The Lowdown
Alright, Rusty here again, giving you the same story in feet and miles per hour for those who think that way. This forecast is a tough one—long stretches of nothing good until we get a little pulse in early August.
The only break we’ve got to talk about is a reef setup, for advanced surfers only. It’s fairly consistent when the swell shows, but for the first week and a half, it’s a no-go. From Wednesday afternoon, July 29th, through to August 7th, winds are mostly out of the north and northwest, coming sideways or onshore, with surf ranging from about 1 foot to just over 4 feet. The energy is weak to moderate, but the quality is poor—choppy, lumpy, and messy. Nothing to get excited about.
On the morning of Thursday, August 6th, we get a brief glassy moment—wind from the northwest at just 3 mph, almost calm. The swell is around 2 feet from the west-northwest, period 10 seconds, decent for shape. Energy is weak at 85. But the report says it’s only “surfable but ordinary,” so don’t rush.
The real standout is the morning of Saturday, August 8th. Swell jumps to about 5 feet from the west-northwest, period 10 seconds, with combined energy at 505—that’s strong to very strong. Wind is light from the west-southwest at 6 mph, cross-onshore but with small ripples. It’s a marginal call, but for an advanced crowd, this is the best in the window. The swell direction is close to the optimum southwest for this reef. Water temp is around 68°F, which is about average for the time of year. Expect crowds at this spot—it’s “often” busy.
After that, it’s downhill again. Sunday the 9th drops to about 4 feet and cross-onshore winds, and the next week is a mess of stronger winds—up to 28 mph—and tiny surf, with energy as low as 5. By the 10th to the 13th, it’s all cross-shore, strong breezes, and waves under 3 feet. Not worth the drive.
So, if you’re an experienced surfer, aim for the morning of Saturday, August 8th. That’s your window. The rest? A long blank spell that’s pretty normal for this area.
Keep your chin up, and the surf will come back.
Rusty.

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