The Lowdown
Well, mate, it’s been a real drought around here. The Harbour (beach/groyne) has been sitting flat or offering nothing but wind chop for the better part of the last week and a half. From Sunday 30 August right through to Wednesday 9 September, every session’s been marked “poor surf conditions” – no real rideable waves, just tiny slop or cross-onshore junk. The water temp’s sitting at about 57°, which is pretty average for this time of year, so nothing special there.
Then, just when you’re about to give up, Thursday 10 September rolls in with a late-summer surprise. The morning is the real standout: a clean 6ft swell out of the SSE – that’s close to the optimum SE direction for this break – with a short period of 6 seconds, so it’s more windswell than groundswell. The combined energy is moderate at 296, and the wind goes dead calm, glassy. That means smooth, clean faces. It’s not beginner-friendly at that size (over 5ft), but solid for intermediates. The afternoon keeps it going: 6ft, still SSE, period 7 seconds, combined energy 241, with a cross-off breeze cleaning it up further. Still good, though not as pristine as the morning glass.
After that, it’s back to nothing. From Friday 11 September onward, you’re looking at flat spells, tiny bumps, or onshore slop. The whole 16-day window basically gives you one good day – if it holds. Long-range, that Thursday morning is promising but keep your expectations in check; things can change. If you’re keen, be there early on the 10th and make the most of it.

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.
