The Lowdown
Alright folks, Rusty here with a look at the surf ahead for the next couple of weeks. Let’s get straight into it.
Mate, to be brutally honest, it’s a tough stretch on the cards. The forecast period kicks off now and stretches right through to the 5th of September, but I’m looking at a long, quiet run with hardly a whisper of decent swell. The only real standout is a brief window on Saturday the 22nd of August, but even that’s a bit of a mixed bag. After that, we’re looking at a pretty big gap with no real recommendations until the very end of the period.
The main spot on the radar is Chia. It’s a beginner-friendly, fairly consistent beach break that’s exposed to swell from the SSW. The water temperature is sitting at 85°F right now, which is a massive 6°F warmer than usual for this time of year – that’s seriously unusual, so expect bathwater conditions.
The one highlight comes on Saturday morning, the 22nd of August. We’ve got a clean, 4ft swell from the west with a period of 8 seconds, and the combined wave energy sits at a moderate 227. The wind is a clean offshore from the NW at 9 mph, so the surf will be tidy and well-shaped. It’s a small, tidy option for a beginner or a longboarder, but don’t expect any power. The afternoon sees the wind swing cross-shore and pick up, so that morning window is the only real chance.
Beyond that, it’s grim. Sunday the 23rd drops away to almost nothing, and from there, the entire second week is a write-off – tiny swell, poor wind, and no real energy. We’re mostly looking at waves under 2ft and weak combined energy values in the single digits. There’s a tiny glimmer on the morning of Friday the 4th of September with a small 2ft, 5-second period swell from the WNW and clean cross-off winds, but the energy is barely there at 15. It’s a long wait for not much.
To sum it up: if you’re keen, get out on Saturday morning the 22nd of August at Chia for the cleanest, most fun little waves on offer. Otherwise, save your energy and wait for a better forecast.
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.
