The Lowdown
Alright folks, Rusty here. Let’s be straight with you.
Looking at the whole 16-day window, I gotta be honest – it’s a tough one for the Roaches Reef area. The swell is tiny, the energy is flat, and the conditions are just not cooperating. There’s a solid run of days with nothing worth paddling out for, so don’t be in a rush.
Starting off, we’ve got a pretty bleak stretch from Thursday, July 30, all the way through to around Wednesday, August 12. That’s nearly two weeks of poor surf. The combined swell energy is barely registering, mostly under 100 (around 27 being the highest early on, and it just gets weaker). The swell heights are laughable, hovering around 0.3 ft to 2 ft, with short periods around 5 seconds. It’s just not got any punch.
The only flicker of hope comes right at the end. On Wednesday afternoon, August 12, we see a little bump with a 2 ft swell from the west, but the period is still a short 5 seconds. The combined energy ticks up to 20 (still weak), but the wind goes glassy, so the surface will be clean. Then on Thursday morning, August 13, we get a 2 ft west swell, and Thursday afternoon is looking glassy again with a 1 ft WSW swell and calm conditions. The energy is still low (9-15), but it’s the best the window’s got.
The real standout? It’s not much of a standout, but if you’re desperate, Thursday morning, August 13 is your best bet. The swell is small at 2 ft from the west, combined energy is a weak 15 (low energy), but the glassy conditions will make it clean. For a reef break like Roaches Reef, you need that clean surface to make the most of anything. Don’t expect barrels, but you might get a few fun little rides.
The water temperature is about average for this time of year, nothing unusual. Crowds are a possibility at Roaches Reef, but with surf this small, I doubt many will be out.
For the rest of the second week, it’s more of the same – tiny 0.3 ft to 1 ft swells, weak energy, and mostly cross or cross-on winds. Not worth the drive.
Honestly, this is a classic case of a blank run. The forecast can change, but right now, you’re better off saving your energy for a better week.
Rusty.

Information about the Roaches Reef Surf forecast
The above surf forecast table for Roaches Reef provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Roaches Reef can be found by selecting the local surf guide option on the grey menu. Our Roaches Reef 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 (Roaches Reef) 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 Roaches Reef 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.
