The Lowdown
Alright folks, Rusty here. Let’s be straight with you. The next couple of weeks are looking pretty flat and quiet. We’ve got a run of days with barely a ripple, so if you’re hanging for a wave, you’re gonna have to be patient. The ocean is just taking a breather, but that doesn’t mean it’s over. There are a few little pulses on the horizon that might just get the heart going, but we’re not talking about any hero waves.
First up, there’s nothing surfable for the first couple of days. Saturday and Sunday are total write-offs with tiny, weak energy and flat conditions. The water is a warm 83.3°F, which is a solid 7.2°F warmer than normal for this time of year—that’s a big deal, and it's really noticeable when you get in. It’s like bathwater out there.
We start to see the very first hint of life on Monday morning, the 16th, but it's still tiny. The swell is only 1ft from the SE with a short 7-second period, and the energy is barely a whisper. It’s clean though, with a light NNW wind, but you’d be stretching to call it a surf.
The best of this flat spell arrives on Thursday the 18th and Friday the 19th. Thursday morning sees the swell bump up to 2ft from the ESE with an 8-second period, and the energy climbs to a moderate 52. That’s the most push we see all week, with light offshore winds keeping things clean. It’s small, but it’s the most promising window. Friday stays around 1ft but with a bit of period on it.
Then we drop back into another flat spell. From the 20th through to the end of the month, it’s mostly tiny or zero. There’s a small knee-high pulse on the 22nd, but it’s messing around with onshore winds. The 27th has a bit of clean offshore wind but no swell at all to speak of. This long, flat stretch is pretty much par for the course here, but forecasts change, so keep an eye out.
For a beginner, the water is warm and the conditions are clean, but there just isn’t any push. If you’re just starting out, this is a perfect time to practice your paddling and turtle rolls. For everyone else, it’s a waiting game.
Alright, keep the faith, check back in a few days, and I’ll see what’s brewing on the charts.

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.
