The Lowdown
Alright, grab your wettie, let’s check out what’s on the menu at Tawharanui. It’s a beach and reef setup up here, and for the next few days it’s looking pretty darn quiet. The water temp is hanging about where you’d expect for this time of year, nothing weird going on there. We’ve got a bit of a wait ahead, though – from now until the afternoon of Saturday the 8th, it’s mostly tiny, weak, and not worth paddling out for. The combined swell energy is barely ticking over, mostly in the single or low double digits, so you’re looking at a real flat spell. Kite surfers might find something to do, but for a surfboard, it’s a snooze. Then, on the morning of Sunday the 9th, we get a solid pulse: a 8ft groundswell from the NNW with a period of 7 seconds, but the real kicker is the energy jumping up to 652 – that’s a solid wall of water. The wind is offshore and light in the morning, going dead glassy by the afternoon. This is the real standout of the whole 16-day window – clean, punchy, and good for experienced surfers. Just know that at that size, it’s too much for beginners. It cleans up nicely, but the wind shifts on the Monday the 10th and turns it into a lumpy mess, so don’t sleep on that Sunday. After that, the back half of the forecast gets patchy again, with a few small, clean windows around the 13th and 14th, but nothing with the power of that Sunday swell. The 16th has a little bump with clean offshore wind, but it’s small.

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.
