The Lowdown
Alright, let’s get real about the next 16 days here. Honestly, it’s a pretty grim stretch for Roaches Reef. We’re looking at flat to tiny, messy, and wind-affected surf for the vast majority of the forecast.
The water’s sitting at 69°, which is way warmer than usual for this time of year, something like 8° above normal. That’s a real standout.
The first real week is a total write-off. From Sunday, August 23rd, right through to the end of the month, we’re looking at a run of mostly poor surf conditions. Swell heights are barely a whisper, mostly under 2ft, with weak wave energy (22 to 56). The wind is a constant problem – cross-shore and cross-onshore, often fresh, making for lumpy, choppy, and generally hopeless conditions. There’s a brief moment of glass on Sunday afternoon, but the swell is only 0.3ft. That’s not surfable.
The first week of September starts off just as flat. We’re talking 0.3ft and 0.7ft with the odd glassy moment, but no energy to speak of.
Then, finally, around Friday, September 4th, we see a pulse. The morning of the 4th, the swell bumps up to 8ft from the WSW, with a period of 9 seconds. The wave energy is strong (885). But the wind is a gentle cross-shore, which is okay, but it’s still a clean-up job. The real problem is the wind turns fresh and cross-onshore on the 5th and 6th, making a mess of it again. The setup looks more interesting for kite surfing than paddle surfing during that mid-stretch.
The biggest, most powerful swell of the entire 16 days hits on Monday, September 7th. We’re talking 10ft to 12ft groundswell from the WSW with a period of 10 seconds, and massive wave energy (1527 to 2039). That’s a serious, expert-only, dangerous amount of water. The period is solid, but not extremely long, so it has some shape. The wind on the morning is a strong cross-shore, making it messy, but the afternoon goes clean with a cross-off breeze. That’s the only true standout – a brief window of big, clean, powerful surf for the experienced crew.
So, to be blunt, there’s not much on offer. The forecast is about a 14-day gap of nothing, then one very brief, promising but risky window for experts on the 7th of September. Don’t get your hopes up for the rest of it.

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.
