The Lowdown
Alright, Rusty here. Let’s break down what’s happening at The Patch.
We’ve got some small, clean surf coming up over the next couple of weeks, but it’s not going to be pumping every day. There are a few windows where everything lines up, especially early on and then again later. Water temp is 61°, which is a touch warmer than normal for this time of year—nothing extreme, just a bit of extra warmth.
The first standout is Saturday, August 29th, in the morning. The Patch is looking clean with a 3ft swell from the SW and a very long period of 18 seconds. That’s proper groundswell, and with a light cross-offshore breeze from the WNW, the waves will be smooth. Combined swell energy is 802 (moderate), so there’s enough power to keep things interesting. This is a good one for beginners given the size. Crowds can show up sometimes.
Saturday afternoon stays clean but the wind picks up and the swell drops a little. Sunday the 30th is more onshore and choppy, so not a great call. Monday and Tuesday are pretty poor—small and weak.
The next real highlight is Thursday, September 3rd, in the morning. Again, clean conditions with a 3ft SW swell, 14-second period, and light cross-off wind. Energy is 543 (moderate). Not big, but fun.
Friday, September 4th, morning is also clean with a 3ft SW swell, 18-second period, and light cross-off wind. Energy is 841 (moderate). The afternoon jumps to 4ft from the WNW but with a short 10-second period and stronger wind—still cross-off, but less appealing.
Saturday, September 5th, morning is a beauty. Glassy conditions, 3ft SW swell with a 16-second period, and light wind. Energy is 663 (moderate). This is the morning you want to be in the water.
After that, the surf fades again. The second week has a few clean mornings, like Thursday, September 10th, and Friday, September 11th, but the swell is smaller—around 2ft to 3ft—and energy is lower. Still worth a paddle if you’re keen.
The very end of the forecast, Sunday, September 13th, afternoon, shows a bump to 6ft from the WNW but with a short 6-second period and onshore wind. That’s messy and bumpy—better for kite surfing than paddle surfing.
Overall, the first Saturday and the following Saturday morning are your best bets. Everything else is small or a bit messy.
Rusty.

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