The Lowdown
Alright folks, Rusty here. Let's look at what's cookin' for the next couple of weeks.
Honestly, the first week is a bit of a bust. We're looking at a long stretch of poor surf at Sandtracks, a reef break that's fairly consistent but it's not playing ball. From Monday, July 20th, right through to the end of the following week, it's a whole lot of messy, cross-shore wind and lumpy, choppy water. The combined swell energy is moderate, but it's all blown out. You'll be fighting a cross-chop, not surfing waves. The water temperature is sittin' at 80°F, which is pretty much normal for this time of year, so no surprises there.
The first real glimmer of hope comes on Wednesday, July 29th. The morning is still a bit marginal with a light cross-onshore breeze, but the afternoon is where it's at. The wind drops right out, going glassy. We've got a 5ft swell rolling in from the ENE with an 11-second period – that's a bit of groundswell, decent energy. It's not huge, but the conditions will be clean. This is your best window in the first half of the outlook.
The following week, around Monday, August 3rd, things start to look a bit more promising. The swell picks up to about 5ft from the east, period 9 seconds, and we get a clean cross-offshore wind in the afternoon. The clean conditions and a bit more size make it a solid option. Tuesday, August 4th, we see a drop back to smaller, longer-period swell from the SSW, but the wind is back to cross, so it's a step down again.
So, the standout is clear: Wednesday, July 29th afternoon. That glassy session at Sandtracks with a clean 5ft, 11-second swell from the ENE is the one to circle. August 3rd is a solid backup, but that Wednesday is the pick of the bunch.
Rusty, signing off.

Information about the Sandtracks Surf forecast
The above surf forecast table for Sandtracks provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Sandtracks can be found by selecting the local surf guide option on the grey menu. Our Sandtracks 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 (Sandtracks) 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 Sandtracks 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.
