The Lowdown
Alright, let's get into it.
We're looking at a solid run of swell heading our way, but you've got to pick your moments with the wind. The action kicks off on Wednesday the 12th, but conditions are a bit tricky to start.
Wednesday the 12th sees a solid SW groundswell, around 5 to 6 feet, with a very long period of 17 to 18 seconds. That's a lot of energy pushing in (combined energy around 2599 and 2392), but the wind is a problem. It's cross to onshore, so the surf will be messy and hard to read. Not the day to get excited.
Thursday the 13th is where it starts to clean up. We've got a similar size swell, 6 feet in the morning from the SW, period still a long 17 seconds. The wind swings to a light cross-offshore in the morning, turning to a clean offshore from the NNW by the afternoon. The wave energy is still very strong (2328 in the morning, 1818 in the afternoon). The descriptions say "excellent for experienced surfers," and that's because it's a good, powerful wave, but the size and the long period mean it's not a beginner wave. For the experienced crew, Thursday afternoon looks prime.
Friday the 14th drops off a touch in size to a consistent 5 feet from the SW, but the wind stays clean offshore all day from the NNW and NW. Combined energy drops to moderate levels (922 and 876), but the conditions will be clean and fun. A great option for a wider range of surfers.
Now, Saturday the 15th morning is a standout. The swell is a clean 5 feet from the WSW with a 14-second period. The magic is the wind: glassy, dead calm. The wave energy is moderate (828). For a reef break like Danger Reef, a glassy morning with a nice SW groundswell is about as good as it gets. You'll have clean, lined-up waves. Just be aware, the crowds are often here, so you won't be alone. Saturday afternoon is a write-off as the wind goes onshore.
Sunday the 16th is another good day. The swell is a bit smaller at 4 feet from the WSW, but with a long 14 to 15-second period and light offshore to cross-offshore winds all day, it'll be clean and fun.
Then we get to Monday the 17th, and this is the pick of the whole run. A new pulse of WSW swell pushes through, hitting 7 feet in the morning with a 14-second period. The combined energy jumps right up (1593), and the wind is glassy in the morning, swinging to a clean cross-offshore in the afternoon. This is a powerful, clean swell at a solid size for the experienced surfer. For the experts, Monday morning is the one to circle.
Tuesday the 18th is still clean with offshore to cross-offshore winds, but the swell drops back to 5 to 5 feet and the energy is lower (681). Still a fun, clean day.
Wednesday the 19th and Thursday the 20th are a total write-off. Strong onshore winds, even if there is a bit of swell, it'll be blown out and messy.
Friday the 21st is interesting. The swell picks back up to a consistent 6 feet from the SW with a 13-second period, and the wind is clean, cross-offshore all day. The combined energy is strong again (1224 and 1279). This could be another really good day.
Saturday the 22nd and Sunday the 23rd are another rough patch. The swell is still around 5 to 6 feet, but strong onshore and cross-onshore winds from the SSE will make a mess of it.
The run finishes with a glimmer of hope on Monday the 24th. Glassy conditions in the morning with a 4 feet SSW swell and a 12-second period. The energy is moderate (860), and it'll be a small, clean, fun morning session. The afternoon turns messy again.
The last few days from Tuesday the 25th onward are small and wind-affected, not worth getting excited about.
So, to sum it up: if you're experienced, Monday the 17th is your day. Glassy, solid 7 feet SW swell, powerful. For the best all-round conditions, Saturday the 15th morning is a treat, with a glassy 5 feet swell. And don't sleep on Friday the 21st either, as it looks clean with a solid swell.

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.
