The Lowdown

Alright folks, Rusty here. Let’s break down what’s happening at Crystals over the next couple of weeks. Gotta be honest, it’s a dry run. For a spot that usually gets some exposure, we’re just not catching a decent swell with good wind.

The first few days look flat as a pancake. Starting Wednesday the 19th of August, we’ve got a measly 0.3ft swell from the NE with a period of only 4 seconds. The combined energy is a weak 2. The water temp is sitting at 77°, which is a touch warmer than normal for this time of year. Even with a clean offshore breeze, there’s just nothing to ride.

We’re looking at a real quiet spell. From Wednesday the 19th through to Monday the 24th, it’s mostly tiny 1ft to 2ft slop. The wind is a mixed bag – some clean moments, sure, but the swell is pathetic. Combined energy stays below 100. Thursday the 20th is clean in the morning but only 1ft. Friday the 21st turns choppy with onshore winds. The weekend of the 22nd and 23rd is poor – a 3ft easterly swell on Saturday morning with a period of only 5 seconds, so it’s just bumpy and weak. Sunday is back to 1ft.

The best window across the whole forecast comes at the end of August. Thursday the 27th afternoon sees the wind turn offshore from the west with 1ft from the SE and a 10-second period. Clean, but tiny. Friday the 28th afternoon is similar – 2ft from the SE, 9-second period, clean offshore wind, combined energy of 75. Surfable, but nothing special.

The real highlight, if you can call it that, lands on Sunday the 30th of August. That morning at Crystals is looking as good as it gets. We’ve got 2ft from the SE with a 9-second period, combined energy at 85, and the wind is glassy – dead calm. For a beach/jetty setup, that is as clean as it comes. Because it’s fairly consistent and sometimes crowded, you might have some company, but for a small-wave cruiser session, that’s your day.

Heading into the first week of September, the pattern stays low-key. The energy picks up a little – Monday the 31st of August morning has 2ft and combined energy of 122 with clean wind – but the swell height never pushes past 2ft. That’s beginner-friendly territory. On Tuesday the 1st of September, there’s a 2ft SE swell with a very long 13-second period. That’s proper groundswell, which can make for longer lines but might run a bit straight on a beach break. Still, the morning is clean with a cross-offshore breeze.

Overall, it’s a flat and slow outlook. Don’t expect any barrels, but that glassy Sunday morning on the 30th is your best bet for a clean, small-wave paddle.

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.
