The Lowdown
Alright, Rusty again. Same story, different units.
To be straight with you, The Harbour has a long, dry spell ahead. It’s a beach/groyne break, fairly consistent, but everything is working against us for the next sixteen days. Water temp’s sitting around 57°F, which is about what you’d expect for this time of year.
Let’s start on Thursday the 13th of August. A small 3-foot SE swell rolls in with a short 6-second period, energy is just 60 (weak), and the wind is a 6 mph cross-off from the south. It’s clean in the morning, but the call is poor surf all the way. That afternoon the swell packs up and we get rain, so no dice there.
From Friday the 14th right through to late August, it’s dead or ugly. Saturday the 15th barely registers a 0.7-foot wave with 4 seconds of period, energy at 2. It’s glassy, but there’s nothing to catch. The 16th and 17th are flat calm with glassy conditions, but zero waves. By Tuesday the 18th we get a 2-foot swell from the SSE, but the wind turns onshore from the NE at 3 mph, and it just won’t hold. By the 25th, the swell bumps up to 3 feet from the east, period up to 7 seconds, energy hits 146 (moderate), but the wind is screaming from the NNE at 15 mph, cross-onshore. It’s choppy and lumpy. If you’ve got a kite, you might have fun, but for a paddle surfer, it’s no good. Wednesday the 26th gives us 4-foot waves from the NE, energy up over 200 (strong), but again, winds are cross-onshore or onshore, ruining any chance of shape.
The only time you might get a wave is Thursday the 27th of August. A glassy morning with a light SSW breeze, 3-foot swell from the NE, period 8 seconds, and energy at 108 (moderate). It’s called “surfable” but ordinary. That’s the best we get—a single morning after a two-week drought. That afternoon sees the cross-on wind come back and kill it. After the 28th, it flatlines again.
So yeah, it’s pretty grim. If you’re desperate, the 27th of August morning is your window. Otherwise, don’t bother packing the board just yet.
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.
