The Lowdown
Alright, let’s talk about what’s happening at Crystals. Only one break in the mix, a beach and jetty spot that’s fairly exposed. And for most of the next two weeks, it’s looking pretty poor.
The first few days are a bust. Thursday the 13th and Friday the 14th are showing tiny surf, about 0.7ft to 1ft from the ESE or SE, with short periods of 8 to 9 seconds. Water temp is normal for this time of year. The combined swell energy is in the low teens to twenties – that's weak stuff. Winds are light offshore on Thursday morning, keeping it clean, but there's nothing to ride. Saturday the 15th gets a slight bump to about 3ft from the NE, but the period drops to just 4 seconds, and the wind is cross-on from the NE at about 12 mph. Choppy and messy.
Sunday the 16th is even worse, with dropping surf and fresh cross-shore winds up to 19 mph. Monday the 17th is completely flat and glassy – great for a kayak, not for surfing. Tuesday the 18th brings a long-period 14-second groundswell from the SE, but only 1ft. The energy is still weak at 43, and it’s cross-on. Too small.
The rest of that week and the next is a repeating pattern: tiny waves from 1ft to 2ft from the SE or S, periods between 8 and 11 seconds. Combined energy stays below 100 – often in the 20s to 70s. Winds are sometimes cross or cross-off, so it can look clean, but the swell just isn’t there. One morning, the 22nd, shows about 3ft from the S with a short 5-second period and glassy conditions – surfable but very ordinary. Energy at 72.
Then, towards Thursday the 27th and Friday the 28th, there’s a change. Swell builds to 5ft to 7ft from the ENE with periods around 6 to 7 seconds. Combined energy hits 233 and then 364 – that’s moderate energy. Winds look good: clean cross-off on the afternoon of the 27th from the SW at 12 mph, and on the morning of the 28th from the NW at 12 mph. The short period means it’ll be a bit lumpy, but for this break, that’s the best stretch of the whole 16 days. At over 5ft, it’s not for beginners. Crowds are “sometimes” at Crystals, so you might see a few others.
Bottom line: there’s a long, quiet gap of nearly two weeks before that last week of August offers something to get excited about. Hold out for the 27th and 28th – it’s not perfect, but it’s the pick of the lot.

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.
