The Lowdown
Alright, Rusty here. Let’s break down what’s in store for this stretch.
Honestly, the first half of the forecast is a dud. From Sunday the 30th right through to about Thursday the 4th of September, you’ve got messy cross-shore winds, lumpy water, and surf that’s either tiny or sloppy. Not worth a paddle. Keep the wax in the bag.
Things perk up a little by Friday afternoon the 4th. There’s a 4ft swell from the NW with a 12-second period (moderate energy at 444). The wind shifts cross-offshore and it’s clean, but it’s still only marginal. A hint of better things.
The standout window is Sunday morning the 6th of September. Head to Reef for the best session of the period. Swell comes in at 5ft from the NW, period 11 seconds, and the combined energy is 433 – solid. Wind is offshore from the ENE at 9 mph, glassy clean. Water temp is 68°, about average for the season. This is the one to circle on the calendar. Expect crowds though – when it’s good, everyone knows. It’s an advanced-only reef setup, so bring your experience.
After that, the second week goes quiet again. A few 3ft to 5ft NW pulses around the 14th of September pop up, but onshore winds ruin the party. Nothing that’ll get you out of bed early. Lock in Sunday the 6th.
Rusty.

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