The Lowdown
Alright, Rusty here. Let’s get real about what’s on the table.
Honestly, looking at the whole 16-day run, it’s a quiet spell for Tawharanui. There are no standouts, and a lot of days you’ll be staring at flat or near-flat water. For most of the first week and into the second, the swell heights are barely a ripple—0.3 feet to 1 feet—with weak energy readings, mostly in the teens or twenties. The wind is often offshore or clean, which would normally get a bloke excited, but without any push from the ocean, it doesn’t matter.
There’s a notable gap of nothing worth paddling for from September 11 right through to the 19th. That’s over a week of poor surf conditions, with scores at zero across the board.
Then, on Saturday the 20th of September, there’s a small pulse. The morning shows 4 feet swell from the NNW, with a combined energy of 196—moderate energy for once. But the period is only 8 seconds, so it’s a short-period windswell, not the kind that wraps in clean. Still, with WSW winds at 15 mph blowing offshore, it’ll be clean. That’s the best on offer, if you can call it that. For a beginner-friendly beach and reef setup like this, it’s at least rideable. But don’t expect pumping barrels.
After that, it fades back to tiny again. The last few days, like the 24th, show a small 3 feet ENE swell with a bit more energy (123 in the morning), but the wind is cross-shore, making for a chop. Nothing special.
So, the honest truth: there’s no real highlight here. The water temperature anomaly isn’t given for this break, so we’ll skip that. If you’re desperate, the morning of the 20th is the only flicker of life. Otherwise, maybe give the board a rest and check the forecasts again soon—they can change.
Stay tuned,
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.
