The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the table for the next couple of weeks.
Honestly, I'm looking at a pretty grim picture. The whole 16-day window is going to be a complete write-off for any kind of decent surf. There's not a single session that's worth paddling out for. The forecasts are all coming back with "poor surf conditions" stamped on them, and that's the truth of it.
Right from the start, Friday the 31st of July, we've got a little swell of 3 ft from the SSW, but it's onshore, messy, and the combined energy is a weak 431. The water is a warm 76°F, which is a whopping 8°F warmer than usual for this time of year, but that's small comfort when the waves are junk.
We roll into August, and it's more of the same. Swell stays tiny, mostly under 3 ft, and the wind is almost always onshore or cross-onshore from the W or SW. It's a heartbreaking run of glassy or light breeze days all going to waste because there's just no power in the water. The period is decent, sometimes 14 or 15 seconds, but that long-period groundswell is hitting a beach-and-reef setup with no real angle, so it's just straight and weak.
The second week doesn't get any better. We're looking at a solid two-week stretch of nothing. From the 7th of August right through to the 15th, the swell height never gets over 3 ft, and the wind still refuses to play nice. The combined energy values do push up into the moderate 400s and 500s, but it's all noise and no shape. The swell is all from the SW or SSW, which is the optimum direction for this spot, but it's just not got any size or punch to it.
So, what's the call? There are no standouts, no hidden gems, nothing. 15th Street is a consistent spot, so it's unusual to see such a long, blank run. It won't stay this poor forever, but for now, you're better off leaving the boards in the shed. The wind and the swell are just a bad match for paddling, and honestly, with that consistent onshore flow, it might be a better setup for the kite crew than anyone with a paddle.
Rusty.

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.
