, but with a short period of 7 seconds, it's pretty weak and won't have much shape. The wind is offshore and clean, which is a solid positive, but the overall energy is still low (121). This pattern basically holds through Monday, Tuesday, and Wednesday: small swell around 4ft to 4ft, short period, and while the wind stays offshore, the waves are just not doing much. The energy is moderate at best, peaking around 174 on Tuesday afternoon, but the surf quality is poor. Thursday the 3rd sees things drop off again, with the swell fading to 3ft, and by Friday the 4th it's back to 0.7ft to 3ft. There's a real gap here from the 31st through to the 6th of September where it's nothing but small, weak, and ordinary surf. Not worth getting excited about.

Now, there's a bit of a shift on the 7th of September. Monday morning brings a 4ft north-east swell with a bit more energy (186), but the wind is strong at 25 km/h and the surf is still described as poor. The 8th of September is the first real standout in the run. Tuesday afternoon sees the swell bump up to 5ft from the north-east, with a period of 8 seconds and moderate energy (297). The wind is a moderate offshore from the east-north-east, so the conditions are clean. The guidance rates this spot as intermediate, consistent, and sometimes crowded, so expect some company. This is the best window we've had so far.

But the real headline act is a long-range pulse coming in around the 11th of September. Friday the 11th morning sees a 3ft swell from the west, but with a very long period of 16 seconds and strong energy (639). That's a big groundswell. The wind is light cross-onshore, so it's not perfect, but the energy is significant. The afternoon pushes to 4ft from the west, with an 18-second period and a massive 940 energy reading. This is a serious swell for a beach and reef break. The caveat with a long-period groundswell like this is that it can break a bit too straight on a beach, but Keaau's reef structure should handle it nicely. This is a standout for the more experienced crew. The following Saturday the 12th stays solid with 4ft to 4ft, similar long period, but the wind turns onshore, so it's not quite as clean. The 13th of September sees the energy drop to 486, still a 3ft west swell with a 14-second period, which is still a good wave.

So, if you're looking for the pick of the litter, hit Tuesday the 8th of September afternoon for a clean, solid 5ft north-east swell. The real stand-out for the crew who can handle bigger energy is Friday the 11th of September, with that massive west groundswell. It's a long-range call, so less certain, but it's got all the makings of a ripper.

Rusty.
