The Lowdown
Alright, Rusty here. Let's have a look at what's comin' for the Kahutara stretch.
Right off the bat, we’ve got some solid surf on the menu. Tuesday morning, July 28th, is lookin' real nice. The water's sittin' about average for this time of year, nothing out of the ordinary. That Southeast swell is pumpin' in at about 6 feet on a 13-second period, with a solid chunk of energy behind it. The kicker? Glassy conditions, a light WNW breeze. It’s gonna be clean, lined up, and all yours. This is a standout for the first week, no doubt. It’s a reef and point break, so that longer period will wrap in nicely. Keep in mind, 6 feet is gettin' a bit spicy for the groms, but for the experienced crew, it's perfection.
The glass holds through Tuesday afternoon, and Wednesday, July 29th, keeps the good times rollin'. A little smaller, around 5 feet, but still with that lovely ESE groundswell and clean, offshore or glassy conditions. Surfable, fun, and user-friendly.
Thursday, July 30th, the swell drops a notch to about 4 feet, and we get a cross-off shore breeze. Still clean, still fun, but the energy's down a bit. Friday, July 31st, is smaller again, around 3 feet. The wind stays offshore, but it's a weak, ordinary day.
Now, hold onto your board. Saturday, August 1st, we get a big spike. An 12-foot Southerly swell rolls in, with a massive jump in energy. But the wind is a strong, cross-off 30 km/h from the SW, and the forecast is calling it "marginal." That much swell at a reef and point with that much wind? It's gonna be a washing machine, not a wave. One for the jet-ski crew or the crazy brave, not for a pleasant paddle. Same goes for Sunday, August 2nd, with that 10-foot and 8-foot swell and strong cross-off winds.
We get a nice reset on Monday, August 3rd. The swell drops back to a clean 5 feet, the wind swings light offshore or goes calm, and the energy is back in the moderate range. It's a very good day.
Tuesday, August 4th, is our second big standout. A 6-foot Southerly swell, but with a period of 16 seconds. That’s proper long-period groundswell, and the energy is massive. The morning session has a light cross-off breeze, which should keep it clean. The caveat here is that long-period swell can be a bit straight at beach breaks, but at a reef and point like Kahutara, it's gonna unload beautifully. This one is for the experienced surfers who know their lineup.
The week after that is a bit of a mixed bag. Wednesday, August 5th, stays punchy with another 7-foot swell, but that 35 km/h wind is going to chop it up. Thursday, August 6th, is a story of its own: a massive 16-foot Southerly swell. The energy numbers are astronomical. The morning has a clean offshore wind, but the forecast is straight up sayin' it's too big for this break. That’s a hard pass for paddling, unless you’ve got a tow rope. Friday, August 7th, is more of the same with 16-foot and 10-foot swells and gale-force winds. Avoid.
The surf finally settles back down by the start of the second week. Monday, August 10th, brings a nice 6-foot SSE swell with moderate energy and a clean cross-off wind. A good, solid day. Tuesday, August 11th, is smaller at 3 feet, and things get a bit weak from there. The final days of the outlook, Wednesday, August 12th, are just small, weak, and with a cross-onshore wind. Not worth paddlin' out for.
So, to wrap it up: The standout is Tuesday morning, July 28th, and Tuesday morning, August 4th. The first is a glassy, consistent groundswell, the second is a powerful, long-period groundswell for the experts. If you're in the water on the 28th, you're gonna have a good time.
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.
