The Lowdown
Right, mate, Rusty here. Let’s have a look at what’s cookin’ for Tawharanui.
Honestly, I’m struggling to find a reason to get wet. The next sixteen days are a real quiet stretch. We’re looking at a long, long gap with no real surf to speak of. The first spot of hope doesn’t even show up until Tuesday the 8th, and even then it’s a real small affair.
The water temp is sitting at 58°, which is pretty much bang on average for this time of year.
Tuesday morning, the 8th, is the only thing that even gets a nod. It’s a tiny 2ft of swell from the N, with a period of 8 seconds. The wind will be offshore from the SW at 16 mph, which will keep it clean for the beginners out there. The combined energy is a weak 70. It’s surfable, but it’s flat out ordinary. Not a standout, just the only option.
After that, it’s a long, flat run. The rest of the 16-day window is filled with tiny, energy-less waves, mostly under 1ft. The wind is often offshore, but it’s either too strong, making it a battle to paddle into, or the swell just isn’t there. A few times the wind hits 25-28 mph, which is proper strong and makes it tough going. We see a few pulses of very long period swell (14-15 seconds) on the 9th, 10th, and 11th, but the swell height is a pathetic 0.3ft to 1ft, so it’s not doing anything.
This is a classic case of no good surf options in the window. For a spot like Tawharanui, these blank runs aren’t unusual. It tends not to stay this poor for long, but for now, leave the boards in the shed. The setup with the strong winds and flat water looks more interesting for kite surfing than a paddle session.
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.
