The Lowdown
Alright, Rusty here. Let’s break down what’s coming for this exposed reef spot. It’s a dry spell for the most part, so don’t rush out.
First up, there’s nothing worth paddling for until Saturday the 15th. From the 7th through the 14th, it’s all small, weak surf with cross and cross-onshore winds. The wave energy is low, mostly in the double digits. It’s all "poor surf conditions," so save your energy.
The one window is Saturday the 15th, in the morning. The swell will be around 5ft from the northwest, with a 9-second period. The wind will be glassy – dead calm – so the surface will be clean and smooth. The combined energy is 436, which is moderate. It’s a reef break that prefers a southwest swell, but with those clean conditions, it will still offer some fun, lined-up waves. This is an advanced spot, fairly consistent, and crowds are possible. Water temp is about 69°, which is normal for the season.
After that morning, it falls apart. The rest of the 15th and the days after are small, weak, and messy. There’s a bump in size on the 21st with a 7ft northwest swell and strong energy (681), but the winds are fresh cross-shore, creating lumpy, bumpy conditions. That’s a rough one, not clean, and only for experts.
To sum it up: the only real chance is Saturday the 15th morning. The rest is a write-off.
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.
