The Lowdown
Alright, let's get real about the next couple of weeks for The Harbour. It ain't pretty. We are looking at a long stretch of flat, messy conditions, so don't get your hopes up for any kind of proper session.
The water temp is about 57°, right on the money for this time of year. So, that's one thing we don't have to worry about.
This Saturday afternoon (the 15th) is tiny, a weak 0.3ft swell with a short period. Not worth the paddle. After that, we're in for a real dry spell. From Sunday the 16th through Wednesday the 20th, there's nothing on the cards – zero wave energy. The wind is sometimes light or glassy, but with no waves, it's a flat, lifeless ocean.
We get a couple of little bumps around the 18th and 19th, but they’re nothing. Weak energy (6) and (3). Just enough to maybe push a little foam onto the shore. Then from the 20th to the 23rd, the wind goes strong from the NNW, making things choppy and ugly. This is more kite-surfing wind and chop than anything for a surfboard.
There's a brief moment on Monday the 24th with glassy conditions and a 1ft NE swell, but it's weak (2). The swell tries to build a touch on the 25th and 26th, up to 1ft from the NE, but the period is short and the wind is onshore or side-onshore. It's going to be a mess.
The last day of the month, the 30th, shows a pulse from the SSE at 1ft (8), but a fresh cross-shore wind will tear it apart.
Look, there's no standout day in this whole 16-day window. The Harbour just isn't picking up these weak, short-period pulses. It's a waiting game, for sure. But the plus side is, a break this exposed doesn't usually stay this flat for long. Forecasts can change, and we'll be watching for that. Stay tuned.
Rusty out.

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.
