The Lowdown
Alright, Rusty here, taking a look at what's on the menu for the Tawharanui region over the next couple of weeks.
Straight up, this is a slow start. We're looking at a pretty big gap with nothing worth paddling out for. From now through to the 23rd of August, it's a write-off. Tiny, weak, and messy. The water temp is sitting at 58°, which is right on the money for this time of year, so nothing weird going on there.
The first real sign of life hits on Monday the 24th. The morning shows a pulse of 6ft swell from the north, but it's a short-period 6-second wind swell. The combined energy is moderate (229), but it's clean with a light breeze. It's a bit of a messy, lumpy wave for a beach and reef setup, and honestly, it might be more interesting for the kite surfers than us paddle guys. The afternoon gets messy with a fresh 19 mph cross-offshore wind, so that window is tight.
Tuesday the 25th is surfable but ordinary. The swell drops a bit, but still clean with a moderate offshore wind. Wednesday the 26th is similar, with moderate offshore winds, 4ft to 5ft from the north, but the period is still short. Nothing to get excited about.
Now, the standout. Thursday the 27th of August. This is the one. We've got a solid 10ft swell from the north-northeast. The combined energy is massive (1197), so there's plenty of grunt. The wind is light from the west, making it clean. The period is 8 seconds, which is short, so it'll be a bit dumpy and powerful, definitely for experienced surfers only. The afternoon drops to 6ft and cleans up nicely, still a great option. Friday the 28th holds on with 6ft to 7ft, clean and light winds. That Thursday morning window is the best on offer.
The very end of the run, Saturday the 29th, gets choppy again with a cross-shore wind, so that's a no-go.
So, the call: it's a long wait, but Thursday the 27th morning is the one to circle. Big, powerful, clean swell. Don't bother before the 24th.
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.
