The Lowdown
Alright, I’m looking at the charts over the next couple of weeks, and it’s a real waiting game, folks. The surf is gonna be very small and inconsistent, with only a few brief windows of decent, clean conditions. The first real sniff of anything worthwhile won’t be for a week.
The standout, and really the only true highlight in the whole 16-day window, is Friday morning, September 11th, at Roaches Reef. This is when the stars align, but briefly. We’ve got a 4ft swell rolling in from the WSW, with a solid 9-second period. The combined swell energy is a moderate 243, which is alright for this spot. But the real kicker is the wind: a light, offshore breeze from the NNW at 6 mph. That’s gonna leave the reef glassy and clean. The water is running about 38°F warmer than normal for this time of year, sitting at 67°F, which is very unusual and a nice bonus. This is the best on offer, no question. Crowds are sometimes a problem here, but with such a long run of flatness, it might be quieter than usual.
The lead-up is grim. Monday afternoon, September 7th, is a write-off with 6ft of messy, cross-shore swell and strong wind. That setup is more interesting for kite surfing than paddle surfing. Tuesday the 8th has a drop in size, and while the wind is cleaner, the swell is weak and dropping fast. Wednesday and Thursday are tiny, with barely any energy.
After Friday’s brief window, the weekend of the 12th and 13th is back to small, weak, and choppy conditions. The following week, from the 14th through the 19th, is a desert. The swell fades to nothing, often below 2ft, with combined energy values in the low double digits. There’s a glimmer of hope on Sunday morning, September 20th, with a 3ft, 8-second swell from the west and a light cross-offshore breeze. The energy is back up to 132, but the conditions are described as very ordinary. It’s surfable, but nothing to get excited about.
After that, a strong southwesterly wind on the 21st ruins it again, and the outlook ends with tiny, wind-affected dribble.
So, to sum it up: if you’re free on Friday morning the 11th, get to Roaches Reef. It’s the only proper session in the forecast. The rest is a long stretch of flat and poor conditions. It’s a tough run, but it won’t be like this forever.

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.
