The Lowdown
G’day, Rusty here. Let’s cut to it. The surf around Chia for the next couple of weeks is mostly flat-out poor. You’ll be staring at a lot of nothing before we get any real swell, and even then, it’s a single window that’s worth your time.
The first week is a bust. Through the 18th, there’s no swell to speak of, just bump and chop with light onshores. The 19th might offer a tiny 2ft west swell with a 4-second period and clean offshores in the morning, but it’s barely a blip. It fades fast.
From the 20th through the 28th, it’s a drought. Mornings are sometimes glassy, like on the 21st and 22nd, but there’s no wave. On the 22nd morning, you get 2ft of weak SE windswell, and the 24th has 3ft from the WSW, but both are gutless. The 25th has a slightly longer 9-second period but only 1ft. It’s all tease, no substance.
The 29th shows some life—3ft from the SE in the morning, building to 4ft from the ESE by the afternoon. But it’s short-period junk with energy still low. The 30th gets real—7ft from the SE at 7 seconds, with energy jumping to 355-368. That’s moderate power, but the wind goes onshore from the ESE, and it’s going to be a choppy, messy surf. At 7ft, this is bigger than most want, and with that short period, it’s going to be tricky.
The one to watch is the morning of the 31st. We’ve got 8ft from the SE at 7 seconds, combined energy up at 575—strong stuff. The wind swings to a WNW cross-offshore, which should give it some shape. But with that size and short period, this is expert-only. It’s going to be powerful and likely closing out on the beach. If you’re not comfortable in heavy, shifty surf, sit this one out. Crowds are likely if you do go.
Water temp is normal for this time of year. It’s a long wait, but that final morning has some teeth. Don’t waste your energy before that.
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.
