Waimea Rivermouth Surf Forecast and Surf Report

Alright folks, Rusty here. Let's have a look at what's on the table for Waimea Rivermouth over the next couple of weeks.

We've got a bit of a mixed bag coming up. The first few days look a little messy, but the middle of the week is shaping up real nice, and there's some interesting stuff further out, though that's a bit more of a gamble.

The action kicks off Friday, July 31st, but it's nothing to write home about. We're looking at a 5 ft to 7 ft east swell, with a short period of 7 seconds, and a cross-off wind. The energy is moderate (522-656), but the conditions are just marginal. Saturday the 1st of August starts with a similar story, a 8 ft east swell and a cross-off, but the energy picks up a bit (869). Then it just drops off to a tiny 1 ft south swell in the afternoon. Not great.

Sunday the 2nd is where things start to look up. The morning sees a clean 7 ft east swell with an 8-second period, cross-off winds, and the conditions are expected to be very good. The energy is solid (582). If you're a beginner, that 7 ft might be a bit of a handful, but it's a decent wave.

But the real standout, the one you want to circle on the calendar, is Tuesday the 4th of August. The morning is showing a 4 ft east swell, but the period jumps to 12 seconds – that's proper groundswell. And the wind? Glassy. Absolutely glassy. The energy is strong (536) and the conditions are expected to be very good. Afternoon is just as sweet, with a 5 ft east swell, 11-second period, and more glassy conditions. This is the pick of the whole forecast. The water temp is about average for the time of year, so no surprises there.

After that, it gets a bit quiet again from the 5th through to the 7th, with tiny 1 ft south swells and ordinary conditions. That's a solid three-day gap with not much to offer.

We get a little pulse back on the weekend of the 8th and 9th, with chest-high east swell showing up. The morning of Sunday the 9th looks best with a 6 ft east swell, a 7-second period, but the energy is strong (761) and the conditions are very good. It's a shorter-period swell, so it'll be a bit more walled up, but still fun.

Looking further out, the second week has a promising run from the 10th to the 12th of August. The 10th has a mix of a small 3 ft SSW groundswell (16 seconds) and a bigger 3 ft S swell on the afternoon. The energy is strong (846-903) and the conditions are very good, but that long-period south swell is a bit of a caveat – it can be a bit too straight for a beach break setup. The 11th and 12th keep that clean, chest-high south swell running with good energy. There's even an 18-second period showing on the 12th afternoon, which is incredibly long, but again, it might not be the best shape for the Rivermouth itself.

The very end of the run, the 14th and 15th, gets a bit choppy as the wind turns onshore and cross-shore, so you can probably give those a miss.

Best Bet: Tuesday the 4th of August. Small but clean, glassy conditions, and proper groundswell. That's your day.

Also Worth A Look: Sunday the 2nd and Sunday the 9th of August, especially the mornings for cleaner conditions.

Stay keen, catch some waves.
