The Lowdown

Right, let's have a look at what’s on offer for Kahutara over the next couple of weeks. It’s going to be a mixed bag, but there are a few sessions that have me proper excited.

The water temperature is sitting at 51°, which is about 0.5° colder than usual for this time of year, so pretty much what you’d expect.

We’re starting off a bit slow, but things really kick off. Saturday has a tiny 1ft swell from the south with a very long 17-second period, but it’s pretty weak with a combined energy of only 117 and it's raining. Not one to get wet for. The standout of the whole period is hands down Tuesday the 28th of July. The morning session is looking bloody brilliant. You’ve got a clean 6ft swell from the ESE, a period of 12 seconds, and a massive combined energy of 1126. To top it off, the wind is glassy from the NNW. That’s prime surf. It’s a bit sizey for beginners, but for experienced surfers, this is the call. The afternoon gets a bit messy with a cross-on wind, so get in early.

Sunday the 26th morning is also a beauty. The swell is a smaller 3ft from the ESE, but with a very long 15-second period and a combined energy of 548. The wind is glassy from the WNW, so it’ll be clean as a whistle. Perfect for a longer board.

Monday the 27th morning is clean with a 4ft easterly swell, and the afternoon glassed off with 4ft waves. Good, fun waves. Wednesday the 29th and Thursday the 30th mornings both offer clean, offshore conditions, with the swell dropping from 5ft to 4ft. Solid, clean waves.

There’s a clear gap in quality from late Thursday the 30th through Saturday the 1st of August. The wind gets messy and the swell drops right off. Then Sunday the 2nd of August morning looks tidy again with glassy conditions and a 3ft south swell with a long 16-second period. It’s small but clean.

After that, the wind turns nasty. Monday the 3rd to Tuesday the 4th of August gets blown out with strong, cross-shore winds and lumpy, short-period chop. Not worth it.

Then we get another run. Wednesday the 5th of August through to Friday the 7th of August sees a healthy run of south swells, between 5ft and 6ft, with long periods of 14-16 seconds. The wind is mainly cross-offshore, so it’ll be clean. Friday morning the 7th has a 6ft swell from the south with a combined energy of 1445 and a light cross-offshore breeze. That’s excellent. Friday afternoon then goes glassy with a 6ft south swell. That’s a great end to the run.

The last few days, the 8th and 9th of August, drop back down to 3ft to 4ft waves. Clean enough, but nothing special.

So, for the best wave, get on Tuesday the 28th of July morning. For the best run of quality, the window from Wednesday the 5th to Friday the 7th of August is your target.

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.
