The Lowdown
Alright, let me look at the forecast for Crystals. It's a beach and jetty setup, and honestly, it’s been pretty quiet. There’s a long gap here with nothing to get excited about for most of the 16-day run. The first solid chance doesn't really show up until later on.
We start from August 9th right through to the morning of August 22nd, and that stretch is basically a write-off. You're looking at tiny waves – mostly 0.3ft to 1.6ft – with weak energy readings often in the single digits (like 2, 4, 11). The wind is mostly cross-off or offshore, keeping things clean, but there's just no swell to work with. It’s flat, pure and simple. A few afternoons like August 18th see a bump to 3ft and 4.6ft with moderate energy (138 to 171), but the wind turns cross-on or onshore and the wave comment says it's poor, so that’s not one to chase.
Now, the standout slot in this entire window looks like the morning of Saturday, August 22nd. We've got a 3.6ft swell coming from the northeast, with a period of 6 seconds. It's not a long period, but the combined swell energy is a moderate 107. The real kicker here is the wind: it’s glassy. A slight air with no wind at all. That makes for the cleanest conditions you'll see. This is a beach/jetty break, so with a short period like that, it might be a little soft, but glassy conditions make anything surfable. The water temp is 77.4°F, which is a touch warmer than normal for this time of year, so you’ll be comfortable out there.
The crowds at Crystals can show up sometimes, so on a glassy Saturday morning in late August, expect a few others with the same idea. For the intermediate surfer, this is the one to aim for. Everything else in the 16 days is either too small or blown out. It’s a long wait, but that Saturday morning has a shot at being fun.

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.
