The Lowdown
Alright mate, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
First off, I gotta be straight with you – it’s a tough run. We’re looking at a long stretch of nothing much from now right through to the end of August. The water’s sitting at a warm 78°, which is much warmer than normal for this time of year, so you’ll be in for a tropical bath if you do paddle out, but the waves just aren’t cooperating.
At Crystals (beach/jetty), the first real sign of life doesn’t show up until Monday the 24th of August. The afternoon brings a light little 1 ft SE swell with a 12-second period, and a gentle offshore breeze from the WNW. It’s surfable, but it’s very ordinary – clean but tiny. The combined swell energy is a weak 54, so you’ll be doing a lot of waiting for small waves.
After that, things get a bit more interesting towards the end of the month. On Thursday the 27th, the swell starts to build, but the wind turns onshore and strong. By Friday the 28th, we’ve got a solid 5 ft SE swell with a 13-second period, and the combined energy is a strong 651. That’s a lot of power, but it’s coming in with a fresh NE cross-onshore wind, making it choppy and lumpy. That’s expert territory and not really clean for a paddle. If you’re into kite surfing, this setup might be more your thing.
The real standout, if you can wait, is Sunday the 30th of August. The morning brings a clean 4 ft E swell with an 8-second period, and a light SSW cross-offshore breeze. The water’s still warm, and the combined energy is moderate at 190. It’s not huge, but it’s the cleanest we’ll see all week, and for Crystals, that’s the best we’ve got. Given the consistency is only fairly consistent, and the spot is a beach/jetty, don’t expect perfection, but it’s a solid option for intermediates.
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.
