The Lowdown

Right, mate, grab a seat. Rusty here, and I’ve got the lowdown on what’s happening at Kahutara. It’s a reef and point setup, wicked for beginners when it’s clean, and it’s pretty exposed to the south swell window, though it loves a good SSE swell direction. The water temp is sitting at 52°, which is about average for this time of year, so you won't need a steamer over a spring suit just yet.

First off, don’t even bother looking at the next few days unless you’re desperate for a paddle. Tuesday morning to Thursday afternoon is all tiny, weak dribble – we’re talking 1 ft to 1 ft swell with combined energy barely tickling 30 to 112 (weak). The winds are clean enough, offshore and light, but the swell is just not there. It’s poor surf conditions, and you’d be fighting for scraps.

The real story starts to build on Friday the 17th. Friday morning we see a jump to a solid 7 ft swell from the south with a long period of 15 seconds – that’s proper groundswell, and the combined energy is a hefty 2530 (strong). But there’s a catch: the wind is a light cross-shore (NNE), and the report flags it as marginal because of questionable tide. That 7 ft at Kahutara’s point could be pushing into expert territory and getting a bit unruly with the long period. Friday afternoon drops to 5 ft and gets a cross-onshore, making it choppy.

Now, mark your calendar for Saturday the 18th. That’s the standout of the week. Saturday morning you’ve got a smooth 5 ft swell from the ESE (15 seconds), but the real magic is 3 mph offshore wind from the west. It’s clean, and the combined energy is 1149 (moderate to strong). The report says “excellent surf conditions for experienced surfers,” and I back that. That point is going to hold some nice lines. The swell direction isn’t quite the optimum SSE, but with that glassy offshore, it’ll be a top session.

Sunday the 19th is also a gem. Morning delivers 4 ft from the south (16 seconds) with glassy conditions – the wind is dead calm, literally “glass.” Energy is 1164 (moderate to strong). That’s another one for the experienced crew, but it’ll be super clean. The afternoon stays glassy with 3 ft, so you could get two sessions in.

Looking further out, from Monday the 20th through Thursday the 23rd, it drops back down to smaller, weaker stuff (2 ft to 3 ft), though winds stay light and mostly glassy. The week from the 24th to the 29th gets more interesting again. Saturday the 25th morning has a 5 ft ENE swell with a clean, light offshore – good fun for intermediate and up. Then Sunday the 26th morning is a beauty: 6 ft swell from the ENE (12 seconds) with glassy conditions and combined energy of 992 (moderate). That’s a solid, clean wave.

Hold up for the 29th, Wednesday morning. We get a 6 ft SSW swell with an 8-second period (short period wind swell) and glassy winds. Energy is 666 (moderate). That’s another “expect very good surf conditions” call, and with the optimum swell direction being close to this, it could be punchy and fun. Just remember that 6 ft is pushing into expert territory for this spot.

If you’re after the absolute best, Saturday the 18th morning and Sunday the 19th morning are your days. Get there early for the offshore/glassy windows. The swell is big enough for a proper ride, but the winds are just right for Kahutara’s point to shine.

Rusty, signing out.

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.
