The Lowdown
Alright, gather 'round. Rusty here. Let's have a look at what's on the table for the Waipaoa River. This is a stretch that needs the stars to align just right, and for much of this outlook, we're waiting for that alignment. It's a spot for the advanced crew, and it can be a bit hit-and-miss with the consistency, so we're not talking about a daily bank job here.
The water's sitting at 55°, which is a bit colder than normal for this time of year. You'll want a good hood and gloves for sure if you're in the water on the 14th.
The forecast starts with a bit of a tease. Monday afternoon the 14th brings a 4ft SSE swell, but the energy is moderate (609) and conditions are described as marginal. The wind is light from the ESE, but the tide or setup just isn't cooperating. Tuesday stays small, maybe knee-to-waist high at best. We're essentially in a waiting game through the middle of the week with small, less-than-ideal waves.
There's a real gap in quality here. The first real standout doesn't roll around until Saturday morning the 19th. That morning we see a clean 5ft SE swell with a decent 11-second period, offshore and cross-off winds from the NW, and a light breeze keeping it tidy. The energy is solid (584). This is your best bet in the near term. The water might have warmed a touch by then, but it's still going to be brisk.
The second week gets a little more interesting, but also carries a big red flag. On Wednesday the 23rd, we see a massive 10ft SSW swell roll in, but the model is telling us point-blank: it's too big for this break. The energy is extreme (2815). That goes for Thursday the 24th as well, with 12ft and 10ft S swells, also too big. This is dangerous territory, strictly for the kamikaze crew or those with a death wish.
After that big pulse, things mellow out. The real highlight might just be right at the very end of the forecast, on Tuesday morning the 29th. We have a 4ft SSE groundswell with a very long 15-second period, and the wind is completely glassy (0 mph, from the NNE). The energy is building (739). That's a recipe for the cleanest, most lined-up waves you'll get on this river mouth. With that long-period groundswell, sets will be well-spaced, making the paddle out a little easier for the advanced surfers here. Keep in mind, crowds are possible at this spot, and with a standout like that, expect a few others to have the same idea. The afternoon before, Sunday morning the 27th, is also a strong runner-up with a clean 5ft ESE swell and light NW winds.
To sum it up: we've got some small, ordinary days, a couple of days that are genuinely dangerous due to size, and then two really sweet windows of clean, quality surf. Focus on Saturday the 19th morning and Sunday morning the 27th, with Tuesday morning the 29th being the absolute pick of the litter if you can wait for it.

Information about the Waipaoa River Surf forecast
The above surf forecast table for Waipaoa River provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Waipaoa River can be found by selecting the local surf guide option on the grey menu. Our Waipaoa River surf forecast is unique since it includes wave energy (power) that defines the real feel of the surf rather than just the height or the period. If you surf the same spot (Waipaoa River) regularly then make a mental note of the wave energy from the surf forecast table each time you go. Very soon you may start to choose your surf days based on the wave energy alone combined with our forecast of favourable offshore wind conditions. Our star ratings will help here and of course you will also find the usual wave height and period predictions on our surf forecasts as well as a full break down of the swell components under our advanced users option (to reveal that, click the little Einstein character under the tide times).
Further information to help with frequently asked questions about our surf forecast for Waipaoa River may be found under the help tab on the top menu and also by moving your mouse over the question marks on the surf forecast table itself. Please always bear in mind that the forecast is for near-shore open water and local factors at each surf break influence the actual breaking wave height, such as the beach / reef profile, water depths offshore and shelter.
