The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s on offer for the next couple of weeks.
Right off the bat, I gotta be straight with you – it’s pretty bleak. We’re looking at a long stretch of flat or near-flat conditions. From today, Wednesday the 5th of August, all the way through to the morning of Tuesday the 18th of August, there’s nothing worth getting wet for. We’re talking about a solid gap of nearly two weeks where the swell is just too small or non-existent, with energy readings barely ticking over (6). The wind does go glassy or light offshore a few times, but with wave heights stuck at 0.7 ft or 1.0 ft, it’s a lake, not a surf break.
The first real flicker of life shows up on the morning of Tuesday the 18th of August down at Chia. The swell lifts to a tiny 2 ft from the SE, with a period of only 5 seconds. That’s a short-period, weak windswell, and the combined energy climbs to a still-modest 20. The wind is a clean cross-offshore from the NW at 6 mph, so the surface will be clean. But honestly, 2 ft is barely rideable, even for a beginner. It’s not a standout, it’s just the first sign that the ocean isn’t broken.
A slightly better pulse arrives on the morning of Thursday the 20th of August. Again it’s Chia, with a 2 ft swell, but this time it’s from the W with a period of 8 seconds. The combined energy hits 55, which is still weak but at least has a bit more push. The real good news is the wind: glassy, calm, with a WNW breeze at 3 mph. That’s as clean as it gets. The water temp is about average for this time of year, so no surprises there.
Even so, with the swell barely cracking 2 ft and the period just on 8 seconds, these waves are going to be small and weak. It’s a beginner-friendly wave, but only just. Don’t expect any power. The crowds at Chia are listed as “sometimes,” so you might get a few others out there, but honestly, with surf this small, most folks won’t bother.
So, the best of a very poor bunch is undoubtedly the morning of Thursday the 20th of August. A glassy surface, a tiny waist-high lump from the west, and a bit of energy behind it. It’s not a day to call in sick for, but if you’re desperate, you’ll find a clean, soft wave to cruise on.
That’s the long and short of it. A two-week flat spell, then a couple of small, clean mornings. Forecasts can change, so keep an eye on it, but right now, the board stays in the shed.
Rusty.

Information about the Chia Surf forecast
The above surf forecast table for Chia provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Chia can be found by selecting the local surf guide option on the grey menu. Our Chia 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 (Chia) 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 Chia 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.
Chia is 32 km (20 miles) from the city of Capoterra. If you plan a holiday in Sardinia, look for hotels and other accommodation in Capoterra. Capoterra has rooms for a wide range of budgets as well as car hire and transport links.
