The Lowdown
Alright folks, Rusty here. Let’s have a look at what Tawharanui has lined up for us over the next couple of weeks. Straight up, it’s a pretty barren run. We’ve got a whole lot of days where the surf just isn’t worth paddling out for. The first real sniff of anything comes on the 8th of September, but honestly, we’re looking at a long stretch of quiet conditions.
The pick of a very average bunch is going to be the Tuesday morning of the 16th of September. That’s the best wave energy we’ll see, with a combined energy reading of 173 (moderate). Even then, it’s not going to be pretty. We’ve got a clean-looking setup, but the swell is a short-period 6 seconds and coming from the northwest at 5ft. That’s a windswell, not a proper groundswell, and with those short, weak intervals it’s going to be lumpy and not much fun for paddle surfing. For a beach and reef setup like this, the better bet might be the kite gear.
For the bulk of the period, it’s tiny. From the 8th through the 15th, the swell is mostly under 2ft, with combined energy rarely breaking 100 (weak). There are a few moments with clean winds and even glassy conditions on the 9th of September, but the swell is basically non-existent at 0.3ft. You’d be floating, not surfing. There’s a period on the 10th of September with a long-period 14-second swell, which would normally be promising, but it’s only 1.0ft – a whisper, not a wave.
Later on, around the 20th to the 23rd of September, the swell starts to bump up again, but the quality is still poor. The 22nd of September brings a 6ft to 7ft swell with combined energy climbing to 367 and 527 (moderate), but the wind turns cross-onshore or onshore, making a messy chop. By the 23rd of September, the swell hits 8ft with a combined energy reading of 1349 (strong), but again, it’s a cross-onshore mess. The period is 10 seconds, so it has some energy, but the conditions will be tough.
In short, there’s no standout session here. The best bet, if you’re desperate, is the 16th of September morning for a bit of size, but don’t expect any quality. Otherwise, it’s a waiting game.
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.
