The Lowdown
Alright, let’s put it in feet and miles per hour.
Look, The Harbour is in a rough spot. We’ve got a long dry spell of flat to junk surf for the first week and then some, so don’t get your hopes up until Thursday, August 27th rolls around.
Tuesday the 18th starts off with a tiny 1ft swell from the ENE, period a short 5 seconds, and a cross-on wind from the NNW at 6 mph. Energy is weak, barely a bump. Water temp is 57°, normal for this time of year. It’s poor, not worth the walk.
From Wednesday the 19th all the way through Tuesday the 25th, it’s basically a gap. You get glimpses: 0.7ft, 1.0ft, even 2ft on Saturday the 22nd, but the wind is cross or cross-on, blowing 15 to 19 mph, messy and lumpy. Sunday the 23rd goes clean with light offshore wind from the WSW, but there’s zero swell to ride. Clean and flat — that’s the story.
Come Thursday the 27th of August morning — this is your bright spot. A 3ft swell from the ESE, period 7 seconds, with a clean cross-off wind from the SSE at 12 mph. Wave energy hits 139, so there’s some moderate push. It’s clean, it’s rideable. Not epic, but it’s as good as it gets. That afternoon, the wind swings NW and goes cross, the swell stays around 3ft but energy drops to 77 and it gets a chop.
Friday the 28th morning has 2ft from the ENE, clean but the wind is strong from the SSE at 22 mph. Saturday the 29th morning is the next option — 3ft from the ESE, offshore WSW wind at 22 mph, fresh but clean. Energy is 84. Maybe a dawn patrol.
The rest — Sunday the 30th, Monday the 31st, into September — is all small, under 2ft, with offshore or cross-off wind but no power. Tuesday the 1st of September morning has the biggest number at 4ft from the S, but it’s blowing 28 mph from the SSE, clean but strong. Energy is 92.
No true standout here. Thursday the 27th morning is the pick. The rest is for rigging your kite or staying in bed.

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.
