The Lowdown

Alright, this is Rusty coming to you from the sand. Let's be real, 15th Street is feeling a bit flat and lackluster for the next week. We’ve got a long stretch of poor conditions ahead of us before things start to look interesting.

We're kicking off on Thursday the 10th with a pretty weak show. The surf is small, around 3ft, coming from the SW. The wind is a cross-on, making for a choppy, messy surface. The overall energy is moderate at best (632), and the water temp is a touch warmer than normal at 71°, which is a couple degrees above average. Honestly, it’s not worth paddling out for.

Friday the 11th and Saturday the 12th look even worse. The swell drops a bit, the wind stays messy, and things get pretty grim. Expect small, weak waves and poor quality. It’s a write-off. We’ll have to sit through a dry spell of about seven days before anything decent starts to form.

Now, after that long wait, things start to look up. The real standout action is happening way out on Saturday the 19th. On the morning of the 19th, we see a 3ft SW groundswell with a very long period of 18 seconds. The combined energy will be solid (626), and the wind is only a light cross-on, which should keep the surface relatively clean. This is a classic longer-period groundswell, which will be better for an exposed point or reef than a beach break, but the quality of the swell is definitely there. It's a hopeful sign. We then see a similar setup on Sunday the 20th morning, with a 3ft SW swell, again a long 18-second period, and even more energy (688) with light wind. That Sunday morning is the best bet of the whole run.

The energy then picks up even more going into Monday the 21st with a 4ft SW swell (705 energy) and offshore wind. It will be clean, and the size is still manageable for most surfers. The following Tuesday the 22nd continues the trend with 3ft SW swell and clean, glassy-looking conditions (offshore wind). It's a shame it took so long to get here.

Beyond that, we get a bit of a pulse on the 25th of September with a tiny 2ft SW swell but with a very long 21-second period. The energy is decent (668), but the size is small so it’s a tricky one for the experts only.

In short, don't get your hopes up for the next week. It's a total dud. But if you can wait, the weekend of the 19th and 20th (especially Sunday the 20th) and the start of the following week (the 21st and 22nd) look promising with clean, long-period groundswell. It’s not going to be huge, but it should be a fun, clean ride.

Rusty.

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.
