The Lowdown
Alright, Rusty here. Let’s take a look at what’s on offer for Freshwater and Harbord over the next couple of weeks.
Honestly, it’s a pretty grim stretch. We’ve got a long run of days where the conditions just aren't coming together for a decent paddle. The water’s sitting at 63°F which is about average for this time of year, so nothing unusual there but not much else to get excited about.
The whole outlook is a real test of patience. From Tuesday the 18th to about Monday the 31st of August, it’s mostly small, weak, and messy. The combined swell energy barely nudges above 100 for most of that time – we’re looking at a lot of readings in the low double digits, which is barely a ripple. Winds are all over the shop, mostly cross or cross-on, with only a few brief windows of clean conditions but no real swell to work with. On Wednesday morning the 19th, it’s glassy with a tiny 3ft ESE swell, but it’s only 7 seconds period and the score is a dud. Thursday the 27th afternoon shows a moderate offshore from the WNW, but the swell is only 3ft from the NE – surfable but flat-looking.
The one true standout comes much later. Keep your eye on Monday the 31st of August in the morning. Freshwater picks up a 1ft SSE groundswell with a very long period of 15 seconds, and the combined energy jumps to 104 – moderate wave energy. The wind is light cross-off from the NE, so it’ll be clean. It’s small, but that long period means it’ll have some shape, especially on the peak. Best for a log or a longboard.
Then, Tuesday the 1st of September morning is the next interesting window. It turns glassy with calm winds, and the swell bumps up to 4ft from the SSE with a 10-second period. Combined energy hits 239 – solid moderate energy. It’s small but clean, and likely the best conditions of the whole outlook for a fun, uncrowded session. The direction is close to the optimum ENE for the break, so it should work. Crowds are “often” here, but for a Tuesday morning with nothing special on the charts, you might get lucky.
After that, it fades again. The second week looks pretty quiet, with no other real standouts.
So in short: you’ve got a long flat spell, then a small but clean window right at the end of the month into early September. The water’s average temp, the swells are small. If you’re keen, pencil in the 31st of August morning and the 1st of September morning for the cleanest little rides on offer.
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.
