Alright folks, Rusty here. Let's take a look at what's comin' our way for the next couple of weeks. We've got a bit of a mixed bag on the cards, but there are some definite windows to get excited about.
The pattern starts off a little messy, but hang tight. Sunday morning is a decent little window to start the week. A clean 5 ft swell from the ENE, light offshore winds from the NW – that's a good look. The wave energy is moderate at 361, and the water temp is sitting at 52°F which is about average for the time of year. Not a standout, but a nice, honest Sunday morning surf.
That afternoon, the wind swings onshore and things go a bit lumpy. Monday is a write-off, with a brief window of tiny, clean surf in the morning from a long-period groundswell, but it's just too small to get excited about. The rest of the week looks big and blown out – we're talking 8 ft to 12 ft of messy, cross-shore chop with heavy rain. That's not paddle-friendly. A heads up for the kite crew though, that Tuesday morning through Thursday with 10 ft to 12 ft of lumpy ESE swell and cross winds could be your jam.
Now, here’s where we get the first real standout. Friday, 10th July – the clouds clear and we get an excellent session for experienced surfers. 10 ft of clean ESE swell hitting Kahutara (New Zealand) with a nice 11-second period and a cross-offshore breeze out of the WSW. The energy is strong at 2231. That's a big, powerful, clean day for the crew who know what they're doing.
The weekend of the 12th settles down nicely. Sunday morning is a really good, clean option with 5 ft from the ESE and light offshore winds. The energy is still solid at 585. It's clean, it's fun, it's a good one for everyone.
The following week has more promise. Tuesday morning, 14th July is another standout for experienced surfers – a clean 8 ft swell from the S, light cross-offshore breeze, and a powerful energy reading of 1017.
But the absolute pick of the bunch, the true gem, looks like Wednesday 15th July. We've got a clean 8 ft groundswell from the SE with a very long 12-second period. The morning has a light offshore WNW wind, and the afternoon goes glassy – dead flat calm from the NNE. The energy is pumping at 1560 and 1402. That is a day for the point and reef at Kahutara, where that long-period groundswell will really wrap in and line up. That's your session to circle on the calendar, though being two weeks out, keep an eye on the forecast.
The days after that ease back down with clean, smaller waves into the 3 ft to 6 ft range, perfect for a longboard or a fun fish. We do fade out by the 20th of July with a long gap of small, weak surf.
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.
