The Lowdown
Alright, listen up. It’s Rusty here, looking at the next stretch for Tawharanui. I gotta be straight with you: it’s a pretty flat and quiet run for a good while. The swell window is tiny, and the energy just isn't there.
We’re looking at a whole run of days where the surf is just not happening. The size barely gets past a ripple for the first week and a half or so. You'll see some clean conditions with offshore winds, especially around the 12th and 13th when the southwest wind is blowing, but there’s just nothing to ride. A clean flat ocean is still a flat ocean, and you’ll be doing more floating than surfing. The energy readings are weak, down in the single digits and teens (9 to 53). It’s just a waiting game.
The water temp is right around 58.8°F, which is pretty much spot-on average for this time of year, so no surprises there in the first few days.
Now, the models are showing a bit of a pulse trying to build in around the 22nd. We start to see some size come up, with the swell reading around 2ft, and the energy numbers finally getting into the triple digits (101 to 157). It’s still not huge, but it’s the biggest we’ve seen. This looks like it’s lining up for the 23rd, with a NNE swell. But here’s the rub, the wind is looking like it’ll be onshore and a bit choppy that day, which will mess up the shape.
The standout window looks like the morning of the 24th of September. The swell is still there at 2ft, the wind goes light and offshore, and the conditions should clean right up. It’s not a day for heroes, but if you’re keen, it’s the best chance to get a few crumbly ones at Tawharanui (Auckland). The swell direction is NE, which is the optimum for this break, so it should be holding some shape. It’s a beach and reef setup, so it can handle a few different angles.
Honestly, if you’re a beginner, these small waves are still fine, but there might not be enough push. If you’re more experienced, you’ll be looking for that Thursday morning session.
So, in short, don’t hold your breath for the next week and a half. The surf is essentially flat. The first real chance of a wave comes on the 23rd, but it’ll be rough. The only true standout is the clean, small morning on the 24th. Keep an eye on it, but for a long-range call, it’s promising but I wouldn't bet the farm on it just yet. The surf looks more interesting for paddle surfing than trying to get the kite out, though. That’s about it from me. Keep the faith.

Information about the Tawharanui Surf forecast
The above surf forecast table for Tawharanui provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Tawharanui can be found by selecting the local surf guide option on the grey menu. Our Tawharanui 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 (Tawharanui) 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 Tawharanui 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.
Tawharanui is 48 km (30 miles) from the city of Northshore. If you plan a holiday in Northland, look for hotels and other accommodation in Northshore. Northshore has rooms for a wide range of budgets as well as car hire and transport links.
