The Lowdown
Alright, Rusty here. Let's have a look at what The Harbour has in store for us over the next couple of weeks.
Look, I gotta be straight with you. The next week is a real struggle. We’ve got a long, dry spell of nothing but lousy surf conditions from now through to the 18th of September. The swell is either non-existent or just too small and weak to bother with, and the wind is mostly a messy cross-off. You’ll see a few tiny waves pop up, like a 0.7ft ripple on Sunday the 13th with glassy conditions – but that’s barely a knee-high slosh. It’s gonna be a frustrating wait.
The real standout, and I mean the *only* one worth circling on the calendar, is Sunday the 20th of September. The Harbour is set to see a solid 10ft swell rolling in from the SSE, and that’s packing some serious energy, with a combined energy reading of 956 – that’s strong stuff. The wind is a cross-off from the West. Now, a fair warning: this much power is going to make it a heavy, expert-only session. The wave comment even says the swell is predicted to be too big for this break, so if you’re not a seasoned surfer, give it a miss. For the experienced crew, it could be a wild one, but the conditions are clean.
After that buzz on the 20th, it’s back into the quiet zone. Monday the 21st offers a pathetic 1.0ft with an offshore wind, but the energy is a weak 12. From there, we’re looking at empty lineups and flat spells all the way to the end of the forecast on the 27th. There’s a last gasp on Sunday the 27th with a 3ft swell and a strong offshore wind from the WSW, but even that’s tricky to paddle into. The water temp is sitting around 56°F, which is pretty normal for this time of year, nothing unusual there.
To put it bluntly: hold out for the 20th if you want some size and power, but keep your expectations in check after that.
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.
