The Lowdown
Alright, let’s get real about the next couple of weeks. Honestly, we're looking at a pretty flat, quiet stretch ahead, so if you’re itching for waves, you’re gonna be waiting a while. For most of this run, we're just looking at tiny, weak slop, and even that's a stretch. The water temps are way up – like, 84°F – which is a wild 7°F warmer than usual for this time of year. That’s some seriously unusual stuff, so if you’re paddling out at Chia, be ready for that.
The first real chance of anything surfable is on Monday the 21st. At Chia, we finally see some swell push through. Thursday the 18th gives us a hint with a small bump of 2ft with a weak energy of 38, but it's not worth getting excited about. Come the 21st, it's a bit more significant. The morning brings a clean 4ft of SE swell at 6 seconds, with a combined energy of 144. It’s not great – the period is short, and the swell direction isn't aligned with what the spot likes, so it'll be pretty ordinary. But, it's the first thing we've had in a while.
The standout window, if you can call it that, is Tuesday the 22nd. This is the best on offer over the whole two weeks. The morning starts to build with a 6ft W swell, a 6-second period, and energy jumping up to 310. Wind is a clean offshore NNW at 15 km/h, so the conditions should be pretty clean. The afternoon gets bigger, hitting 8ft from the W with energy at 466. But, and this is a big but, it’s coming with a stronger cross-offshore wind at 25 km/h, and the period is still short and the tide might not be with us. For a beginner, this is getting too big and the conditions are marginal. This is definitely expert territory.
After that, it fades quickly. The rest of the period drops back down to nothing. We're talking flatness from the 23rd all the way through the end of the run. So here’s the deal: don’t bother making plans for the next week. The only real hope is that Tuesday the 22nd delivers something. Keep an eye on it, but don’t get your hopes up too high.

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.
