The Lowdown
Alright, let’s be straight with you—this 16-day stretch starting now is a tough one. There just isn’t any decent surf on the cards. You’re looking at a real dry spell, and honestly, it’s one of those blank runs that makes you wonder if the ocean’s forgotten how to work.
Right now, Chia is showing nothing but poor surf conditions for the next week and a half. We’re talking tiny, weak pulses—under a foot to about 3ft at best—and when the swell does try to show its face, the period is short and messy. It’s not doing anyone any favors.
We’ve got a long gap of flatness from the 31st of August right through to the 5th of September, with just a few knee-high dribbles that are not worth paddling out for. Even the glassy mornings on the 1st and 4th, with clean conditions, are empty—no swell to push through.
There’s a slight bump on the 5th of September (Saturday afternoon) where the swell jumps to around 5ft from the WNW with a period of 6 seconds, and the energy ticks up to 142 (moderate). It’s the biggest thing in the whole window, but it’s still poor quality surf. The wind turns cross-onshore and choppy, so even that one’s not going to be much to write home about. It’s just not lining up.
For beginners, this whole stretch is a washout anyway—when there is any swell, it’s too weak or blown out. For the more experienced crew, there’s just nothing here. This is a save-your-energy kind of period. Tides, boards, wetsuits—they can all wait. The ocean’s taking a break, and we’ve got no choice but to take one too.
Keep an eye on the longer range—forecasts can shift, and a blank run like this doesn’t usually last forever. But for now, honestly, I’d find another hobby for a fortnight.

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.
