The Lowdown

G’day, Rusty here. Look, it’s been a rough stretch for surf around Roaches Reef, but there’s a light at the end of the tunnel. The next week and a bit is mostly a write-off, with a lot of onshore wind and messy conditions, but we’ve got a couple of sessions that’ll be worth the wait. The water is sitting at 68°, which is much warmer than usual for this time of year, so you won’t need a thick wetsuit.

The first real standout is Monday morning, 31 August. It’s still not perfect, but the wind is cross-offshore from the west at 19 mph, which is clean. The swell is a solid 7 ft from the WSW with a 9-second period, and the combined energy is moderate (560). It’s a roping wave for intermediates, but the onshore wind picks up in the afternoon, so get in early.

The real highlight comes on Saturday, 5 September. The morning session is looking clean with a light cross-offshore breeze from the NW at 6 mph. The swell is a punchy 5 ft from the WSW with an 11-second period, which is a nice long-period groundswell. That longer period means better-shaped waves and more energy, with a combined energy reading of 561. This is a reef break, so it’ll handle that period well. It’s an exposed spot, with the optimum swell direction from the SW, and this WSW swell is a close match. Expect very good surf conditions. Just be aware that crowds are possible here sometimes.

The other cracker is Thursday, 10 September. The morning is glassy and clean with a cross-offshore breeze from the NE at 9 mph. The swell is 6 ft from the WSW with a 10-second period, and the combined energy is strong (888). That’s a lot of punch. The afternoon is even better—glassy conditions with a light ESE breeze, and the swell bumps up to 7 ft from the WSW with a 7-second period. That’s expert territory at that size, so only the experienced crew should paddle out. It’s a beautiful window, but it’s a long way off, so keep an eye on it.

Outside of those windows, there’s a lot of wind and chop. The whole first week is blown out, with a run of mostly poor surfs from Wednesday 26 August through to Sunday 30 August. After Monday 31 August, the wind turns nasty again. Tuesday 1 September and Wednesday 2 September are ordinary, with a brief glassy window on the 2nd but the swell is only 3 ft to 3 ft. After that, it’s back to onshore winds until the 5th. There’s a gap of several days of poor conditions before the 5th, and then another gap of poor conditions until the 10th. So, get your sessions in on those two standouts.

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.
