The Lowdown

Alright folks, Rusty here. Let's have a look at what 15th Street is serving up over the next couple weeks.

Right off the bat, Monday the 24th of August is a write-off. The water is sitting at a very unusual 73°, which is much warmer than normal for this time of year, but the surf itself is basically flat with only 2ft of weak, long-period groundswell. You’d be wasting your time.

We’ve got a solid stretch of nothing useful through the rest of the week. Tuesday the 25th sees a little bump to 2ft, but it’s still marginal. Wednesday through Sunday the 30th stays frustratingly small, mostly between 3ft and 4ft. The wind is often a light cross-onshore breeze, which just messes up what little bump there is. The wave energy is moderate at best, hitting around 400-900 (moderate energy), but the quality just isn't there. It’s a long, quiet spell of poor to marginal surf.

Now, hold onto your board. Tuesday, September 1st, is where it finally gets interesting. The morning delivers a clean 4ft swell from the south, and a light cross-offshore breeze from the NNE makes for some proper, clean faces at this beach and reef setup. The period is a modest 12 seconds, but the conditions are there. This is the standout of the whole forecast – a solid, rideable day with decent shape. Keep in mind, it’s a consistent spot that gets crowded often, so get out early.

After that, the surf stays in the marginal range again. Wednesday and Thursday, September 2nd and 3rd, offer 4ft to 5ft, with Thursday the 3rd morning seeing a jump in energy (1212, strong energy) and a long 15-second period from the SSW. It’s another glimmer of hope, but the wind is just onshore or variable, so it’s likely lumpy. The period is long enough (15 seconds) for some grunt, but at a beach and reef setup, it could be closing out too straight.

The second week from the 4th of September onward looks much the same – waist to chest high, with a persistent light cross-onshore breeze. The long period swell from the SSW keeps coming, but the consistency is broken up by wind. If the wind ever turns truly offshore, it could be worth a look, but as it stands, Tuesday the 1st is your only solid bet.

We’ll see what happens – the forecast can change. Rusty out.

A general guide to surfing at 15th Street can be found by selecting the local surf guide option on the grey menu.

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.
