The Lowdown

Alright mate, Rusty here with the long-range look at what’s on the cards for the next couple of weeks.

First up, we’ve got a solid run of clean surf coming through on Monday morning, August 3rd. Kahutara is a reef and point set-up that’s fairly consistent, and it’s exposed to the swell. The water is sitting at 51°F, which is pretty bang on average for this time of year, so no surprises there. Monday morning kicks off with a clean 3ft swell from the south, 12-second period, and a light offshore breeze from the west-northwest. The energy is moderate at 568, but the conditions are looking very good for a session. By Monday afternoon, the wind picks up a bit but stays offshore, and the swell bumps to 4ft from the south, with moderate energy (623). A solid start.

Tuesday morning, August 4th, is a different story. The swell jumps to 13ft from the south, period drops to 11 seconds, and the wind swings cross-off from the southwest. That’s a lot of juice – the energy is massive at 4479 – but this is only for the experienced crew. The wind is fresh, so it’s going to be a handful. Conditions are still clean, but anything over 8ft is expert territory. Tuesday afternoon stays similar, energy slightly lower at 3549, but still a big, heavy swell.

Wednesday, August 5th, is the standout of the run. The morning brings a 10ft southerly swell, 12-second period, a light offshore from the west, and the energy is still strong at 2133. This is excellent for experienced surfers. Clean, powerful, and the wind is perfect. The water temp is still in that normal range, and the reef and point setup will handle the size well. One to circle on the calendar.

Thursday, August 6th, the swell drops to 5ft from the southeast, period 10 seconds, and the energy backs off to 689. Light offshore in the morning, clean conditions. Fun and manageable for a wider range of skills. Friday, August 7th, we get a long-period 4ft southerly swell at 14 seconds, and the energy is moderate at 768. The wind is light offshore, making for clean lines. The longer period means better shape but longer waits between sets – that’s fine for the point break.

The weekend, August 8th and 9th, is glassy. Saturday morning has a 4ft south-southeast swell, 11 seconds, and glassy conditions with the wind off the west. Energy is a bit lower at 360, but it’s clean. Sunday similar, with a light cross-off wind and a 4ft swell. The energy drops to 310. Good for a cruise.

From Monday, August 10th, the surf winds down. The swell drops to 3ft, then 1ft, with weak energy. There’s a gap of a few days where the recommendations are poor or marginal. The energy struggles to hit 200. Not much to write home about.

Midweek, August 13th, things pick up again. Thursday morning brings a 8ft swell from the east-southeast, 9-second period, and the energy jumps to 1015. That’s strong, and the wind is light cross-off, keeping it clean. This is excellent for the experienced crew again. Friday the 14th still has some clean 5ft surf, but energy drops.

The second week shows a bit more promise toward the end. Sunday, August 16th, has a 7ft east-northeast swell, 9 seconds, energy at 709, and light cross-off winds in the morning. The afternoon turns glassy with a 6ft swell. Good signs, but we’re a bit further out, so treat it as promising but not locked in.

Best bet? Wednesday, August 5th morning. Clean, powerful, offshore wind, and the reef will handle it. Keep an eye on Saturday, August 16th afternoon, too.

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.
