The Lowdown
Alright, let’s get real about the next couple of weeks at 13th Street. It’s a bit of a scratchy run for most of it, to be honest. We’ve got a lot of small, weak energy and messy winds before things finally line up for a proper session.
The early part, starting Wednesday the 26th, is pretty grim. Swell is tiny, around 2ft to 2ft and the wind is cross-onshore, which is going to leave it lumpy and gutless. The energy is weak, between 130 and 186. Not worth getting wet.
Thursday the 27th through the weekend into early next week stays poor. We’re seeing minimal swell, often under 3ft, with periods that are sometimes short and weak. On Friday the 28th there’s a tiny bump to 2ft from the SSW with a 19-second period in the morning, but the energy is still moderate at best (345 in the morning) and the winds are onshore or cross-onshore. It’s just not going to have any push. Saturday the 29th has a touch more size at 3ft to 3ft with a 16 to 17-second period, energy in the 500s, but again, the wind is spoiling it. It’s a similar story through Sunday and Monday. There’s some energy around, but the quality is just poor. It’s a real test of patience. We’re looking at a whole week with nothing that you’d want to paddle out for.
Now, I’m not going to get too excited, but there is a glimmer on the morning of Thursday the 3rd of September. We finally get a bit of size – 5ft of SSW swell with a 12-second period. But the big one is the wind: it’s glassy. The energy jumps up to 716, which is the strongest we’ve seen. This is your standout window. The conditions look like they could be really clean for a few hours. It’s still a beach break, and the period is moderate (12 seconds), so it might not have the most incredible shape, but that glassy surface is going to make it look a million bucks compared to the last week. The water temp is pretty average for this time of year, so it’s not going to be a huge factor.
After that brief tease, it goes back to the grind. Friday the 4th and the rest of the second week are full of cross-onshore winds and moderate breezes, with the swell dropping back to the 3ft to 3ft range. There’s some energy with periods around 15-17 seconds, but the wind is just going to chop it up. Honestly, after that one morning, there’s nothing else that’s worth getting too amped about. It’s a long, flat, and messy outlook.
I’ll be honest with ya, keep your eye on that Thursday morning. It’s the only true stand-out on offer. For a stretch like this, one good session is all you can ask for.

Information about the 13th Street Surf forecast
The above surf forecast table for 13th Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at 13th Street can be found by selecting the local surf guide option on the grey menu. Our 13th 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 (13th 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 13th 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.
