The Lowdown
Alright, Rusty here. Let's break it down.
It's a tough stretch, no two ways about it. We're looking at a long, quiet run that starts now and stretches for nearly a week and a half. The first ten days or so are basically a total write-off. There's just no swell to speak of. The wind might be clean at times, but with no waves, it's a lake.
The one and only real chance, the only thing worth marking on the calendar, shows up on the morning of Wednesday, July 29th. That's the standout. Crystals is a beach/jetty setup, fairly exposed to the swell, and it's a spot that's fairly consistent. On that Wednesday morning, we've got a light, clean offshore wind from the WSW, which is perfect. The swell is a tiny 2ft from the SE with a period of 8 seconds, but the combined energy of all the swells is a weak 88 – so it's not packing any punch, but it's clean. The water's sitting at 77°, which is much warmer than normal for this time of year. It's a small wave, perfect for a log or a funboard, and with that offshore breeze, it'll be glassy. It's not a classic, but it's the only option.
After that morning, it fades out again. The afternoon of the 29th and the 30th have some surfable conditions, but the quality is too low to get fired up about. The wind picks up, and the waves are just weak. The rest of the forecast into the first of August is more of the same – small, weak, and not worth the drive.
For this stretch, if you're itching for a paddle, the morning of the 29th is your only window. Otherwise, leave the board in the shed. Forecasts can change, but for now, it's a waiting game.
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.
