The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for Tawharanui.
Honestly, mate, this 16-day stretch is a real struggle. We’ve got a long, flat, wind-affected run staring us in the face, and the few moments where the ocean shows a pulse are let down by messy conditions or just not enough size. The good news is the water temp is sitting about average for this time of year at 57°, so at least it’s not freezing you out while you’re waiting.
The opening week is a write-off. From Thursday the 20th all the way through to Wednesday the 26th, the swell is tiny – mostly 0.3ft to 1ft – and while there are some glassy moments on Wednesday afternoon, there’s just no energy. You’d be scratching for a knee-high ripple. A couple of days with cross-off winds keep it clean, but it’s barely surfable.
Thursday the 27th sees a bit more activity, but that comes with onshore wind and short period windswell. It’s messy and not worth the paddle. Then Friday the 28th – here’s the only real size event, but it’s a cruel joke. The swell jumps to 7ft from the north with a short, weak period of 7 seconds, and the wind is a strong cross-onshore blowing at 18 to 25 mph. That’s a powerful, lumpy, messy closeout. Combined swell energy hits 483 for a time, so there’s plenty of water moving, but for a paddle surfer? It’s a washing machine. This setup looks much more interesting for kite surfing than paddle surfing. Definitely for experienced crew only, if anyone is game.
After that, it settles back down. From Saturday the 29th of August through to the end of the window on Friday the 4th of September, we’re back to tiny waves and light to moderate winds. There’s a tiny glimmer on Wednesday the 2nd of September afternoon – a 6ft north swell rolls in with a clean offshore wind (SW at 22 mph), but the period is only 6 seconds and the score is marginal. It’s a short, choppy, on-the-bump session for the desperate. Thursday the 3rd of September offers a 4ft north swell (period 8 seconds) with light winds, making for surfable waves but very ordinary conditions. It’s not a standout by any stretch.
The best on offer in this whole period – and I’m using the term loosely – is that Thursday the 3rd of September morning. A 4ft north swell with clean conditions and light winds. It’s small, but at least you won’t be getting thrashed. For the rest, it’s a long wait and a whole lot of nothing.
Rusty.

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.
