The Lowdown
Alright, grab a seat, let’s talk about the next couple of weeks around here. Lookin’ at the charts, it’s gonna be a tough stretch for us. Honestly, there’s nothing on the cards that I’d paddle out for right now. The whole 16-day window is pretty much a write-off for decent surf. There’s a long, disheartening gap of several days where we’ll be looking at flat, calm water, especially from around August 17th right through to the end of the forecast. Not a lot of energy out there to get excited about.
We’re talking about Inner Cut (The-Cut-Nelson-Harbour) here. This spot is a point break, inconsistent by nature, and over this period it’s living up to that reputation. The water temp is sittin’ around 53°F, which is about normal for this time of year, nothing unusual there. The first couple of days, August 11th and 12th, offer up tiny, weak slop. We’re talking swell heights of about 1 ft at best, with short, weak periods around 8 seconds, and combined swell energy is pitiful, reading only 15 on the morning of the 11th. You’d be fightin’ for a knee-high ripple in glassy conditions – not worth wetting a wetsuit for.
Then there’s a brief pulse on August 13th (Thursday). We see a spike in combined energy to 257, with a 5 ft swell from the north, but the period is a poor 7 seconds, so it’s all chop and no power. And the wind is a cross-on from the NNE at 6 mph, so it’ll be messy and blown out. The wave comment says it all: poor surf conditions. That size is right on the edge of being okay for a beginner, but with that onshore wind, it's no good for anyone.
After that, it’s a slow, painful fade. We get glassy mornings and clean conditions, but the swell disappears. August 15th (Saturday) morning offers a whisper of a long-period groundswell from the NNW with a 17-second period, but the height is only 0.7 ft – that’s a lake, not a surf break, with combined energy of just 30. That long period would make it super inconsistent, better suited for a point or reef, but there’s just no size to work with.
From August 17th onward, it’s almost entirely flat, with combined energy readings of zero. There’s a few tiny blips with waves under half a foot on the 21st and 26th, but they’re nothing. It’s a classic case of bad timing – the ocean has just switched off. This is one of those bleak runs where you’re better off tunin’ up your gear and waitin’ for the next system. Keep an eye on the forecasts, though; it tends not to stay this poor for long.
I’d say the closest thing to a standout, and I use that word loosely, is the morning of August 13th. It’s got the biggest combined energy of the whole run (257), but with onshore wind and short period, it’s a "leave it" call. Nothing here is worth burning gas for.

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.
