Alright, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We're starting off a bit slow, but there's a real humdinger of a swell lining up in the second week if you've got the patience. The first real action doesn't kick in until Friday the 10th. Before that, Thursday the 9th shows a solid 8ft swell from the east, but the wind is a messy cross-shore, coming in at 16 mph, and the water is just average for this time of year at 52°F. It's a write-off for a paddle.
Friday the 10th is where we start to see some life. Kahutara will have a clean 7ft easterly swell in the morning with a 9 mph cross-offshore breeze from the WSW, and the period is a solid 11 seconds. The combined energy is strong (1170). This is proper groundswell, and it's going to be a bit much for the beginners, but for the experienced crew, this is a great session. The afternoon drops a touch to 6ft but stays clean.
Saturday the 11th is a real treat. The morning brings a clean 4ft easterly swell with a 6 mph offshore wind directly from the WNW. The period is 10 seconds, and the energy is moderate (586). Then, Saturday afternoon gets glassy. A 4ft easterly swell with a 3 mph glass-off from the SE. That's as good as it gets for clean conditions. It's a small window but a mighty fine one.
Sunday the 12th sees a shift. The morning has a tiny 2ft southerly swell with a very long 16-second period. The energy is weak (465), and while it's clean, it's not going to give you much to work with. The afternoon is a write-off with a cross-on breeze.
Things then go very quiet. From Monday the 13th through to Wednesday the 15th, the swell drops right out. It's tiny, with energy values dropping to as low as 49. You're looking at a gap of a few days with pretty much nothing worth paddling out for.
Thursday the 16th shows a pulse of long-period energy coming through, with a 3ft easterly swell at 15 seconds, but the energy is still low (397) and conditions are only marginal.
Now, here's the standout. Friday the 17th morning is a gem. A 3ft swell from the ESE with a 13-second period and glassy conditions from a light NW breeze. The energy is building (684), and it's going to be clean as a whistle. This is the one to circle.
But the real monster is brewing for the second week. Saturday the 18th morning is for the experts only. A solid 7ft ESE swell, with a 14-second period, and a clean 6 mph cross-offshore breeze from the SW. The energy is strong (1606). This is a powerful, long-period groundswell that will be breaking with authority. Kahutara is a reef and point, so it should handle that long period well, but it’s a serious session.
And then, hold onto your board. Friday the 24th. We're looking at a massive 13ft easterly swell. The energy is just insane (8792). The wind is only a light cross-on, so it won't be completely clean, but for a true big-wave charlie, that's the call of the trip. It's a long way out, so don't bet the house on it, but it's a real promising sign to finish the forecast.
So, the pick of the week is Saturday morning the 11th for the glassy fun, and the big one to watch is Saturday the 18th morning for the experienced crew. The 24th is a wildcard for the brave.
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.
