The Lowdown
Righto 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 been a shocker of a start. The first ten days or so are lookin' flat as a tack, with poor surf conditions and no rideable waves for a solid stretch. There's a real gap of nothing worthwhile until we get to Thursday the 25th of September. It's a bit of a drought, but keep the faith.
For the first real whisper of a wave, we head to Chia on the morning of Thursday the 25th. It's a beginner-friendly spot that's fairly consistent, but it's a bit of a blip on the radar. Swell is a tiny 4ft from the SE with a short period of just 7 seconds, pushing a moderate total wave energy (122). The water is a *very* unusual 83°, a massive 7° warmer than normal for this time of year. The morning is looking glassy with a light NE breeze making it clean, but the surf is described as "surfable but very ordinary." It's not a standout, just the first sign of life.
Honestly, looking through the rest of the period, while there are days with a bit more energy kicking around, like the afternoon of the 30th of September with a 4ft SE swell and a moderate energy reading (101), the winds are howlin' from the WNW at 19 mph, which will be a cross-offshore wind. It will be clean, but the whole setup feels more like it's better suited for a kite session than a proper paddle surf. The fetch is too short and the wind too strong for quality.
So, for a true standout, there’s really only one window that grabs my attention. Chia on the morning of Wednesday the 23rd of September. The swell hits 4ft from the ENE with a period of 5 seconds. The combined wave energy is moderate (67). The wind is glassy and clean from the ENE at just 3 mph. It's small but clean. For a beginner break that was completely flat for over a week, this is the best we've got. Just don't expect anything world-class. The crowds are possible here sometimes. After that, the swell tries to build again, but the wind and conditions just aren't cooperating for a nice rideable wave.
Keep an eye on the forecasts, things can change. Rusty out.

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.
