The Lowdown
Alright, let's talk Tawharanui in feet and miles. It's a pretty lean stretch, but there's a tiny window worth paddling for.
Your best chance is Tuesday morning, the 8th of September. We've got a little 2ft north swell rolling in with a short 8 second period. Water temp is 58°F, which is about what you'd expect. The wind is a clean offshore from the southwest at 12 mph, so the surface will be glassy. The combined swell energy is weak at 70, so it's not going to throw much power, but it's rideable. The afternoon drops to 2ft, so get on it early.
After that, the lights go out. From Tuesday afternoon right through to the 19th of September, it's a long stretch of tiny waves – mostly 0.3ft to 0.7ft. The wind is often clean, but there's just no ocean energy. The combined swell energy readings are mostly in the weak teens and twenties. It's a proper flat spell, and for this area, that happens.
Then, on Sunday the 20th and Monday the 21st of September, there's a slight bump to 3ft from the north-northwest. But the period is a shocking 5 seconds, so it's just messy windswell. The energy is still weak at 35-39. The wind is cross-offshore, so it'll be clean, but the wave quality is poor. It fades into the 22nd and 23rd with 1ft swell and near gale force offshore winds that'll make paddling a battle.
So, the only real nod goes to Tuesday morning the 8th. Grab your log, enjoy the 2ft north swell in the clean offshore breeze. After that, it's a waiting game.

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.
