The Lowdown
Alright folks, Rusty here. Let's have a look at what's on the cards for Danger Reef over the next couple of weeks.
Right off the bat, we're looking at a pretty grim start. The first few days are a write-off. Saturday the 5th is a complete no-go – a solid 10ft SE swell, but it's blowing a gale straight onshore at 22 mph, just churning up a mess. The water is a bit colder than normal at 58°. We’ve got to wait it out.
Sunday the 6th is still a bit of a mess. Morning is cross-onshore, and while the swell drops to 7ft, it's not quality. The afternoon cleans up slightly to a 6ft SW swell, but it's still a maybe.
Now, here's where it gets interesting. Monday the 7th is the first real standout. The morning is looking *crisp*. We've got a 4ft swell from the WSW, but the real story is the wind: glassy. Absolutely dead calm. The combined wave energy is moderate (1079), but with that glassy surface, the break will be clean as a whistle. This is excellent for the experienced crew.
The rest of the first week and into the second is a bit of a mixed bag. Monday the 14th morning is another glassy one, with a 5ft SW swell and a combined energy of 957. It's a bit smaller, but the conditions will be very, very good.
The real standout, the one you want to circle on the calendar, is Tuesday the 15th. The morning has an 8ft SW swell with a moderate offshore wind from the NW, making for clean, powerful waves. The afternoon, though, is the absolute pick of the bunch: a 10ft SW swell, a period of 14 seconds, a gentle offshore wind, and the combined energy is a massive 3431. That's a lot of power. This is a top-tier call for experienced surfers only. For the second week, Saturday the 19th morning is also a cracker: 10ft from the S, glassy, and a combined energy of 3089. Another excellent session for the experts, but it's further out, so keep that in mind.
A couple of caveats: Definitely not for beginners. Most of the decent swell is over 5ft, and the standout days are well over 8ft. The longer period swells (14-16 seconds) that are hitting on the 15th and 19th will be powerful and a bit more walled up, but at a reef break like this, that's a good thing. Crowds are often a factor here, so be prepared to share the peak.
Rusty, signing off.

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.
