The Lowdown
Alright, Rusty here, and I've had a good look at the Chia forecast. Let's be honest right off the bat, it's a grim stretch of days for anyone hoping to get a wave. The water is a balmy 83.8°F, which is over 6.5°F warmer than usual for this time of year, so if you're just going for a swim, it's fine. But for surfing? This is a tough read.
The whole 16-day window is basically a write-off. We're looking at a run of flat, small, or gutless conditions that stretches from the 31st of August all the way through to the 15th of September. There are no gaps in the bad news; it's just one long, quiet period.
The first few days are just painful. The afternoon of the 31st of August offers a tiny 0.3ft swell with a period of just 5 seconds, paired with a light cross-onshore breeze from the SSW at 6 mph. That's barely a ripple, and the combined swell energy is a paltry 1. Don't even bother. The rest of that first week and the next are a mix of flat spells with occasional 0.3ft or 0.7ft slop from the west or west-northwest, all with periods under 6 seconds. The wind is often light, sometimes glassy in the mornings like on the 4th and 5th of September, but there's no swell to work with. The combined energy rarely cracks single digits.
There is a slight flicker of hope around the 12th of September. Saturday morning shows a 0.7ft swell from the WNW with a period of 9 seconds and a combined energy of 7. That's a longer period for sure, but the size is still microscopic. The wind would be light and cross-offshore from the NW, which sounds nice, but you'd be struggling to get your fin wet on those waves. Then on the morning of the 13th of September (Sunday), there's a 1.3ft swell from the west with a period of 4 seconds and a combined energy of 15. Again, the numbers say it's bigger, but a 4-second period is just wind chop with no power.
Everything here is marked as "poor surf conditions" with a score of zero. Even though Chia is rated for beginners and is fairly consistent, there's nothing consistent about this forecast. The southwest wind in the afternoons is a persistent cross-onshore, which doesn't help. When there's no swell and the water is flat but glassy, it's a beautiful place to sit on a board, but you won't be paddling for anything. This is one of those stretches where the ocean just hits the snooze button. For a spot described as fairly consistent, this is a frustratingly dry period.

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.
