The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for Kahutara. This is a reef and point setup, and it’s a beginner-friendly wave that’s fairly consistent. Right now, the water’s sitting at 50°F, which is just about normal for this time of year – nothing out of the ordinary there.
We’ve got a bit of a slow start, but once it kicks in, there’s some real quality on the cards. The first standout is Wednesday morning, August 5th. We’ll see a clean 10ft swell from the south with a solid 12-second period, pushing a strong wave energy of 2149. With a light offshore wind from the west, it’s going to be clean and powerful. This one’s for the experienced crew though – 10ft is expert territory.
Then, hold on to your board for Tuesday the 18th. The afternoon session brings a glassy 8ft swell from the SSW, 10-second period, and a massive energy reading of 2355. Conditions are perfect for experienced surfers with that glassy surface and a solid push from the south. That’s about as good as it gets here.
A few other mornings are worth a mention too. Thursday the 6th has a glassy 6ft from the SSE, and Friday the 7th offers a clean 3ft from the south with a very long 14-second period – that’s proper groundswell, and it’ll wrap nicely into the point.
Later in the second week, keep an eye on Monday the 17th morning. Glassy conditions with a 4ft swell from the SE, 12-second period, and 527 energy. It’s promising, but it’s further out so don’t lock it in just yet.
There’s a stretch from around the 11th to the 14th where it goes pretty flat or messy, with small windswell and cross-onshore winds – a few days of nothing to get excited about. But the run from the 5th through the 8th, and then again around the 17th and 18th, is where the magic is.
Crowds can show up here sometimes, so get in early on those standout days.
Stay stoked,
Rusty

Information about the Kahutara Surf forecast
The above surf forecast table for Kahutara provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Kahutara can be found by selecting the local surf guide option on the grey menu. Our Kahutara 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 (Kahutara) 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 Kahutara 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.
Kahutara is 106 km (66 miles) from the city of Blenheim. If you plan a holiday in Kaikoura and Marlborough, look for hotels and other accommodation in Blenheim. Blenheim has rooms for a wide range of budgets as well as car hire and transport links.
