The Lowdown
Alright, Rusty here. Let's chew the fat on what Tawharanui's got in store. It's a slow start, but a big swell window is on the way for those who can wait.
Right now, Monday morning the 10th, there's a bit of fun to be had. Tawharanui is seeing a clean 5ft swell out of the north, with a light offshore breeze making things look real tidy. The water temp is sitting at 58°, which is pretty standard for this time of year. The combined energy is moderate at 269, so there's enough push for a beginner-friendly wave on this beach and reef setup.
That little window closes fast. From Tuesday the 11th through to Saturday the 15th, it's a grim stretch. The wind goes onshore or cross-shore, the swell drops, and the quality just isn't there. You're better off stayin' dry. There's a glimmer on Saturday morning the 15th when it goes glassy, but the swell is only 4ft and ordinary.
Then we hit a big gap. From Sunday the 16th all the way through to Friday the 21st, there's nothing worth paddling out for. The swell bottoms out, and even with some clean offshore wind, the waves are just too small to bother with.
Now, here's where it gets interesting. Saturday the 22nd of August starts to show some size, with a 7ft easterly swell rolling in, but the cross-onshore wind is gonna chop it up. Not the one.
The real standout is Sunday the 23rd of August. We've got a serious groundswell arriving from the northeast with a very long period of 12 seconds. The combined energy is a massive 2234 in the morning, jumping to 2858 by the afternoon. The swell hits 10ft by Sunday afternoon. This is expert territory, no question. The wind is light cross-onshore, so it won't be perfect, but the raw power is undeniable. This is the best on offer, but it's for experienced surfers only.
Following that, Monday the 24th of August is your pick for the best quality session. The swell drops to a still-chunky 7ft from the ENE, with that same 12-second period, but now we have clean offshore wind from the WSW. The combined energy is still strong at 1082. This is excellent surf, but again, only for experienced surfers given the size and power. The offshore breeze will groom it nicely at this beach and reef.
After that, the swell fades out again through Tuesday the 25th, and the run of good waves is over for the forecast period.
Signing off, 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.
