Table - best surf conditions forecast for Kahutara over the next 16 days.
Alright folks, Rusty here. Let’s take a look at what’s coming up for the next couple of weeks. We’ve got a bit of a slow start, so don’t get too excited right away.
No real surf to speak of through the first few days. Monday the 13th and Tuesday the 14th are flat and pretty forgettable, so don’t bother paddling out. The energy is weak and the waves are tiny. It’s not until the back half of the week that things start to wake up.
By Thursday the 16th, we start seeing a little more life, but it’s still small with a moderate combined swell energy of 112. Clean conditions though, with a light offshore breeze from the WNW.
Now, the real standout is unmissable. Friday the 17th at Kahutara (reef and point) is looking like a proper session. We’re looking at a solid 13 ft swell from the SSW, with a very strong energy reading of 7998. That’s a lot of water moving around. This is a big, powerful groundswell with a period of 12 seconds—not quite the longest, but plenty of punch. The wind is a light 6 mph from the W, keeping it clean and cross-off. This is a day for experienced surfers only; that size is too much for beginners. The water is a mild 52°, which is about average for this time of year.
Saturday the 18th stays good, with a drop in size to 5 ft from the ESE but still packing a punch (1111 combined energy). The wind goes glassy in the afternoon, which is a huge plus. The swell period stretches to 14 seconds, giving some nice long lines, but at a point break like this, that’s a good thing.
Sunday the 19th is still solid, with 4 ft to 5 ft waves from the south. The morning is clean, but the afternoon gets a bit crossed up. The energy is still high at 1948, so there’s grunt in the water.
As we head into the second week, the surf holds. Monday the 20th and Tuesday the 21st are in the 5 ft to 5 ft range with glassy mornings and clean conditions. The waves do start to get a bit more onshore in the afternoons, so aim for the early sessions. The best of the late week looks like Wednesday the 22nd afternoon and Thursday the 23rd, with glassy conditions and 4 ft waves from the SSE and SE. The energy is moderate at 534.
By Friday the 24th, the swell drops off quickly and the wind picks up. The surf gets small and choppy, and I wouldn’t bother until Sunday the 26th, where we get a return to clean, glassy conditions with 3 ft to 2 ft waves. The last few days of the month are small but clean, with a long-period S swell on the 28th offering a bit of a last hurrah.
So, the clear winner is Friday the 17th for the big, clean, and powerful swell. Get on it if you’re an expert. For the rest of us, the mornings from Saturday the 18th through Thursday the 23rd are the best bet for solid, clean waves.
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.
