The Lowdown
Imperial Version
Alright folks, Rusty here. Let’s cut through the chatter and see what Danger Reef is serving up. We’ve got a 16-day window, and it’s a bit of a mixed bag, but there are some proper moments to lock in.
The water is sitting at 57°, which is a bit colder than normal for this time of year—nothing brutal, but you’ll want a hood if you’re sensitive.
We kick off on Wednesday the 2nd. It’s nothing to write home about to start. A 8ft SW swell at 13 seconds, but the wind is cross-on from the south. The wave energy is pumping at 2412, but it’s a bit messy. The tide might be playing tricks too. It’s a marginal call.
Thursday the 3rd is a write-off. The wind cranks up from the SE, hitting 31 mph on the afternoon, shoving 13ft of lumpy, short-period SSE swell onshore. That’s kite-surfing territory, not paddle surfing. Friday and Saturday are the same story—howling onshore winds and big, messy surf. Just stay home.
Now, Sunday the 6th is where my heart starts beating a little faster. The morning is still a bit of a question mark with a 7ft SW swell and a very long 18-second period, giving us massive energy (3728). But the wind is light. The real magic is Sunday afternoon. The wind drops to glassy, and we’ve got a 6ft SW groundswell at 16 seconds. That’s 2064 in energy. That’s the standout of the first week. Danger Reef is a reef break, so that long-period swell will be a dream. The swell is 6ft, so it’s manageable for intermediates, but the power is real. It’s a glassy, clean session. Crowds are often here, so you might have some company, but for that quality, it’s worth it.
Monday the 7th is a bit of a letdown after that. The swell drops to 5ft, and the wind is a moderate cross-off from the NNW. It’s clean but not the same.
Tuesday the 8th dawns glassy again with a 3ft SSW swell. The energy is down to 343. It’s small, clean, and good for a longboard or a funboard.
The middle of the week from the 9th to the 11th is a mix of light cross-on winds and small swell. Thursday the 10th morning is worth a look—glassy again with a 5ft SW swell (711 energy). It’s clean but not the big one.
Then we hit a rough patch from the 12th to the 14th. Huge onshore winds, big messy swell. The 13th sees 10ft SSW swell with 4598 energy, but it’s all blown out. Keep the board in the car.
The second week starts to look up on Tuesday the 15th afternoon. The wind swings offshore from the NW, and we get a clean 4ft SSE swell. It’s a gentle offshore, so the waves will be smooth. Not a monster, but a fun session.
Then Wednesday the 16th and Thursday the 17th are the real long-range standouts. The wind is offshore or cross-off from the NNW and W, and we’ve got a powerful 8ft to 10ft SW groundswell rolling in with periods of 14 to 17 seconds. The energy is huge—over 3500. This is big, clean, powerful surf. At 8ft to 10ft, this is only for experts. The swell is long-period, so it will be bowling at this reef. This is a serious swell, but it’s a week and a half out, so keep your fingers crossed.
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.
