The Lowdown
Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Chia over the next couple of weeks. I gotta be straight with you – it’s gonna be a tough stretch. We’re staring down a real dry patch.
Right now and for the next several days, we’ve got next to nothing. The waves are flat, and the forecast is spitting out "poor surf conditions" day after day. You’re looking at a solid gap of about a week with no real recommendations. Don’t bother paddling out until at least the 22nd; there’s just no energy in the water.
Now, the first sign of life comes on the 22nd of September. The morning starts small with a 1ft swell from the SE, but it’s got a short period (5 seconds) and the wind is a moderate breeze from the NE. The combined wave energy is weak at 6, and it’s still rated as poor. Not the one.
Things start to change toward the end of the window. On the 24th of September, we see a real bump in size. Swell hits 4ft from the SE with a period of 8 seconds, and the combined energy climbs to 204 – that’s moderate energy. But here’s the rub: the wind is a stiff E to ESE breeze, blowing cross to cross-on, making it choppy. It’s still rated as poor conditions. That size (4ft) is fine for a beginner like Chia is set up for, but the wind is messy.
The real standout, if you can even call it that, is on the 25th of September. We’ve got a better window in the morning. Swell picks up to 5ft from the SE with the same short period (6 seconds) and the combined energy is 201. The wind swings around to a light ENE breeze, keeping conditions cross-shore and manageable. This is the biggest, most consistent bit of swell in the whole run, but at 5ft it’s starting to get a bit too much for true beginners. And because the period is short (6 seconds), it’s gonna be a bit lumpy and disorganized, even with the lighter wind.
We also have to talk about the water. For Chia, it’s a warm 83°F, which is more than five degrees above normal for this time of year. That’s very unusual – feels like a hot bath out there.
For a beginner spot like Chia, the offshore wind from the NNW is what we want, and we do see some glassy or clean conditions on a few of those flat days early on, but there’s simply no swell to ride.
Bottom line: There’s nothing good on offer here for the next 16 days. The only day that’s even worth checking is the morning of the 25th for a small, short-period, cross-shore session, but don’t get your hopes up. This is just one of those periods where the forecasts will hopefully change. Hang loose.
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.
