Waimea Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here with the full outlook for the upcoming stretch.

We’re looking at a solid run of clean, user-friendly surf at Waimea Rivermouth starting this Wednesday afternoon. The water temp is sitting around 81°, which is pretty average for this time of year, so nothing unusual there. The standout window kicks off Wednesday the 26th through the end of the month, with a nice mix of long-period southerly groundswell and light cross-off winds that’ll keep the waves tidy. The combined energy reading of 629 (moderate) on Wednesday hints at some decent push.

The best of the first wave is Thursday the 27th, with 3ft of swell from the south at a long 17-second period, making for a smooth, clean face. The wind stays light and cross-off, so don’t expect much chop. This is a great spot for beginners, and the crowd factor is only “sometimes” an issue, so you’ve got a good chance at a peak to yourself.

As we roll into the weekend, the swell direction shifts more east and the period drops to 7 seconds, but the energy stays moderate (around 363-510). Saturday the 29th afternoon sees swell bumping up to 6ft, which is still manageable for most, but the wind picks up a notch. The real highlight is Sunday the 30th morning, where the energy climbs to 510 (moderate) and the swell is 5ft from the east – still clean and cross-off.

Monday the 31st holds similar size at 5-6ft, but keep an eye out for rain showers. Nothing that’ll ruin the waves, though.

After a brief dip on Tuesday the 1st of September, we get a spike in energy to 835 (moderate-strong) on Tuesday afternoon, with 6ft east swell at 9 seconds. That’s a punchy, fun option but the wind is slightly stronger, so it won’t be as glassy as earlier in the week.

The second week gets a bit mixed. Wednesday the 2nd has a smaller south swell return, and Thursday the 3rd sees glassy conditions with 2ft from the south and a glassy offshore wind. That’s a clean, smaller window. Friday the 4th offers glassy morning surf with 3ft south swell, then the weekend brings a ramping east swell with glassy conditions on Saturday the 5th afternoon – 5ft east swell, glassy, energy of 604 (moderate). That’s a real sleeper standout for the second week, but it’s a bit further out so keep an eye on the forecasts.

After that, the run fades. Sunday the 6th and Monday the 7th look choppy and cross-onshore, so not worth paddling out. Tuesday the 8th morning is marginal, but the afternoon cleans up again with a light cross-off and 3ft south-southwest swell. The last real window looks to be Wednesday the 9th morning with glassy 2ft south-southwest swell, then Thursday the 10th afternoon brings a new east swell at 4ft, long period of 12 seconds, and very clean conditions – energy of 551 (moderate). That’s a promising note to end on, but it’s a long way out.

Overall, for the beginner-friendly crowd, the first week is your best bet. The standout is Thursday the 27th morning, with clean 3ft south swell and glassy winds. If you’re okay with a little more size, Sunday the 30th morning is also a ripper.

Rusty.
