The Lowdown
Alright, Rusty here again. Let's get into what's on the table for 15th Street.
Honestly, mate, the next two weeks are a bit flat. There are waves on offer, but for the most part, it’s going to be marginal. The real standout moment looks like it’ll hit us on Wednesday, September 2nd. That morning has got some real potential, but you'll have to wade through a lot of average days to get there.
Starting off, the forecast kicks in on Thursday, August 27th. It's small, weak stuff with a south swell coming in at around 4ft, period around 12 seconds. The wind is a light cross-onshore, so it's not terrible, but the energy is low (582). Not worth rushing out for.
Friday the 28th sees a bit more character. The swell drops to around 2.5ft, but the period jumps to 16 seconds – that's a proper groundswell. You'll get longer waits between sets, and it might wall up a bit at the beach break. The wind is actually offshore in the morning with a WSW breeze, so it'll be clean. The energy is still moderate (501). It’s rideable, but small.
Saturday and Sunday, the 29th and 30th, are similar. Swell hanging around 3 to 4ft from the SSW with periods around 14 to 16 seconds. The wind is inconsistent, flicking between cross-on and onshore. The energy picks up a bit on the Saturday arvo (887), but the quality isn't there. It's a bit choppy. Monday the 31st is much the same story, westerly winds keeping it clean-ish, but the swell lacks any punch.
Now, Wednesday, September 2nd. This is the one. The morning goes glassy. Dead calm, zero wind. The swell bumps up to around 4.5ft from the SSW with a 12-second period. The combined energy is a solid moderate 748. That glassy morning window is your ticket for clean, fun waves. It won't be huge, but for the quality, this is the best session of the fortnight.
The rest of the first week into September gets a bit bigger, but the wind and quality aren't there. The 3rd sees 6ft swell, but with onshore wind. That’s getting a bit much for beginners, and it’s just messy. The 4th and 5th drop back down to around 4ft, with better period around 17 seconds, but the wind stays unfavourable.
The second week, from the 7th to the 11th of September, is pretty grim. Swell stays under 3ft mostly, with a lot of cross-shore and onshore wind. The occasional clean window shows up, like Monday the 7th afternoon with a cross-offshore breeze from the NNE, but the swell is only around 3ft. There’s a bump on the 10th afternoon with about 3ft swell from the SW, and on the 11th morning it's tiny but glassy with a light westerly. Nothing to get excited about.

Information about the 15th Street Surf forecast
The above surf forecast table for 15th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 15th Street can be found by selecting the local surf guide option on the grey menu. Our 15th Street 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 (15th Street) 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 15th Street 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.
