The Lowdown
Alright, this is Rusty, and I’ve got the lowdown on the local stretch for the next couple of weeks. Let’s get into it.
We’re looking at a pretty quiet spell ahead at Chia. The entire 16-day window is basically a flat, low-energy affair. There’s a long gap of nothing happening, so don’t bother checking the buoy until we get closer to the end of the second week. The water is running much warmer than normal for this time of year, sitting at 83°F, which is a solid 6°F above average – that’s a real standout, and it’s going to feel like a bath.
The first sign of any life doesn’t show up until Thursday the 10th of September. The morning offers a tiny 3ft swell from the SE, with a combined energy of just 39 (weak). Winds are light and cross-offshore from the NNE, which will keep things clean. The afternoon sees the swell drop to 2ft but the energy bumps up a notch to 43, with a moderate cross-off breeze from the WNW. It’s still weak, though.
Friday the 11th of September is even smaller, with a 1.0ft WNW swell in the morning and a period of 8 seconds. The combined energy is a paltry 28. It’s clean, but there’s nothing to push you around on.
The best of a bad bunch actually lands on Wednesday the 16th of September. The morning shows a 2ft swell from the W, with a combined energy of 26 (weak). The winds are light and cross-offshore from the north. It’s not going to be a classic, but it’s the most interesting wave height we’ve seen in a while.
Then, on Friday the 18th of September, we get a couple of half-decent windows. The morning is glassy with a 1ft WNW swell (period of 8 seconds) and a combined energy of 46. The afternoon sees a slight increase to 2ft from the W, with energy hitting 51. Winds are light cross-on from the SSW, which will put a bit of texture on the surface, but it’s the highest energy reading of the entire forecast.
Honestly, nothing here is a standout. The swell is tiny, the periods are short, and the energy is weak across the board. It’s strictly a beginner-friendly playground when there’s any ripple at all. If you’re desperate for a paddle, keep an eye on the 18th of September, but don’t expect much.
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.
