The Lowdown
Alright, folks, Rusty here. Let’s break down what’s cookin’ for the Tawharanui area over the next two weeks.
Honestly, it’s a rough patch. We’re looking at a long, dry spell with no real surf to speak of. From the start of the period all the way through the end of August, the swell is tiny and weak – nothing that’s gonna get you out of bed. The wind is mostly cross or cross-off, but the waves just aren’t there. The combined energy is stuck in the low double digits – 10 to 55 – which is basically flat. There’s a little spike on the 28th of August with a combined swell energy of 152, but it’s a messy, short-period 5ft swell from the north with a fresh cross-shore wind and a lumpy cross-chop. That’s not surfable; it’s just a washing machine.
The only faint glimmer comes in the second week. On Thursday, the 3rd of September, the morning shows a 4ft swell from the NNW with a short period of 6 seconds, and the combined energy is 115. The wind is light offshore from the WSW, so it’s clean. The wave comment says "surfable waves but very ordinary conditions," so it’s a far cry from a standout, but it’s the only time in the whole 16 days the score even nudges above zero. If you’re desperate, that’s your window. The water temperature is around 57°F, which is pretty average for the time of year, so no surprises there.
Don’t expect much else. The rest of the first week of September runs flat again, with tiny swell and light winds. The crowd factor at Tawharanui is listed as "often," but honestly, you won’t have to worry about that because nobody will be paddling out.
This is a tough run for the area. We’ve got a solid 15 days of nothing worthwhile before that one ordinary morning on the 3rd of September. If you’re a kite surfer, that blustery 28th of August might be more your style, but for paddle surfing, it’s a big old blank.
Stay salty, everyone.
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.
