The Lowdown
G’day, it’s Rusty here.
Honestly, the next couple of weeks are looking pretty grim for a proper surf. We’ve got a long stretch of small, junky waves and onshore winds that will have you checking the forecast more than your board. There’s a real gap in any decent action from now through August 25th. You’ll see a few knee-high blips, but nothing worth paddling out for. Most of this period is just for the die-hards or those happy to get wet without catching much.
The one tiny window where it’s not a complete write-off is the morning of Tuesday, August 18th. It’s still only 3ft of short-period east-southeast windswell, but the wind is dead glassy and the water’s a bit colder than normal for this time of year – about 3° colder than average, so grab the booties. The combined energy is weak at 92, so it’ll be gutless, but at least it’s clean. Freshwater (Northern Beaches) will be the pick, but it’s still very ordinary.
After that, it’s back to the same story. Wednesday, August 19th morning is similar – 3ft and glassy – but again, it’s weak and sickly. The wind swings offshore on Friday, August 21st morning, but the swell has dropped to 3ft and the energy is even weaker at 80. It’s clean but barely breaking.
The real news is late in the window. Around August 26th and 27th, a proper pulse of south-southeast swell shows up. On the afternoon of the 26th, we’re looking at 6ft with a period of 10 seconds, and the combined energy jumps to a strong 516. Unfortunately, the wind is on it, coming from the south and making it choppy and messy. By the morning of the 27th, the swell is still 4ft with a longer 11-second period and energy at 303, but again, it’s cross-onshore and lumpy. This is the most powerful swell of the whole stretch, but the conditions will make it a tough, drifty session at best. For the experts only, and it’s not going to be pretty.
So, there you have it. A couple of clean but weak mornings early on, and a bigger but messy pulse at the end of the month. Don’t get your hopes up for anything epic. If you’re desperate, the glassy windows on the 18th and 19th are your best bet for a few gutless ones. Otherwise, wait for the winds to drop and look for a bank elsewhere.
Rusty.

Information about the Freshwater and Harbord Surf forecast
The above surf forecast table for Freshwater and Harbord provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Freshwater and Harbord can be found by selecting the local surf guide option on the grey menu. Our Freshwater and Harbord 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 (Freshwater and Harbord) 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 Freshwater and Harbord 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.
