The Lowdown

Alright, this is Rusty.

First off, looking at the whole 16-day window, it’s a pretty flat and frustrating stretch for Sandtracks. The wind is a constant problem. It’s almost always blowing across the reef from the ENE, which is exactly the wrong direction for this spot; it just keeps things lumpy and messy. There’s energy in the water, but it’s not lining up properly.

The water temperature is sitting at 80°F, which is just a hair above the norm for this time of year, so it’s a comfortable tropical bath.

We’re starting with nothing. The first few days from Sunday the 19th through the 22nd are a write-off. The wind is a fresh 19 mph cross-shore, and the swell is either tiny or a complete mess. The energy is moderate at best, but all that cross-chop makes it unrideable.

Monday the 20th and Tuesday the 21st show a little pulse of long-period groundswell from the south, with periods of 16 and 14 seconds. But the swell is tiny, only 2ft to 3ft, and the wind is still a moderate to fresh cross-shore, so it’s just a choppy, weak mess. The energy is getting up there, but it’s wasted energy.

The real tease comes on Wednesday the 22nd afternoon. The swell jumps to 5ft from the ENE, with a moderate 11-second period, and the combined energy screams up. That’s a lot of power. But the wind is still a fresh 19 mph cross-shore. I’d call this a green, lumpy, and frustrating wave. It’s powerful but ugly.

From Thursday the 23rd through to the end of the month, we see a long-period groundswell from the SSW, with periods of 20 seconds, here and there. That’s a very long period, which is great for a point break or reef, but with a constant fresh cross-wind, it’s just going to be a straight, bumpy wall. The energy is really strong, but the wind never gives us a break. It’s a kite-surfing setup, not a surfing one.

The last week of July and into August is more of the same. The wind stays stuck in the east, blowing cross. The swell fluctuates, but the best of a bad bunch is the morning of Sunday the 2nd of August. The swell is 4ft from the SSW, with a 16-second period, and the wind finally drops to a gentle 9 mph, though it’s cross-onshore, so it’s still a little choppy. The energy is huge. This is the only window that looks sort of doable, but even then, it’s marginal.

Honestly, there’s no standout session here. The wind is the killer. It’s a blank run for the area, and it’s not a huge surprise; sometimes the trades just don’t let up. The only flicker of hope is that Sunday the 2nd of August morning, but keep your expectations low.

Rusty.

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.
