The Lowdown
G'day, Rusty here. Look, I've got some bad news for you. We're in for a real flat spell. There's nothing on the cards for the next 16 days that's even worth wetting a board. The whole window is filled with tiny, messy waves and poor conditions.
Let's break it down. The first spot on the list is Reef, and it's a reef break that's fairly consistent and exposed to a SW swell. The water temp is about average for this time of year, nothing to write home about. But the outlook is grim. For the first two weeks of August, we're looking at swell heights maxing out at 3 ft, and most of the time it's 2 ft or less. The period is short, mostly 7-10 seconds, meaning weak, wind-affected waves. The combined energy is weak, barely cracking 100 (132) at its best, and often below 50. The wind is a constant issue – cross-shore or cross-onshore from the NNW, blowing 9-22 mph, making everything choppy and lumpy. It's all "poor surf conditions" with a score of 0 out of 10. Honestly, on those days with stronger wind and such small swell, it looks more interesting for kite surfing than paddle surfing.
There's a bit of a pulse mid-month. Around August 12th and 13th, the swell pushes up to 3 ft from the W with a 9-second period, and the energy climbs to moderate (168). But it's still getting hammered by a moderate to fresh cross-shore breeze, so it won't be clean. Still not worth the drive.
Then from August 15th onwards, it gets even worse. The swell drops to 0.3 ft, though the period gets very long (15-18 seconds) from the SW. That's a groundswell, but it's so small and the wind is still onshore or cross-shore, so it's just flat and messy.
So, that's the long and short of it. No standouts, no good windows. This is a blank run, and in this area, that's not unusual. It tends not to stay poor for long, but for now, leave the boards at home. Keep an eye on the charts, though – things can change.
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.
