The Lowdown
Alright folks, Rusty here. Look, I’m gonna be straight with you – this stretch we’re looking at is a real flat spell. The swell energy is weak, barely cracking 200 to 300 in the combined energy bracket, and it’s all short-period, choppy mush. Don’t get your hopes up.
The first surfable recommendation doesn’t kick off until Friday morning, 31 July. We’ve got a clean 4 ft SSW swell rolling in at 14 seconds, with a light 6 mph W wind blowing straight onshore. That’s small and soft, but with the wind being light, it’s the best we’ll see for a while. The combined energy is moderate at 655, so there’s a little bit of push. The water temp is about average for this time of year.
That little pulse fades fast. By afternoon it drops to 3 ft and the wind swings to WNW, still light but cross-onshore, making it crumbly and inconsistent. From Saturday 1 August all the way through to Thursday 13 August, it’s a grim run of poor surf conditions. Swell heights barely reach 2 ft, periods are short, and the wind is either cross-onshore or onshore with a gentle breeze. The waves are too weak to ride, messy, and you’d be fighting chop. The combined energy is weak, staying under 300 for days.
There’s a tiny flicker of hope on Wednesday 12 August afternoon, when the swell bumps up to 3 ft from the SW with a 16-second period, and the combined energy hits 574. The wind is light and onshore, which is the best we’ve had in a while. It’s still marginal, but it’s a slight improvement. Then Friday 14 August morning and Saturday 15 August morning show similar 3 ft SW/SSW swell with moderate energy, but again, the wind is onshore or cross-onshore, so it’s going to be lumpy and hard to get a clean ride.
Honestly, the standout is that Friday 31 July morning. That 4 ft swell with light onshore wind is the only real window where you’ll get a few rideable waves. For the rest of the 16-day window, it’s a flat, choppy waste. If you’re desperate, you might get a couple of closeouts on the 12th or 15th, but it’s not worth the drive.
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.
