The Lowdown
Alright folks, Rusty here. Let's have a look at what's on offer for the next couple of weeks.
To be straight with you, the outlook for 15th Street is pretty grim for a long stretch. The first real chance to even think about paddling out doesn't show up until late in the period. From Wednesday, August 5th all the way through to the afternoon of Thursday, August 13th, we are looking at poor surf conditions. The combo swell energy is weak to moderate, with values between 143 and 757, but the waves are just too small and weak to get excited about, and the wind is frequently cross-onshore, messing up any chance of a clean face. I'd call that a solid week-plus of nothing doing.
The water temp is about average for this time of year, so nothing wild there.
Things start to get a little more interesting around Friday, August 14th. The afternoon shows a bit of a pulse with a 3ft SSW groundswell, period at 18 seconds, and the combined energy hitting 757. That's a long period for a beachy setup, which can mean the waves break a bit too straight and fat, but the wind is light and offshore from the W at 6 mph. That's clean. It's still a marginal call, but it's the best we've seen in a while.
The standout for the whole 16-day window? I'd put my money on Saturday, the 15th of August. The morning sees 3ft SSW swell with a 16-second period and combined energy of 650. The wind is light and offshore from the W at 9 mph. That's prime conditions for a beach break – clean, glassy faces. The afternoon steps it up a notch with the swell hitting 4ft from the same direction, period holding at 16 seconds, and the energy jumping to 732. Wind stays light and offshore. It's still a marginal rating, but if you pick your tide, this could be a fun session. Just be aware it's a long-period groundswell, so it might be a bit fat and need a bit of patience. If you're a beginner, that 4ft might be a little punchy for you.
Sunday the 16th still has some 3ft swell in the morning with offshore wind, but it drops off a bit after that.
So, the long and short of it: you've got a whole lot of waiting for a couple of days that might just be worth it. Aim for the 15th. Keep an eye on the tides.
Rusty.

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.
