The Lowdown
Alright, folks, Rusty here. Let’s cut to it: the next couple of weeks at 15th Street are looking rough for a real surf. There’s some swell coming, but the quality just isn’t there.
The first real surf shows up on Thursday, July 30th. We’ve got a solid groundswell from the SSW, 3 ft at a very long 16 seconds. That’s a lot of energy in the water (787), and the water is feeling much warmer than usual for this time of year at 76°. But the wind is onshore from the W at 9 mph, and the report says it’s marginal. It’s going to be choppy and not clean.
Friday the 31st has a slightly bigger swell, 4 ft from the SSW, but still with that onshore wind. The energy drops a bit (655), but conditions are still poor. By Saturday and Sunday, the swell fades to 2 ft – 2 ft, and we’re stuck with cross-onshore winds. It’s small, bumpy, and not worth getting wet for.
From the 1st of August right through to the 14th, it’s a long, flat stretch. Days of tiny waves, weak energy readings (often under 300), and a persistent onshore or cross-onshore breeze. The swell barely gets above 3 ft, and the periods are all over the place. This kind of blank run is normal for this area.
If you’re itching for a paddle, there’s a glimmer on Friday, August 7th, in the morning. A 3 ft swell from the SSW with a very long period of 19 seconds. That’s proper groundswell energy (579), with the wind still onshore. It’s the highest energy we’ve seen in a while, but the report says “marginal” – so don’t expect perfection.
Another faint flicker is on Wednesday, August 12th, in the afternoon. A 3 ft swell from the SW with a 16-second period and moderate energy (523), again flagged as marginal. The wind is onshore from the W. It’s the best of a bad bunch.
The Bottom Line: The best bet in this whole 16-day window is the morning of Friday, August 7th. It’s the most energy we’ll see, and the long period means there’ll be some push, even if the wind messes it up. For the rest… save your wax for another time.
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.
