The Lowdown
G’day, Rusty here. Alright, I’ll be honest – it’s been a tough go. Checking out the next 16 days, there’s a real long dry spell before we finally get a little pulse worth paddling for. The first surf we see isn’t until Monday the 24th of August, so that’s a solid 12 days of nothing much. Between now and then, it’s either flat or blown-out junk, even if some mornings are glassy – no swell to work with.
That first real chance comes at Chia on the morning of Monday the 24th. The wind will be a clean offshore from the NNW, which makes for clean conditions. Swell height is around 4ft from the SE with a period of 7 seconds – not a long period, but it’s real surf. The combined wave energy sits at a moderate 149, so not huge, but after a flat spell like this, it’s a welcome sight. Water temp is a very unusual 82°, which is about 4° warmer than normal for this time of year – feels like a hot tub.
The real standout hits on Tuesday the 25th of August. Chia on Tuesday morning is the one to aim for. Light offshore wind from the NW, clear skies, and a nice 4ft swell from the W with a 9-second period. That’s a longer-period groundswell, meaning more energy, better shape, and longer gaps between sets – makes paddling easier. The combined energy jumps to 375, which is moderate to strong. This is perfect for intermediate surfers, not too big, just clean and fun. Tuesday afternoon keeps it going with 4ft, but the wind turns cross-offshore, so still ridable.
Wednesday the 26th of August morning offers the last little window, with Chia seeing a 4ft swell from the WSW and a 9-second period, with clean light winds from the NE. The energy is strong at 272. It all goes onshore again that afternoon though.
So, to sum it up: you’ve got nearly two weeks of flatness, then a short run of clean, fun-sized swell from the 24th to the 26th. The clear winner is Tuesday morning the 25th – don’t sleep on it. The swell is under 5ft, so it’s fine for most, and crowds are possible here sometimes, so expect a few heads out. After that, it looks quiet again.
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.
