Table - best surf conditions forecast for Tawharanui over the next 16 days.
The Lowdown
Alright, Rusty here. Let’s size up what’s coming for Tawharanui.
It’s gonna be a tough run over the next couple weeks. Lots of poor to average days, with just a few moments where it’s worth paddling out. Water temp is 58°, right around normal for this time of year.
Your best chance is Monday morning, August 10th. Clean conditions with a light offshore breeze out of the SW and a north swell running 4ft, period about 8 seconds. Moderate energy at 226, and that glassy wind will have it looking nice. It’s a beach and reef setup that breaks fairly consistently, good for a beginner-friendly session.
Tuesday morning, August 11th, is another look. Smaller at 3ft from the north, but with a cross-off breeze keeping things clean. Energy drops to 127, so it’s not powerful, but it’s surfable.
Friday morning, August 14th, gives you a glassy start with 4ft from the north-northeast, but the period is short at 6 seconds, so it’ll be soft and a bit weak. Energy is 147.
From Saturday, August 15th onward, it’s mostly tiny, choppy, or blown out. There’s a long stretch of poor conditions all the way into the third week. Even the late swell around August 24th shows some size at 4ft, but it’s under a cross-onshore wind, so it’ll be messy.
The pick of the bunch is Monday the 10th and Tuesday the 11th. After that, you’re better off waiting.
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.
