The Lowdown

Alright, let’s talk Kahutara (reef and point). Water temp is about 51°F, which is pretty normal for the season.

The first few days are a slow start. Wednesday the 15th has 1ft of swell with a long 16-second period, but it’s dead glassy – clean, but tiny. The combined energy is weak (96). Thursday the 16th morning bumps up to 2ft with a 13-second period and a light offshore wind from the west, making for clean little waves. Still small.

Friday the 17th morning is the first real highlight. We’ve got 4ft of swell from the ESE with a 16-second period, and the wind is a light cross-offshore from the WSW. The combined energy jumps to a strong 1470, and it’s clean. This is proper surf for experienced surfers. The reef-and-point brake will love that long-period groundswell.

Saturday the 18th is another cracker. Morning brings 4ft from the south with a very long 23-second period – that’s serious groundswell, and with a light offshore wind from the west, it’ll be glassy. The energy is pumping at 2219. By the afternoon, it’s still 5ft from the south, 19-second period, and glassy with a light SSE breeze. That afternoon session is the best of the whole run – clean, solid, and powerful. Sunday the 19th morning keeps the goods coming with 5ft south swell, 16-second period, and glassy conditions. The energy is strong at 1597. This is top-tier stuff.

The swell stays solid but winds get a bit tricky from Sunday afternoon through Monday. Monday the 20th morning has 6ft from the south, 15-second period, but with a cross-shore wind, so it’s a bit lumpy. The energy is still very strong (1620), but the cross-shore dulls it. Monday afternoon sees 6ft with a cross-onshore wind, making it choppy. For the kooks, this is more for the hardcore.

Tuesday the 21st morning is a hidden gem – 5ft south swell, 13-second period, and glassy as anything. The energy is moderate (766), but the clean conditions make it a solid session. After that, the swell starts to fade from Wednesday the 22nd onwards, with heights dropping under 3ft and energy falling off. There’s a little spike on Sunday the 26th with 4ft from the south and a 10-second period, but it’s light rain and cross-onshore, so it’s messy.

The real standout is Saturday the 18th afternoon and Sunday the 19th morning – that’s the pick of the whole forecast. Big, clean, glassy swell with serious energy. Crowds are “sometimes” at Kahutara, so you might have a few buddies out, but it’s not a madhouse.

The end of the run, around the 29th and 30th, has a rogue 7ft close-period (7-second) swell on the 29th afternoon, but it’s short-period junk and cross-shore wind – not worth paddling for. The 30th morning has 5ft with a cross-offshore wind and a 8-second period, which is okay but nothing special.

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.
