Waimea Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a look at what’s coming down the line for this spot.

We’ve got a run of surf starting right away on Tuesday, September 1st, and it’s going to be a bit of a mixed bag. The first few days are looking pretty fun, but things get a little more interesting as we head into the weekend.

The standout period is definitely from Saturday, September 5th, through to Monday, September 7th. Saturday afternoon kicks off a superb window with a solid 6ft swell from the east, a long period of 13 seconds, and light winds. That’s proper groundswell energy rolling in, with the combined energy hitting a hefty 1906 (strong wave energy). The water temp is about average for this time of year, so no worries there.

Sunday, September 6th, is the real gem. The whole day is firing. We’ve got 6ft of east swell, still with that 13-second period, and the combined energy is even higher at 2109 (strong wave energy). The wind is a light breeze from the east, keeping things clean. This is the best on offer – a classic setup for this river mouth. The swell direction matches the optimum (S), so it’s going to be a great shape. Just keep in mind this spot is a beginner-friendly break and can get crowded sometimes, so get out early.

The runs from Tuesday to Friday are a bit of a mix. Tuesday afternoon has a small 2ft swell from the south-southwest with a very long 18-second period, but the energy is a moderate 379. The wind is a light cross-off, so it’ll be clean. Wednesday morning is similar with a 3ft south swell (16 seconds) and 446 energy. Wednesday afternoon and Thursday see the swell bump up to 6ft from the east, but with a shorter 8-second period, though the energy is moderate to strong (759 and 738). It’s all clean, but the shorter period might make it a bit less consistent.

After that Monday peak, the surf eases down. From Tuesday, September 8th, the conditions get a bit cross-choppy, and the swell drops. There’s a significant gap from around Thursday, September 10th, afternoon through to the end of the forecast. The waves get tiny, with a few glassy mornings but very little energy, like on Saturday, September 12th, and Sunday, 13th, where the combined energy is only 65 to 99 (weak wave energy). It’s a real lull, so don’t expect much action in the second week. The swells are small and short-period, and the energy just isn’t there.

So, to sum it up: get on it this weekend and the start of the following week. The best window is definitely Saturday, September 5th, through to Monday, September 7th. Don’t waste it.

Rusty.
