The Lowdown
Alright, Rusty here, let’s break down what’s heading our way for Freshwater and Harbord.
Honestly, the first week and a half is a dead zone for decent surf. From the 14th all the way through to the morning of the 23rd, it’s mostly tiny, onshore junk or flat spells. There are a couple of moments, but nothing to get excited about.
The one morning that stands out is Saturday, September 19th. A long-period groundswell from the SSE, only about 1ft, but with an 18-second period. That energy is real—combined energy around 108, moderate, but with a light, clean cross-off breeze from the WSW, conditions will be glassy. This spot is sheltered and prefers an ENE swell, so the direction isn’t perfect, but for this break, that’s the best you’re gonna see. It’s a consistent, beginner-friendly spot, so beginners, this is your window.
Next up, the morning of Tuesday, September 22nd: a 4ft SE swell with a 7-second period, combined energy at 112, and a clean cross-off wind from the NNE. It’s surfable, but the quality is still just okay.
From the 26th onward, the swell gets bigger—up to 6ft on the afternoon of the 28th (combined energy 345, strong)—but the wind is a mess, mostly strong cross-shore or onshore. That kind of size with messy wind is for experienced surfers only, and even then, it won’t be pretty.
Water temp is about average for this time of year, nothing weird going on.
So, if you’re keen, pencil in the 19th. That’s the clear winner. Otherwise, it’s a waiting game.
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.
