The Lowdown
Alright, Rusty here. Let’s have a look at what’s cookin’ for our stretch of coast.
Truth be told, we’re looking at a pretty quiet start and a long, frustrating run of nothing much. The first real chance of anything decent is still a week away, on Tuesday the 25th of August, and even that is a bit of a mixed bag. Before that, from Wednesday the 19th right through to Monday the 24th, it’s mostly small, weak, and messy. We’re talking tiny waves with poor conditions – lots of ordinary surf and not worth paddling out for.
Now, on Tuesday the 25th, things finally wake up a bit. The morning sees a pulse of 6ft from the NE, pushing combined wave energy up to a solidly moderate 546, but it’s still not great for quality, with messy cross-off winds. That afternoon, however, the wind goes dead calm – glassy – and the swell drops to 4ft from the NE. That afternoon window is your only real chance to get something clean and rideable, but it’s still just ordinary surf.
Later in the week, there’s a bit more promise. On Friday the 28th, we get a clean 5ft SSE groundswell with a 9-second period. Both morning and afternoon have light or glassy winds, making for clean conditions. Wave energy is moderate (361 to 384). It’s not a standout power day, but given the dry spell, it’s the best on offer.
The real standout, if you’ve got patience, lands on Tuesday the 1st of September. We’re looking at a 5ft SE groundswell with a 12-second period – that’s proper long-period groundswell energy, delivering a strong 728 in combined wave energy. The sets will have some real punch. Freshwater will pick this up nicely. That swell direction (SE) is a solid match for the break’s optimum ENE. The morning has light onshore winds and rain showers, so it’s not perfect, but the size and power make it the most interesting surf of the whole 16-day window. Just be aware that longer-period stuff like this can throw closeouts at beach breaks, but given the size, it should offer some solid peaks for experienced surfers.
Water temperature is 63°, which is about 2° cooler than average for this time of year – nothing unusual, just your standard winter feel.
So, to wrap it up: don’t bother paddling out until Friday the 28th for a clean but average session. The real one to circle is Tuesday the 1st of September – that’s your best bet for some punchy, meaningful waves, even if the wind isn’t perfect. Keep an eye on it, but for the next week, save your energy.

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.
