Waimea Rivermouth Surf Forecast and Surf Report

Hey, Rusty here, breaking down the only game in town for the next couple weeks.

It’s just Waimea Rivermouth on the menu. This is a beginner-friendly spot that breaks fairly often, and it likes the swell coming from the south. Water temp is about what you’d expect for this time of year.

We’re easing into it. Right now, on Wednesday the 29th, it’s tiny but clean. We’re talking a 2ft south swell with a solid 14-second period, and the wind is dead calm – glassy. The energy is moderate. It’s small, but for a longboard, that’s a sweet, clean session. You might have a few mates out there; crowds can be a thing here.

Thursday the 30th stays clean at 3ft, same direction, with a cross-off breeze tidying things up in the afternoon. Friday morning holds clean at 2ft, but the wind gets stronger. Friday afternoon turns into a messy 6ft east windswell (7 seconds) with a cross-chop – that’s not one for the paddle board, looks more like a kite day.

Saturday the 1st of August starts with a bumpy 7ft east swell, then drops to a tiny 2ft southwest groundswell in the afternoon – a skip.

Here’s your first real standout: Sunday the 2nd of August. All day, we get a clean, solid 7ft to 6ft east swell (9 seconds), with a nice cross-off breeze. The energy is strong. It’s a proper wave. A confident beginner can handle it, but at that size it’s getting into intermediate territory.

Monday the 3rd drops to a nicer 5ft east swell, still clean. Then we hit a flat spell. From Tuesday the 4th through Thursday the 6th of August, the ocean goes quiet. Swells are 1ft or less, with very weak energy. The water might be glassy, but there’s nothing to ride. That’s a solid 3-day gap.

Friday the 7th of August brings a short-period 4ft east swell back, clean but not powerful.

Now for the long-range gold. Sunday the 9th of August starts a great run. We’ve got a 3ft to 3ft south-southwest swell with a *very* long period of 17–18 seconds. The energy is strong again. For a rivermouth setup, that long period is perfect – it’ll wrap in with real shape and make for those mellow, lined-up waves. The wind stays clean and offshore through the whole stretch. Wednesday the 12th of August is especially nice with 4ft south swell and glassy conditions.

So the two big calls are Sunday the 2nd of August for a solid, clean east swell, and then the whole stretch from Sunday the 9th to Wednesday the 13th of August for a promising run of quality, long-period groundswell with perfect winds. That second window is a ways off, so don’t book your flight yet, but it’s looking real nice.

Rusty, signing off.
