The Lowdown
Righto, Rusty here. Let’s have a look at what Freshwater and Harbord have got cookin’ for us over the next couple of weeks. I’ll be straight with you—this stretch is lookin’ pretty flat and disappointing for the most part.
The first solid gap is a long one. From now through Thursday, September 17th, it’s near enough to a write-off. Tiny scraps, onshore or cross-shore winds, and just no grunt in the water. You’d be paddlin’ for puddles. The water temp is sittin’ around 63°, which is about average for this time of year—nothin’ to get excited about, but not a shock to the system either.
Friday, September 18th shows the faintest glimmer of life. The morning brings a little 4 ft swell out of the SE, with 7-second period and a clean cross-off breeze from the NNW. The combined energy’s sittin’ at 129—moderate, but it’s the first real pulse we’ve seen. Still, the quality’s only just surfable, nothin’ to write home about. By afternoon, the onshore NE wind messes it up again.
Saturday, September 19th morning has a touch more promise—3 ft from the ESE but with a longer 11-second period, givin’ the waves a bit more push and shape. Combined energy hits 198 (moderate), and with that light W wind bein’ cross-off, it’ll be clean. For a sheltered beach setup like Freshwater, this is the best on offer. The swell direction ain’t perfect for the optimum ENE, but the bigger period and clean conditions make this a standout for a quiet, cruisy session. Expect a few others out there though—crowds are often around here.
After that, it fades again. A few more flat, windy days creep in. Nothin’ of substance until Friday, September 25th morning, when a 4 ft NE swell with a light offshore NNW breeze and combined energy of 181 pops up. It’s just “surfable” again—not epic, but if you’re desperate, that’s your window. Saturday, September 26th morning turns glassy with a 3 ft NE swell, but the energy’s only 99, so it’ll be weak and small.
Honestly, over the 16-day window, there’s no real pumpin’ swell. The standout is Saturday the 19th morning—clean, longer period, and just enough energy for a fun little session. Everything else is lean pickin’s. Keep the hopes modest, and check back next week—forecasts can change.
Rusty.

A general guide to surfing at Freshwater and Harbord can be found by selecting the local surf guide option on the grey menu.

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.
