The Lowdown
Right, let’s have a look at what we’ve got for the next couple of weeks. The only spot on the cards is Yo Yo's-The Wedge, a heavy reef that’s strictly for advanced crew. This is an exposed, very consistent slab that picks up swell from the south-west – exactly what the file’s hoping for. Water temp is sitting at 79°F with an anomaly of -1°F, so pretty average for this time of year, nada weird going on.
The pattern kicks off Tuesday the 15th with a good-sized SW swell pushing 6ft, period a solid 15 seconds – proper groundswell. But the wind is howling from the SE at 16 mph, cross-off which keeps the face clean, but it’s a fresh breeze. Combined wave energy is strong at 1540. It’s rideable but not the best. Wednesday the 16th looks a touch cleaner early with wind dropping to 9 mph, still cross-off, swell hanging around 6ft from the SW, 15-second period, energy still strong at 1306. That morning window is the pick of the first few days – clean lines for the experienced. Thursday the 17th pushes up to 7ft from the SSW, period 14 seconds, but the wind goes cross, creating a bit of a cross-chop in the morning. Energy jumps to 1712. It’s a bit messy but still powerful.
Friday the 18th eases back to 5–5ft, but the afternoon gets a nice light SE cross-off breeze at 6 mph, clean conditions with energy around 875. Not massive but clean. Saturday the 19th is smaller, dropping to 4ft, lighter cross-on winds in the morning, not worth getting too excited about. Sunday the 20th brings a nice pulse: 6–7ft from the SW, period stretching to 16 seconds, energy hitting 1962 in the morning and 2253 in the afternoon. Winds are cross-off in the arvo, so that Sunday afternoon looks like a proper standout – clean, strong, long-period groundswell. Monday the 21st stays solid at 6ft but the morning is a bit chop-styled with cross winds.
Now, here’s where it gets interesting. A gap of small, so-so surf runs from the 22nd to the 25th – waves around 4–5ft, nothing special. But hold onto your board, because Saturday the 26th of September fires up. Swell jumps to 10ft from the SSW, period a massive 21 seconds, combined energy absolutely thumping at 7182 in the morning and peaking at 8297 in the afternoon. Winds are cross-off from the SE at 9–12 mph, clean as a whistle. This is exceptional, expert-only territory – that is the clear standout of the whole run. Sunday the 27th holds at 10ft, period drops to 17–18 seconds, still huge, energy still well above 4000, and winds stay light offshore/cross-off. Monday the 28th eases to 7–7ft, still a strong SSW groundswell, but the morning has a bit of cross-chop. After that, the week trails off into the 5–6ft range, clean but nothing that’ll make you skip work. The 30th has a solid 6ft SSW swell, 16-second period, cross-off winds – a decent end to the outlook.
Bottom line: the one and only true standout is Saturday the 26th of September – massive 10ft SSW groundswell, super clean, expert-only slabs. Sunday the 27th is also there for the brave. Sunday the 20th afternoon is your best earlier call for cleaner, powerful waves. Crowds are often a thing here, so expect company.

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