The Lowdown
Alright folks, Rusty here. Looks like we’re in for a quiet stretch at Chia for a good long while. I gotta be straight with you – there’s not a single decent surf window in this whole 16-day outlook. The first solid swell doesn’t even show up on the forecast, and we’re looking at over two weeks of tiny, weak energy or flat calm. The water at Chia is sitting at a very unusual 83°F – that’s much warmer than normal for this time of year, which is a bit of a talking point, but it won’t help the waves.
For the first few days, from Wednesday the 9th through to the end of the first week, the combined energy is barely a whisper. We’re talking numbers like 2 (two) and 37 (thirty-seven) – that’s practically nothing. The wind is clean on a few mornings, like Thursday the 10th with a light cross-offshore breeze, but the swell is tiny – 1ft from the ESE with a short 5-second period. It’s just not worth paddling out for. Friday the 11th and Saturday the 12th offer a few glimpses of offshore wind, but the swell is even smaller, dropping to 0.3ft. It’s the kind of surf that makes you wonder if you left your board at home.
Heading into the second week, from the 16th to the 22nd of September, it’s more of the same flatness. The 19th and 20th see a little bump of 1ft to 2ft from the SE, but it’s short period (4 seconds) and the wind is a messy cross-onshore, making it choppy. The energy numbers are still in the single digits – weak, weak, weak. There’s a day on the 22nd with a strong cross-offshore breeze (WNW at 25 mph), but the swell is still only 1.0ft. That setup would be more interesting for kite surfing than paddle surfing; the wind is strong, but the waves are just not there.
Finally, on Wednesday the 23rd of September, we see a tiny glimmer. The morning has a gentle offshore wind from the NW and a 2ft swell from the SE with a 5-second period. The combined energy finally hits 19 (nineteen) – still low, but it’s the best we’ve seen. Even then, the afternoon brings a risk of thunderstorms and a cross-offshore breeze. The whole window is a washout, plain and simple. Chia is a fairly consistent spot, so this blank run is a bit of a surprise, but it happens. Forecasts can change, so keep your eyes peeled, but for now, I’d store the board and find something else to do.
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.
