Table - best surf conditions forecast for Tawharanui over the next 16 days.
The Lowdown
Alright, Rusty here. Let’s break down what’s coming for Tawharanui.
The next few days are a total dead zone. From Monday the 24th of August right through Friday the 28th, it’s flat, tiny, and not worth a second look. You’ll be waiting.
Saturday the 29th of August is the only real chance. Saturday morning brings a 4ft swell from the north, with a short 6-second period. The wind is light offshore from the southwest, so the surface is clean. The combined wave energy is moderate (144). It’s surfable, but nothing special. Then Saturday afternoon, the swell holds at 4ft from the north-northeast, with a 7-second period, and the wind stays light offshore. The combined energy jumps to a solid moderate (254). That’s your best window. Clean, fun, but not a classic.
The rest of the forecast is a mix of small swell and strong winds. Sunday the 30th has a weak 2ft to 2ft northeast swell, but the wind is a fresh 22 mph from the west-southwest. Clean, but way too small. Monday the 31st is the same story. The first few days of September bring some weak, short-period north and northeast swell, but nothing worth chasing.
There’s a pulse on Friday the 4th of September, with a 6ft north swell. The period is only 6 seconds, and the wind is light cross-onshore. The combined energy is strong (266), but the conditions are only marginal. The swell is big enough to be a handful for beginners, and the wind will put some texture on it.
Water temp is 57°F, which is about 0.9°F cooler than normal. Nothing wild.
So, the only real call is Saturday afternoon, the 29th of August. It’s the cleanest, most fun option in the whole stretch. After that, it’s a long, quiet wait. Don’t hold your breath.
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.
