The Lowdown
Rusty here again. Let’s talk about The Harbour. This 16-day stretch is a total bust. There’s nothing worth paddling out for. The swell is tiny, the energy is flat, and the conditions never line up.
We kick off Sunday the 13th with a glassy 0.2m SSE swell, but the combined energy is only 2 – it’s just a ripple. The wind goes side-off in the afternoon, but the swell doesn’t show up. Monday the 14th and Tuesday the 15th are the same: tiny, poor surf, with the energy never hitting 30. Wednesday the 16th brings a 0.8m NNW swell at 4 seconds, but it’s cross-shore wind with a fresh breeze, making it lumpy and choppy. No good.
The middle of the week from Thursday the 17th to Saturday the 19th is flat or barely a ripple, with some offshore winds, but no swell to work with. Sunday the 20th is more of the same – 0.2m SSE at 6 seconds, weak energy of 3 or 4. Then Monday the 21st we get a brief pulse: 0.9m SSE at 6 seconds, with a combined energy of 55, and fresh offshore wind from the SW. That’s the closest thing to a highlight, but it’s still a poor surf condition for a beach/groyne setup. It just doesn’t have the size or period to make it worthwhile.
After that, it’s flat again or tiny wind slop right through to Monday the 28th. The water temp is 14°C with a 0.9° anomaly, which is pretty average for this time of year – no surprise.
Honestly, this stretch is a blank run. The Harbour is usually fairly consistent, but the forecasts just aren't putting anything together. It’s one of those periods where you’re better off doing something else. Keep an eye on it, though; it tends not to stay this poor for long. Forecasts can change.
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.
