The Lowdown
Right, folks, Rusty here. I’ve looked at the charts for the next 16 days, and I gotta be straight with you – it’s a grim stretch for the Reef. There’s not a single moment in the whole window where the surf is worth paddling out for. This is a total blank run.
Starting right now, on Monday the 27th of July, we’ve got nothing. The swell is a mere 1.0ft from the WNW, with a period of 9 seconds. The wind is glassy in the morning, but the surf is just weak and poor. The combined energy is a paltry 15 (weak energy). The water temp is sitting at 70°, which is about average for this time of year.
We roll through the rest of the week and into the first week of August, and it’s the same story. Swell heights barely tickle 2ft to 3ft, but the wind is always cross or cross-onshore, usually from the NNW or N, making it choppy and messy. The period is short, mostly 6-10 seconds, so it’s just wind chop. The energy readings stay in the double digits, only briefly hitting 120 (moderate energy) on Saturday the 1st of August, but with a 6-second period and cross-shore wind, it’s still poor.
By the second week, from Thursday the 6th of August, the swell tries to push up to 5ft from the WNW, but the wind is howling at 22-25 mph from the N and NNW. The energy jumps to 286 (strong wave energy), but it’s a complete mess with strong cross-shore winds. After Friday the 7th, the swell just drops off a cliff. From the 8th of August onward, we’re looking at a flat spell with no measurable swell, just a few tiny 0.3ft blips from the south with a long period of 12-13 seconds, but the wind is still strong and cross-shore, so it’s useless.
The Reef is rated as an advanced reef break, but with conditions like this, it’s not even a consideration. The whole 16-day window is a write-off. This is one of those times where the area just goes quiet. Forecasts can change, but right now, there’s nothing to get excited about.
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.
