The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming our way for Tawharanui.
Honestly, the next week and a half is a bit of a flat spell. From now through the 23rd of August, we’re looking at tiny, weak swell with heights struggling to hit 2ft and combined wave energy mostly below 100. Most of that time the wind is clean or offshore, but there’s just not enough push to get excited about. There’s a few glassy mornings (like Thursday the 20th and Friday the 21st) but the swell is barely a ripple at 0.7ft. It’s a quiet stretch.
Then, things flip hard. On Monday the 24th of August, a proper pulse of swell arrives. Tawharanui (beach and reef) should see sets around 8ft to 10ft from the north-northeast, with solid energy values climbing to 759 and then 1434. That’s a big jump. The wind is offshore from the southwest – clean, well-shaped conditions. However, this size is for experienced surfers only; it’s well over 8ft in the afternoon. The water temp is sitting at 58°, about average for this time of year.
Tuesday the 25th is the standout. Morning has 8ft north-northeast swell with a moderate offshore from the south-southwest, and combined energy is over 1000. By the afternoon, the swell holds at 8ft but swings more northeast with a period around 10 seconds and a gentle cross-offshore breeze. Combined energy jumps to 2273 – that’s serious power. This is the best on offer. The waves will be clean, powerful, and lined up for the more experienced crew. It’s not for beginners.
After that, Wednesday the 26th through the end of the period sees a drop in size and a shift to an onshore east wind, making conditions messy and choppy. There’s a brief window on Saturday the 29th afternoon with 7ft east swell and glassy conditions, but the period is short at 8 seconds and energy is only 491 – it’ll be a bit fat and lumpy.
So, bottom line: sit tight through the flat spell, then mark your calendar for Monday the 24th and especially Tuesday the 25th. That’s your window for the real deal.
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.
