The Lowdown
Alright, folks, Rusty here. We’re looking at the next couple of weeks, and I’ll be honest, it’s a tough one for the lineup. The forecast starts off with a bit of swell, but the conditions are messy. We’ll see a gap of poor surf stretch from around the 1st of August all the way through to the 12th, so there’s a long flat spell coming.
The only real action is in the first few days at 15th Street (a beach and reef break). It kicks off on the morning of July 28th. The swell is coming from the SSW at 5 ft, with a very long period of 17 seconds. That’s a proper groundswell, and while those long-period waves can be a bit straight at the beach, it’s still got some serious energy behind it – the combined swell energy is 1223, which is strong. The water is a steamy 75°, which is a whopping 8° warmer than normal for this time of year – that’s very unusual. Unfortunately, the wind is a light cross-onshore from the SW, and the report says it’s “fairly choppy.” The surf quality is marginal, and the score is low. It’s not the clean, glassy day we’re after.
The afternoon of the 28th is a similar story: 4 ft of SSW swell with a 17-second period, light cross-onshore wind, and the same choppy feel. The energy is still strong at 1151, but it’s not worth paddling out for.
We get a bit of a reprieve on the morning of Thursday, July 30th. The wind switches to light onshore from the W, and the swell drops to 4 ft from the S with a 13-second period. The energy is moderate at 891. The afternoon of the 30th and the morning of Friday, July 31st see a similar pattern: 4 ft to 5 ft S swell, light onshore winds, but the quality remains marginal. The 31st afternoon has 5 ft of S swell at 13 seconds, with light onshore wind, but it just isn’t clean.
After that, from the 1st of August, the swell drops off a cliff. We’re looking at 2 ft to 3 ft for the next ten days, with poor surf conditions flagged for every session. The wind stays light, but the energy is weak (all values under 500). The 7th of August does see a long-period 19-second SSW swell, but it’s only 1 ft to 2 ft, and the cross-onshore wind will ruin it.
The very end of the window, around the 12th of August, shows a tiny uptick: 3 ft of SW swell at 17 seconds, with energy climbing to 599. The wind is onshore, but it’s still marginal. It’s a long way off, so keep an eye on it, but don’t book the day off work.
What’s the best on offer? Look, I’m not going to lie to you. There’s no standout. The best chance is the morning of July 31st, with 5 ft of S swell and light onshore wind. It’s the biggest, and the wind is light, but it’s still a gamble. If you’re desperate, you might get a few grovelly ones. Otherwise, the long flat spell after the 1st of August is a real downer. The setup looks more interesting for kite surfing than paddle surfing for most of the window.
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.
