The Lowdown
Hey, Rusty here. Let’s talk about what’s coming.
Truth is, this 16-day outlook is pretty grim. There’s a whole lot of nothing on offer, with a huge gap of tiny, poor surf across most of the first week and beyond. You’re basically waiting for a couple of marginal windows.
The only time you might want to be in the water is around Monday the 7th of September. On Monday morning, Tawharanui gets a pulse to 4ft from the NNW, with a period of 8 seconds. The combined swell energy reads 231 – moderate push – and with a cross-offshore wind from the W at 12 mph, it’ll be clean, but it’s still just marginal. By Monday afternoon, the wind goes offshore from the WSW at 12 mph, the swell drops to 4ft, and the energy is 144. It’s surfable, but very ordinary. After that, it fades out.
Then it’s dry for days. On the 15th of September, another Monday, the early morning shows a bump to 5ft from the NNW, but the period is only 5 seconds and the energy is 141. That’s weak, short-period junk. The cross-offshore wind from the W at 12 mph will keep it clean, but it’ll be fat and messy. After that, it’s back to knee-high or smaller, clean but gutless, for the rest of the 16 days.
Water temp at Tawharanui is 57°, which is about average for this time of year – nothing special.
The best call is Monday morning the 7th. That’s the only real pulse of the whole forecast. Tawharanui is a beginner-friendly beach and reef that’s fairly consistent when there’s swell, but crowds are often, so you’ll have company. The swell direction (NNW) isn’t matching the optimum NE line for the break, so it’ll be a bit off.
The rest is a long flat spell. It’s a tough run, but these quiet periods don’t usually last forever. Keep checking back.
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.
