The Lowdown
Alright, let’s break it down. The Harbour is the only game in town for this 16-day stretch, and I’m not gonna sugarcoat it – it’s a rough go. We’ve got a long gap of flat or near-flat, poor-quality surf from now straight through the end of July. There’s hardly a bump worth paddling for, with the combined energy of all swells directed here sitting at zero or single-digit numbers for days on end. The water temperature is 57°, which is about average for this time of year, so nothing wild there, but it won’t help when there’s nothing to ride.
We finally see a glimmer on the morning of Tuesday, August 4th. The Harbour (beach/groyne) picks up a 6ft swell from the NE, with a period of 6 seconds – that’s short-period, so it’ll be a bit disorganized and lack the grunt of a real groundswell. The combined energy hitting the coast is 238, which is solid moderate energy, and with a moderate offshore wind from the SW, it’ll be clean. This is the one real highlight of the whole forecast, but it’s a long way off. The swell is just over 5ft, so it’s pushing into intermediate territory – not for beginners, but doable for those with some time in the water. The offshore wind will keep the faces smooth, and the beach/groyne setup should offer some workable peaks. Keep in mind it’s fairly consistent here, so when it’s on, it’s on, but that short period means the waves won’t have much gap between sets.
The rest of the window? Bone dry. From now until that August 4th event, there’s a solid two-week stretch of nothing worth your time. The afternoon of the 4th drops off completely again, with only a tiny 1ft leftover. We’ve got a few clean windows with light offshore or glassy conditions earlier on, but with no swell to speak of, it’s just a flat, pretty lake. This is one of those blank runs that’s more normal for the area – the forecasts can change, but right now, it’s a waiting game.

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.
