The Lowdown

Alright folks, Rusty here. Let's have a look at what's coming down the pipe. This forecast is for Danger Reef only, so we're focusing right there.

We've got a slow start to the period. The first few days are pretty much a write-off with strong onshore winds and messy, blown-out surf. You won't want to bother paddling out until later in the week. There's a real gap here from now through Monday the 11th, so save your energy.

Things start to look a little more promising from Wednesday the 12th. We've got a long-period groundswell arriving from the SW at 5.6ft with a period of 18 seconds. That's a very long period, and the combined swell energy is strong at 2163. On Wednesday afternoon, the wind goes glassy, which is a major positive. That'll be clean for the experienced crew, but that long period at a reef break like Danger Reef should mean some proper, lined-up waves.

The standout of the whole run, though, is shaping up to be Monday the 17th of August. That morning, we're looking at a solid 8.2ft swell from the WSW with a 16-second period, and the combined swell energy is massive at 3601. The wind is forecast to be glassy. This is an excellent setup for experienced surfers. It's a big swell, over 8ft, so this is experts-only territory, but if you can handle it, the conditions should be absolutely firing with clean, powerful surf.

There's another promising window later on. The morning of Saturday the 22nd of August sees a 7.5ft SW groundswell with a 16-second period and strong energy at 2741, with moderate offshore winds from the NNW. That's another one for the experienced crew to circle on the calendar, though it's a week and a half out so keep an eye on it.

Outside of those two big standouts, there are a few other days with cleaner winds and smaller swell, like the 15th and 16th, which would be fun on a smaller board. But for the real juice, it's all about the 12th afternoon and the big Monday the 17th.

Stay safe out there.

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.
