The Lowdown
Alright folks, Rusty here. Let’s be straight with you – we’ve got a long, quiet stretch ahead for Tawharanui.
The whole 16-day window is looking pretty flat and uninspiring. There's no real surf on offer. The first few days are a washout with tiny waves and poor conditions. From Tuesday the 4th of August right through to Monday the 17th, every single session is tagged as "poor surf conditions." The swell heights barely climb above 0.3 ft to 4 ft, and the energy just isn't there. The combined swell energy stays weak, climbing only to 16 (16) at its best early on, and even when it nudges up to 211 (211) or 275 (275) on the 10th, the wind is onshore and messy, making it unsurfable. The small window of cleaner conditions on the 9th, with a 4 ft swell from the north and light cross-offshore wind, still only gets a "surfable waves but very ordinary conditions" tag – not worth paddling out for.
The only break in the file is Tawharanui, a beach and reef setup that’s fairly consistent, but it’s just not working for us. The swell direction is mostly from the north or northeast, which is exposed, but the periods are short and the energy is too weak to create anything rideable. The water temperature is sitting at 58°F, which is about normal for this time of year, so no surprises there.
It’s a tough one to call – there’s just nothing to get excited about. If you’re desperate for a paddle, maybe the 14th and 15th of August have some clean, offshore winds, but the swell is only 1 ft to 2 ft. Not enough to push a board. For the entire 16 days, it’s a blank run. Sometimes that’s just how it goes around here.
Stay patient, mates. The swell will turn.
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.
