The Lowdown
G'day, Rusty here. Let's talk about what Danger Reef has in store for the next couple of weeks. It's a consistent reef break that's wide open to the swell, so when it's on, it's on.
We've got a bit of a lull before the first good ones. It all starts on Saturday the 15th in the afternoon with glassy conditions. The swell is 6ft out of the WSW, with a long 14-second period. The water is 57°, which is a bit colder than usual for this time of year. The combined energy is 1050 (moderate wave energy), and with those glassy conditions, it's a great call for experienced surfers.
Sunday the 16th is a double-header. The morning has a cross-off breeze with 5ft swell, but the afternoon is the one to aim for. Clean 7ft WSW swell with offshore winds from the NW and combined energy at 1670 (moderate wave energy). That's getting a bit big for the groms. Monday the 17th keeps the run going with 7ft swell and more offshore breezes, energy reaching 1708 (moderate wave energy). This is the best of the first week—clean, punchy, and all yours.
Tuesday the 18th through to Friday the 21st morning is mostly a write-off. Onshore winds and choppy conditions mess up the 7ft to 8ft swells. Not worth the paddle.
Friday afternoon the 21st brings a clean-up. Cross-off winds and a 5ft SW swell with 11-second period. Energy is 731, but it's clean. A nice, relaxed session.
The second week has a few average days before the big one. Saturday the 22nd and Sunday the 23rd have wind issues. The real standout is Friday the 28th. Afternoon sees a solid 8ft SW swell with a very long 16-second period and offshore winds from the NW. The combined energy is huge at 3315 (strong to very strong wave energy). This is the best of the whole run—big, clean, and powerful. Only for experts at that size, and that long period will make it a treat on the reef. A true standout.
Crowds are common at Danger Reef, so expect some company on the good days. With this forecast, the end of the month is the one to lock in. Rusty.

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