The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this outlook is a tough one for the Reef. We’re looking at a 16-day window that’s pretty much a write-off for any decent surf. The first real recommendation doesn’t pop up at all, meaning we’ve got a solid gap of no surf on offer from the start. The whole period is plagued by weak, mostly cross-onshore winds and tiny, gutless swell.
The first few days, from Thursday the 16th through to the end of July, are all a washout. Swell heights barely scrape 2 ft, with periods often under 8 seconds, and the wind is almost always a cross-onshore breeze. The combined energy is weak, sitting in the double digits (46) at best, and often dropping lower. It’s just poor surf conditions, day after day. The water temp is around 66°, which is pretty average for the time of year.
We do see a little bump in combined energy on the 24th of July, with a reading of 140, and a swell of 4 ft from the NW, but it’s still a cross-onshore mess with a period of 8 seconds. Then again on the 28th of July, the energy jumps to 204 with a 3 ft swell from the NW, but the wind is still cross-onshore and choppy. Even these slightly bigger moments are marked as “poor surf conditions.” The setup is a reef, but with the wind direction and short period, it’s not going to offer anything clean.
Forget about any standout sessions. There’s nothing here that’s worth paddling out for. The entire forecast is a dud, and the conditions are so consistently poor that it’s not even worth getting the board wet. This is just one of those blank runs for the area.
Stay tuned, forecasts can change, but right now, I’d give it a miss.
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.
