The Lowdown
Alright folks, Rusty here. Let's be straight with you: the outlook for Chia over the next 16 days is a tough one. We're looking at a long, dry spell with very little to get excited about. The water is sitting at a very warm 86°, which is a solid 7° warmer than usual for this time of year – that's a standout anomaly, making it feel much warmer than normal for a surf.
The first real chance to paddle out doesn't come until Friday morning, the 21st of August. There's a small bump of swell pushing in at 3 ft from the west, with a short period of 8 seconds. The combined energy is weak at 103, so it's not going to have much punch. The wind, however, is a positive note – it's a moderate offshore from the NNW at 12 mph, which will keep the surface clean. It's surfable, but the conditions are very ordinary, so keep your expectations in check.
After that, it's a long stretch of nothing. From Friday afternoon right through to the start of September, the wave comment is repeatedly "poor surf conditions." We're talking about a gap of over a week with no real surf worth mentioning. The swell drops away to tiny, choppy, and wind-affected junk. It's a bleak run.
Things start to look a little different on Thursday, the 3rd of September. The afternoon shows a sudden spike in swell energy up to 283 (moderate energy) with a 7 ft swell from the WNW. The period is a short 6 seconds, making it a bit of a windswell mess. The wind is a fresh breeze from the WNW at 19 mph, which is cross-offshore, keeping it clean on the face. The problem is that the 7 ft swell with short period on a beach break setup is going to be a wild, bumpy, and unruly mess. This setup looks more interesting for kite surfing than paddle surfing. It's definitely not for beginners and only for the most experienced crew.
The final day of the forecast, Friday the 4th of September, offers a little hope. The morning brings a gentle offshore from the NW at 9 mph, with a 2 ft west swell. The energy is still weak at 65, but the conditions are clean. It's a tiny, weak wave, but it's about the best we'll see.
If you're desperate for a surf, the Friday morning of the 21st of August is the only real window in the near term, and it's very marginal. The bigger swell on the 3rd of September is a draw for experts only, and even then, the quality looks poor. Honestly, for the next two weeks, Chia is in a drought. It's a blank run, but that's not unusual for this area. Forecasts can change, so keep an eye on it, but don't plan your life around it.
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.
