The Lowdown
G’day, this is Rusty.
Let’s level with you – Chia is in a flat spell. From Monday 17th August all the way through to the end of the month, there’s nothing worth paddling out for. The water is a warm 30°, which is 4° hotter than average for this time of year – that’s weirdly warm, like bath water.
The only real chance comes on the morning of Saturday the 29th of August. We’ve got a 7ft swell from the southeast, with a period of 7 seconds. The combined energy is moderate at 597 (moderate wave energy), and the wind is offshore out of the NNW at 10 km/h, so it’ll be clean. That’s a solid size, but it’s on the edge of being too big for beginners – better for experienced surfers. The swell direction is from the southeast, not the ideal SSW, but the offshore breeze and clean conditions make it the best call in the whole 16 days. The period is short, so don’t expect a ton of power, just a few fun ones.
The rest of the forecast is tiny, weak, and messy. The Saturday afternoon drops to 5ft, and from Sunday 30th onward it’s back to knee-high slop. There’s a long dry spell before that Saturday morning, so it’s a one-day window. It’s a long-range call, so fingers crossed it holds.

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.
