Alright folks, Rusty here. Let’s break down the next couple of weeks at Kahutara. It starts off real mellow, but there’s some fire waiting for those who can hold out.
The first few days are a slow burn. Monday the 13th to Wednesday the 15th is all small and weak. We’re talking 1 to 2 ft waves with hardly any energy (66 to 92). Not worth suiting up for anything special. Wednesday afternoon does go glassy, but with a wave under 1 ft, it’s barely a wrinkle.
Thursday the 16th afternoon shows a pulse of life: glassy clean 2 ft swell from the ESE with a 16-second period. That’s long-period groundswell and the energy jumps to 230 – moderate now. Still small, but you’ll feel some push.
Friday the 17th into the weekend is the real deal. Friday morning glassy, offshore, clean 4 ft swell from the ESE with a 16-second period. Energy hits 1308 – strong. The wave comment says excellent for experienced surfers. At 4 ft, it’s a solid intermediate to advanced wave, especially with that long period. Kahutara’s reef and point will love it. Water temp is 52°, right about average for the time of year.
Saturday the 18th keeps the stoke: morning glassy with 5 ft from the ESE at 15 seconds, energy 1050. Still strong, still clean. The afternoon switches to a 3 ft swell from the S with a very long 23-second period – energy jumps to 1627. That’s a ton of power for the size. That long-period S swell will wrap nicely around the point but might be a bit straight on the beach. On the reef, it’s a dream.
Sunday the 19th morning continues the run: offshore, clean, 4 ft from the S with a 16-second period, energy 1254. Excellent. The afternoon gets a cross-onshore breeze and turns marginal, so get it in the morning.
The second week gets rougher. Monday the 20th through Tuesday the 21st has decent swell – 3 ft to 5 ft – but onshore winds and light rain ruin the quality. Energy is moderate to strong (511 to 1468), but the session won’t be pretty.
Wednesday the 22nd morning goes glassy again with 4 ft from the SSE at 10 seconds, energy 440. Good, but not the epic stuff from the prior weekend.
Thursday the 23rd morning is cross-off and clean with 4 ft from the SSE, energy 398 – a solid midweek option. The afternoon turns cross-onshore and messy.
Friday the 24th and Saturday the 25th fade back to tiny waves – 1 ft to 3 ft – with decent wind at times, but the energy is low (136 to 197). Glassy, but flat.
Then Tuesday the 28th afternoon throws a curveball: a glassy 7 ft swell from the ENE with a short 7-second period. Energy is 518. Over 7 ft is expert-only territory, and with that short period it’ll be a powerful, bumpy close-out on the beach. For the experienced crew at the point, it could be a punchy novelty session. Not the same quality as the first weekend, though.
The clear winner is Friday the 17th through Sunday the 19th. Friday morning and Saturday morning are the absolute peak – clean, strong, long-period swell with perfect wind. That’s your window.

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.
