Waimea Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let’s take a look at what’s cooking for Waimea Rivermouth over the next couple of weeks.

Right off the bat, the first few days are pretty quiet. We’ve got some small, clean surf from Thursday morning (the 10th) through the weekend, but the energy is low and the swells are tiny. Thursday morning is the pick of the early days – a glassy 2ft SSW groundswell with a nice long 13-second period, and the water’s sitting at a warm 80°F, which is about average for this time of year. The combined energy is weak (240), so you’ll be working for every wave, but it’s a good time for beginners or anyone wanting to get wet without any hassle. Expect some company though – crowds are known here sometimes.

Friday morning bumps up a bit with a 4ft E swell, but the period is a short 6 seconds, so it’s a bit crumbly. Still, the wind is light and cross-off, making it clean enough for a session. Saturday and Sunday drop right back down to ankle-snappers again – glassy but barely breaking.

We then hit a real dry spell. Monday the 14th through to Wednesday the 16th is all about those tiny 1ft to 2ft swells. It’s surfable but nothing to write home about. The water is calm, the winds are light and glassy, but you’ll be scratching for a ride.

Now, here’s where it gets interesting. The real standout window starts on Thursday the 17th. Thursday morning brings a nice clean 5ft E swell with a short period (8 seconds) – combined energy is strong at 636 – under a clear sky and a gentle cross-off breeze. It’s a proper fun size for a relaxed paddle. By the afternoon, that swell pushes up to 7ft, which is starting to get a bit beefy for beginners, but fine for anyone with a bit of experience. The cross-off wind keeps it clean.

Friday the 18th and Saturday the 19th are the absolute highlight of this forecast. Friday morning sees a solid 3ft SSW groundswell, but the energy rating is massive at 902 – that’s a lot of power in the water. The wind is a moderate cross-off, so expect clean, punchy lines. The swell direction of SSW is bang on what this spot likes. Saturday is a direct follow-up, still clean and powerful, with a similar 3ft SSW swell and combined energy around 641. This is the best stretch of the whole 16 days – consistent, clean, and with real push.

Sunday the 20th holds some good energy too, with a 5ft E swell in the afternoon that will offer some fun waves, but it’s a short period (8 seconds) again, so a bit less quality than the SSW groundswells.

After that, the energy slowly fades through Monday and Tuesday, with smaller swells and a bit more cross-shore wind chop. The last real standout pops up on Wednesday the 23rd and Thursday the 24th. Wednesday morning brings a glassy 5ft E swell with a 9-second period, and the combined energy is strong at 532. That’s another excellent session with glassy conditions – a real treat for the second week. Thursday morning follows with a solid 3ft SSW groundswell (18-second period) and a combined energy of 812 – very powerful and clean again under a gentle breeze.

So, to wrap it up: the first few days are small but clean, perfect for beginners. The absolute best is the run from Thursday the 17th through to Saturday the 19th, with Friday the 18th being the top pick for power and clean conditions. The second week has another good little window around Wednesday the 23rd.
