Haumoana River Mouth Surf Forecast and Surf Report

Righto, let’s have a look at what’s comin’ down the line for the coming weeks. It’s a bit of a slow start, I won’t lie. The first few days aren’t worth gettin’ wet for—tiny, weak, and messy. But hold onto your leash, ’cause there’s a proper pulse of energy buildin’ later on that’ll have the river mouth talkin’.

We’re talkin’ Haumoana River Mouth, a river bar setup that’s got a bit of a reputation. It’s advanced-only, fairly consistent when it’s on, but it needs that swell from the NE direction to really fire. The water temp is sittin’ around 55°F, which is a bit colder than normal for this time of year—about 2 degrees below average, so you’ll want the rubber on.

The first real sign of life shows up on Sunday the 26th of July. The morning’s still pretty ordinary with surfable but weak waves, but by the afternoon, things start to flicker. Swell bumps up to 2ft from the ESE, period stretchin’ to 14 seconds, and the combined energy hits 295 (moderate). The wind’s a clean cross-off from the SSW, and the wave comment says expect good surf. It’s still not huge, but it’s clean and there’s a hint of what’s to come.

Now, the standout—and I mean the real standout—is Monday the 27th of July. This is the one you’ve been waiting for. The morning serves up 5ft of ESE swell with a 13-second period, and the combined energy is a solid 632 (strong). The wind is slight air, cross-off from the NW, makin’ it basically glassy. The wave comment says expect very good surf conditions. By the afternoon, it’s even better: 5ft, same direction, 13-second period, and the energy jumps to 755 (strong). Wind’s a gentle cross-off from the WNW. The waves are gonna be clean, lined up, and punchy for a river bar. This is the pick of the entire forecast. Swell’s a bit over 5ft, so it’s not for beginners, but for the advanced crew, it’s a treat. The period’s over 11 seconds, so it’s groundswell, and on a river bar that can handle it, the shape should be real good.

Tuesday the 28th of July is still solid in the morning, with 4ft from the ESE, 13 seconds, and 484 energy (moderate). Offshore wind from the SW, clean. The afternoon turns a bit messy with cross-on wind, so get your session in early.

From Wednesday the 29th through to the end of the first week of August, the waves drop back into the 2ft to 3ft range, still from the ESE, with periods hangin’ around 11 to 13 seconds. The energy is moderate to weak. The mornings stay clean with cross-off winds, but afternoons get a bit mixed. There’s a few good windows in there—Wednesday the 29th afternoon and Thursday the 30th morning both have good surf conditions with light winds, but the size is down. Crowds are possible at this spot sometimes, so if you’re after a quieter paddle, the smaller days might be your best bet.

The second week is a bit of a mixed bag. Sunday the 2nd of August afternoon has a pulse of 2ft from the SE with 13 seconds and 250 energy (moderate), and clean cross-off wind. Then Monday the 3rd of August morning has a moderate offshore breeze from the SW, 3ft from the ESE, 11 seconds, and 264 energy (moderate)—good, clean conditions. The rest of the week tails off into small, weak surf with poor conditions.

Overall, the best on offer is absolutely Monday the 27th of July. That’s the call. If you can only paddle out once, make it that day. The river mouth’ll be firing with clean, solid waves and just enough energy to make it memorable. The rest of the time, you’ll be pickin’ the clean morning windows for a fun, smaller session.
