The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s coming up for 15th Street. Gotta be straight with you – this one’s a tough stretch. We’re looking at a solid 16-day window, but the first two weeks are pretty much a write-off. The water is way warmer than normal for this time of year, sitting at 76°F (anomaly of 8°F), which is very unusual, but unfortunately that doesn’t help the waves.
For the first week, from Saturday, August 1st right through to Friday, August 7th, it’s all poor surf conditions. We’re talking tiny, weak swell – mostly around 1ft to 2ft – with a combined energy that’s struggling to get out of the low hundreds (245 to 463). The winds are a mix of light onshore and cross-onshore breezes, which just leaves the surface bumpy or choppy. Not worth paddling out for.
The second week doesn’t get much better. From Saturday, August 8th to Thursday, August 13th, the swell bumps up just a fraction to 2ft to 3ft, and the energy climbs into the moderate range (314 to 482). But the wind is still mostly onshore or cross-onshore, so the surf stays poor. Still a no-go.
Now, we finally get a little flicker of hope on Friday, August 14th. The afternoon shows a 4ft swell from the SW (period 17 seconds), with a big jump in energy (737). It’s still only rated as marginal – the wind is onshore at 9 mph, so it’s not clean. But it’s the first sign of life. The next day, Saturday, August 15th, morning sees a 3ft SSW swell (16 secs, 518 energy) with a light WNW onshore breeze, and the afternoon lifts to a 3ft SW swell (16 secs, 635 energy) with a light W onshore. Still onshore, still marginal. The best chance for a surfable wave? Probably Saturday afternoon, August 15th, but it’s a long-range call and the wind needs to cooperate. After that, Sunday, August 16th drops back into the poor zone.
So, the honest truth? There’s no standout session here. The whole 16 days is a grind. The only period that even sniffs at being okay is the afternoon of August 14th and the morning/afternoon of August 15th. If you’re desperate, you might get a so-so wave on the 15th, but keep your expectations low. The break is consistent, but the conditions just aren’t lining up. A blank run like this is tough, but forecasts can change. Until then, keep the board in the bag.
Rusty.

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.
