The Lowdown
Alright, I’m Rusty, and I’ve looked at the numbers for your local stretch.
Well, I’ll be honest with you, it’s a pretty bleak start. The Harbour (beach/groyne) is showing next to nothing for the first ten days of September. We’re looking at a solid gap of flat, poor conditions through until the 10th. A few little bumps show up on the 3rd and 4th, but with tiny swells and messy wind, it’s not worth paddling out for.
The first real sign of life arrives on Friday the 11th. The morning session is glassy, with a 4ft swell from the north. It’s short-period windswell, so not a lot of grunt, and the combined energy is weak (100). It’s surfable, but ordinary. The water is sitting at 57°, about average for this time of year.
The standout period, and the one to circle on your calendar, is the weekend of the 13th and 14th of September. Sunday morning the 13th is looking choice: glassy conditions, 6ft swell from the SSE, with moderate wave energy (213). By the afternoon, it jumps to 8ft from the SSE, and the energy is strong (487). That’s a serious step up. The wind stays clean, so you’re looking at proper, surfable waves. It’s big enough that beginners might want to sit this one out, but for the intermediate crew, it’s game on.
Monday the 14th follows up nicely. Glassy start with a 6ft SE swell and strong energy (295), then the afternoon cleans up with a 5ft SSE swell (417). The wind is either glassy or light offshore, which will keep the surface smooth.
After that, the energy drops off again, with Tuesday the 15th showing a drop to 4ft and weak energy (85), and it’s all downhill from there into the rest of the week.
So, the long and short of it: you’ve got a lot of flat, quiet days to get your gear sorted. The real action kicks off on Sunday the 13th and Monday the 14th. That’s the window. The swell direction is a touch south of the optimum SE, but with glassy and clean winds, The Harbour should be working nicely. Expect some company – it’s a spot that does get crowded sometimes, especially when it’s good.
Rusty.

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