The Lowdown
Alright, Rusty here, let's talk about The Patch.
Right off the bat, the next few days are pretty flat and not worth your time. We’re looking at a real dry spell with nothing decent on the menu until Friday morning, the 18th of September. That’s a solid day and a half of sitting on the beach.
The first real glimmer of hope comes Friday morning. The swell is a tiny 2ft from the SW, but the period is a massive 19 seconds. That’s proper groundswell energy pushing through, and we’ve got glassy conditions. It's a long-period swell, so at a beach setup, it might be a bit straight and fat, but with zero wind and clean lines, it’s a chance to get wet on a longboard. The combined energy is moderate (383).
Honestly, the week is full of marginal stuff until we hit Tuesday the 22nd. That afternoon is the standout of the first week. The swell builds to 5ft from the WNW with a good 12-second period, giving us moderate energy (1039). More importantly, the wind is offshore from the WNW, keeping the surface clean. That’s a solid, fun session for a regular footer.
Then we grind through a few more days of small, cross-onshore junk.
Now, let’s talk about the real meat. Mark your calendar for Wednesday the 30th of September. That morning looks like the absolute best session on offer. We’re talking 8ft of NW swell with a 9-second period. That’s a chunky, powerful wave pushing in with strong wave energy (1608). The wind is glassy – dead calm, zero. That is an exceptional combination for experienced surfers. The same day in the afternoon holds 7ft and clean conditions, but the morning glass is the one. The water temp is about average for this time of year, so a spring suit is the call.
The following morning, Thursday the 1st of October, is also a good one. 6ft from the NW, glassy again, with very good conditions. That’s a fine way to kick off October.
So, to wrap it up: The first week is a slog, but Tuesday the 22nd afternoon is a solid day. For the big guns, the real standout is Wednesday the 30th of September morning. Get on it.
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.
