The Lowdown
Alright, this is Rusty. Let's talk about what's on the menu for Kahutara.
First up, we've got a bit of a slow start. The early part of the week is pretty flat and messy, nothing to get excited about. You'll be waiting until the weekend of the 26th for the first real signs of life, and even then it's building.
The standout window is shaping up to be from Monday the 27th through to the end of the month. We've got a solid pulse of long-period groundswell filtering in from the east and southeast. The water temp is sitting around 51.4°, which is pretty average for this time of year, nothing unusual there.
For the best bet, I'm looking at Kahutara itself. This reef and point setup is a classic for a reason. The real magic happens on the morning of Monday the 27th, with a clean 3.6 ft swell from the east, a period of 14 seconds, and a gentle offshore breeze from the west. The combined energy is moderate (955), and the wave shape is going to be proper. The wind stays light and offshore, so you're looking at clean, lined-up waves. This is a great one for the intermediate crew, not too big, not too small.
Then we get a bit of a spike. The 28th brings a bigger 8.2 ft swell from the ESE, again with a 14-second period, but the wind turns cross-offshore in the morning. The energy is strong (2401), and this is the spot for experienced surfers only. The 29th is even cleaner, with a 7.5 ft ESE swell and glassy offshore winds in the afternoon. That's a serious session for the lads who know what they're doing. Crowds are "sometimes" a factor here, so keep an eye out.
There's a big gap starting Thursday afternoon the 30th as the wind nukes, and then it gets messy again with onshore winds and rain. That run lasts through the first weekend of August, with some lumpy, cross-off conditions. The swell sticks around, but the quality drops.
Now, for the long-range gold. Look at Monday the 3rd of August. That morning, we have an exceptional 13.1 ft southeast swell with a 12-second period, and the wind is a clean offshore from the WNW. The combined energy is a massive 5174. This is a serious, serious groundswell for experts only. It's a week and a half out, so it's a promise, not a guarantee, but if it holds, that's a day for the memory bank. The following morning, the 4th, still has a solid 7.9 ft swell, but the direction swings more southerly, making it better for the more experienced crew.
Overall, the first week is a slow burn, but the second week has a proper pulse. Don't sleep on the 27th for a fun, clean surf, and mark your calendar for the 3rd of August if you've got the bottle.

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.
