The Lowdown
Alright mate, Rusty here, with a look at what's on the cards for the next couple of weeks.
To be straight with you, this is a tough run. We’re looking at a long, quiet spell, so don’t get your hopes up too early. The only real spot in the mix is Inner Cut (The-Cut-Nelson-Harbour), a point break that can be a bit inconsistent. The water is sitting at 53°F, which is a touch cooler than usual for this time of year, so you'll want a decent wetsuit.
The only real pulse of energy we see is a small window on Thursday the 13th of August. Thursday afternoon sees a tiny bit of life, with a 3 ft swell from the north, but it's a weak, short-period wind swell with a combined energy of only 105. The wind is glassy though, coming from the NE at 3 mph, which is a massive positive for the conditions. It’s surfable, but very ordinary. Don't expect much.
Then it goes dead. From Friday the 14th of August right through to Monday the 24th, it’s almost a total blank. There are a few days with tiny, near-flat bits of energy, but nothing worthwhile. That’s a solid ten days of flatness or near-flatness, which is a tough stretch.
Things start to stir again on Tuesday the 25th of August. Tuesday afternoon sees a jump in size with a 4 ft swell from the north, and the combined energy climbs to 192 (moderate). The period is short at 9 seconds, and the wind is a cross-onshore from the west at 12 mph, making it choppy. It’s still considered poor surf conditions, but it’s the most energy we’ve seen in a while. The next morning, Wednesday the 26th of August, is glassy with an ESE wind at 3 mph, and a 3 ft north-northeast swell. It’s surfable, but again, very ordinary.
Further out, Friday the 28th of August has a morning with a 3 ft north swell, glassy conditions, and a combined energy of 83. The afternoon pushes up to 4 ft from the north with a combined energy of 150, but a light cross-onshore wind messes with the quality.
So, for the standout, you’re looking at Thursday the 13th of August afternoon. It’s the only session with a pulse and glassy conditions. It’s not great, but it’s the best of a very quiet bunch. The rest of the forecast is a write-off until the final week, where we see some signs of life but nothing that’s going to set the world on fire.
Rusty.

Information about the Inner Cut Surf forecast
The above surf forecast table for Inner Cut provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Inner Cut can be found by selecting the local surf guide option on the grey menu. Our Inner Cut 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 (Inner Cut) 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 Inner Cut 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.
