The Lowdown
Alright, Rusty here, switching to feet and miles.
First few days are flat as a pancake. From Tuesday morning through the end of August, we’ve got a long, quiet stretch. The waves are tiny – mostly 0.3ft to 1ft – and the wind is mostly onshore or cross-onshore. The swell energy is weak, mostly under 100. There are a couple of glassy mornings, like Friday the 21st and Monday the 24th, but the swell is just too small to do anything with.
Things finally get interesting on the morning of Monday the 31st of August. That’s the one to circle. We’ve got a solid 7ft swell from the east, with a short period of 6 seconds, and clean conditions with a light cross-offshore breeze. The combined energy is a strong 366. The spot is Crystals, a beach/jetty, fairly exposed to the swell. The swell direction is east, close to the optimum northeast for this break, so it should wrap in okay. Keep in mind it’s a beach break, so with that size and short period, it could be a bit of a close-out mess. Not for beginners, but for the experienced crew, this is the best call in the whole 16 days. Water temp is about average for this time of year.
After that, the first few days of September drop back to smaller 4ft to 3ft swells with onshore or cross-shore winds, so the window closes quick.
The only real standout is that Monday morning, 31st August, at Crystals. Everything else is just waiting for a better run.
Rusty.

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