The Lowdown

G’day, Rusty here. Look, I’ll be straight with you – the next two weeks are a proper mixed bag, and for the most part, you’re going to be waiting. The first ten days are a write-off for any decent surf, but there’s a glimmer of something worth getting excited about right at the tail end if you can be patient.

We’re starting off dead quiet. Crystals (beach/jetty) is the only break on the table, and from Thursday the 20th of August right through to the end of the month, it’s pretty much all poor surf conditions. The swell is tiny for days – mostly around 0.7 ft to 2 ft – with weak, short-period windswell and a lot of messy onshore or cross-shore wind. The water temp is sitting at 77°, which is a notable 4° warmer than usual for this time of year, so you’ll feel that when you’re sitting out there doing nothing. Honestly, there’s no point paddling out; the combined wave energy is barely a whisper, often under 50 (22 to 58). The only slight reprieve comes on the 23rd and 24th with some clean offshore winds from the west, but with swell heights of just 0.7 ft to 1 ft and a very long 12-second period, it’s just not enough to break properly. You’ll be bobbing around on a lake.

That flat spell stretches all the way into the first couple of days of September. On Tuesday the 1st of September, we finally see a pulse of energy. The morning session sees glassy conditions with a light 3 ft swell from the ENE, period of 5 seconds, and a combined energy of 54. It’s only rated as “surfable but very ordinary,” so don’t get your hopes up. The afternoon builds to 5 ft from the east with a 6-second period, but a cross-shore wind messes it up, and it’s still no good.

The real standout – the only one worth circling on your calendar – is Friday the 4th of September. The morning at Crystals is glassy, absolutely flat calm wind (0 mph), with a 6 ft swell out of the ENE and an 8-second period. Now, 6 ft is getting a bit tall for beginners, but for the rest of us, it’s a sweet size. The combined energy hits a solid 704, which is strong, and the conditions are glassy – that’s the magic word. It’s a beach and jetty setup, and with that period, it’s a groundswell that will shape up nicely. The only caveat is the direction is ENE and the optimum swell direction for Crystals is NE, so it’s a little off-angle, but the glassy wind trumps that. The afternoon fades a bit with a cross-offshore wind picking up, but that morning window is your best bet in the entire 16-day run. It’s not often you get such clean conditions with decent power, and I’d be on it if I were you.

So, to sum it up: ten days of nothing, a couple of ordinary days early September, and then one real beauty on Friday morning the 4th. Patience pays off.

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.
