Table - best surf conditions forecast for Kahutara over the next 16 days.
Alright, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We’ve got a bit of a slow start, but it builds into a cracking run of surf. The first few days are pretty average, but the energy really starts to kick in around the middle of the second week and pushes through to some solid options. The standout window looks to be around Friday, July 17th and Saturday, July 18th, offering the best mix of size and conditions.
The first solid action is Friday morning, July 10th. Kahutara (reef and point) is seeing a 7ft swell from the ESE with a period of 11 seconds. The wind is a cross-off from the W at 9 mph, keeping things clean. This is one for the experienced crew, as the size is solid and the combined swell energy is strong at 1305. The water temp is 52°, pretty normal for this time of year.
Saturday, July 11th, the swell drops a touch to 5ft from the E, but the wind goes glassy in the afternoon from the SE. This is a beautiful call for a clean, smaller session with 607 wave energy. Sunday the 12th gets smaller again and the wind turns cross-on in the afternoon, so that morning window is your best bet.
There’s a quiet patch from Monday, July 13th through to Thursday, July 16th. Swell drops right off, with heights barely above 2ft and wave energy falling below 200 for a few days. The long period swell on Wednesday morning (19 seconds) is from the S, but it’s tiny at 0.7ft, so it’s not going to do much except maybe create some weird lines.
Now for the good stuff. Friday, July 17th, the swell jumps back up to 6ft in the morning from the ESE with a long 16-second period. Wind is a cross-off from the WSW at 16 mph, so it’s got some push but stays clean. Wave energy is pumping at 1392. This is a strong call for experienced surfers, as the size and power are there.
The absolute standout is Saturday, July 18th. Morning sees 6ft of ESE swell with that sweet 14-second period, and the wind is glassy from the NNW. Wave energy is 1328, and conditions are described as excellent for experienced surfers. This is the pick of the run – clean, powerful, and with real groundswell lines. By the afternoon the wind gets a bit cross-on, so get in early.
Sunday the 19th stays clean with glassy winds from the W and a dropping 4ft ESE swell. Monday the 20th is similar, with waist-high clean waves.
After that, there’s another pulse around Wednesday, July 22nd, with a 4ft swell from the S. The wind is a clean cross-off from the NNW, making for a tidy morning session. This is a solid backup option, but won’t match the July 17th-18th window.
So, to sum it up: the first week is quiet, but the second week delivers. The hands-down best sessions are Friday, July 17th morning and especially Saturday, July 18th morning. Get on it.
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.
