The Lowdown
Alright mates, Rusty here, giving you the straight story for Tawharanui (Tawharanui). Gotta be honest, it's a bleak outlook for the next couple weeks. We're looking at a whole heap of flat days with barely a ripple to get excited about. Most of the month is a total loss.
Right now, it’s dead flat. The first time we see anything even close to surfable isn't until Monday, August 10th. And even then, it's only just barely. We get a 4ft north swell on Monday morning, but it's got a short, weak period of 8 seconds. The combined energy is only moderate (176). The wind is looking okay – a light offshore from the WSW – so the surface should be clean. That's the best we'll see for a while, and honestly, it’s pretty ordinary.
Tuesday, August 11th starts off interesting with a glassy morning on a tiny 3ft north swell, but it’s got no energy behind it (76). After that, it’s back to onshore winds and poor surf for the rest of the week.
We see a bump in size around Friday, August 14th, with a 5ft north-northeast swell... but it’s coming with a strong north cross-onshore wind that'll just tear it apart. It's got moderate energy (315) but it's a total washout for a paddle board. Might get some kite surfers out, but for the rest of us, it's a choppy mess.
The only other thing worth a mention is Saturday, August 15th. A clean 4ft northeast swell with a gentle offshore breeze from the WSW. The period is a slightly better 9 seconds, and the energy is moderate (189). It’ll be surfable and clean, but again, nothing to get too excited about.
After that, it’s a long slide back to nothing. The final two weeks just fade into tiny, weak waves and clean but empty water. It’s just one of those stretches where the ocean takes a long nap.
Stay patient, keep the board waxed, and check back. Forecasts can always change.
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.
