The Lowdown
Alright, this is Rusty. Let's have a look at what's shaping up for Kahutara over the next couple of weeks.
Alright, Kahutara, a reef and point set-up that’s fairly consistent and exposed to the south swell. Right now, the water temp is sitting at 50°, which is pretty much what you’d expect for this time of year, nothing weird there.
We’ve got a bit of a slow start, but things kick off this Monday morning with a solid 6ft S swell pushing in with a long 14-second period. The energy is strong, measuring 1278, and we’ve got a clean, light offshore wind from the NW. This is solid, clean surf, but that 6ft is getting up there, so it's more for the experienced crew.
By Tuesday the swell drops back, but the wind stays favourable. On the 25th, both morning and afternoon see offshore winds with 2ft to 2ft of S swell, but the energy is way down. It’s clean, but small.
Wednesday the 26th is similar, small and clean in the morning with a cross-off breeze, but it’s not exactly going to get the heart racing.
Then Thursday the 27th looks a bit of a mess with a bigger 6ft S swell, but the wind is cross-onshore and it’s going to be choppy. Not the one.
Friday the 28th and Saturday the 29th are small and clean, but nothing special. The energy is low.
Now, Sunday the 30th is a write-off. Strong winds and tiny, weak surf. The energy drops right off to 133. Not worth getting wet.
Monday the 31st is small but clean again, with a bit of a longer period SSW swell.
The real standout comes on Tuesday, the 1st of September. This is the one to circle. We’re looking at an 8ft S swell early, easing to 7ft in the afternoon, and it’s glassy. Completely flat, no wind. The wave energy is pumping at 2011 in the morning. This is excellent, powerful surf, but at that size, it’s strictly for experts. Kahutara’s reef and point set-up will handle that long-period S swell beautifully. Crowds are sometimes an issue here, so you might have some company.
The rest of the first week of September sees smaller, cleaner conditions, but nothing that compares to that Tuesday. The 2nd gets a bit windy, and the 3rd is clean but small.
Then we’ve got another promising window on Sunday the 6th of September. Another glassy morning with a 4ft S swell, but the period is a massive 17 seconds. The energy is strong at 1058. That’s going to be clean, powerful, and well-shaped on the point. Again, more for the experienced surfer.
The following week has some clean, smaller days, but nothing to get too excited about. The 8th of September looks okay with a long-period swell and clean conditions, but it’s still over a week away, so keep an eye on it.
Overall, the first week is a bit patchy, but that Tuesday the 1st is the clear winner. Sunday the 6th is a solid backup. Get on it if you can handle the size.
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.
