The Lowdown
Alright folks, Rusty here. Let’s get into it.
Look, I’m gonna be straight with you – the first week and a half of this outlook is a tough one for the paddle crew. We’ve got energy coming in, but the wind gods are just not playing ball. The whole forecast is for our one spot, Kings Reef, which is a reef and point setup that likes a good NNE swell. The issue is the wind is stuck cross-shore or cross-onshore from the ENE, keeping the surface messy and choppy. For a spot that’s advanced and exposed, that’s a no-go. From Wednesday the 5th of August right through to the weekend of the 16th, it’s all "poor surf conditions" with zero scores. The swell ticks up slowly, but with that moderate breeze and cross-chop, it’s not worth a paddle.
The combined energy stays moderate at best, with values like 234 and 357, but it’s all wasted on the wind. By the 8th of August, the swell is hitting 5 ft, but still with that cross-chop, so it’s just a frustrating wall of bump. The water temp is about average for this time of year, so no surprises there.
Now, we do see a shift in the second week. The swell builds steadily, and by Monday the 17th of August, we’re talking 8 ft to 8 ft from the ENE with a period of 9 seconds. The combined energy jumps into strong territory, hitting 905 and then 1148 on the afternoon of the 17th. That’s solid groundswell energy. The wind stays cross, but the forecast flips to "marginal" with a score of 1 and 2, which is a big step up from the zero. On Tuesday the 18th, we get the biggest of the run: 10 ft swell with energy at 1318. That’s heavy, and at 8 ft+, it’s for experts only. The period is 9 seconds, so it’s not super long, but it’s enough to get some decent shape. The caveat? It’s still cross-shore, so it won’t be perfect, but it’s the only window that looks remotely interesting.
The standout here is Tuesday the 18th of August. The morning shows 8 ft and the afternoon hits 10 ft, both from the ENE. The energy is through the roof, and while the wind isn’t ideal, it’s the best we’ve got. Keep an eye on it, but don’t expect glassy perfection. Crowds are likely at Kings Reef, so be prepared for company.
Honestly, if you’re a kite surfer, this whole period is more interesting with that side-off wind and building swell. For paddle surfing, it’s a long wait for a marginal shot.

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