The Lowdown
Alright, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty quiet for Chia, but we’ll walk through it day by day.
Right now, the ocean is flat as a pancake. No swell to speak of, and the water is sitting at a very warm 83°, which is much warmer than normal for this time of year – over five degrees above average, so that’s quite unusual. The week starts with a long stretch of nothing. From Wednesday the 12th right through to Saturday morning the 16th, there’s zero surf on offer. The wind is light and often glassy or offshore, but there’s simply no wave energy to work with.
Saturday afternoon the 16th sees a tiny bump appear – a small 2ft SE swell with a period of 4 seconds, so it’s short and weak, combined energy (10). The wind is cross-onshore, so it’s choppy. Not worth paddling out for.
Sunday the 17th gives a little more life. The morning offers a 3ft SE swell, period 5 seconds, combined energy (35). The wind is light and cross-offshore, so the morning session is clean. But it’s still small and weak. The afternoon turns cross-onshore and choppy again.
Monday the 18th is similar – 2ft SE swell, morning clean with cross-offshore breeze, but still tiny. The afternoon gets choppy as the wind picks up.
Tuesday the 19th sees a drop-off – 2ft ESE swell, combined energy (11). The morning is clean with a cross-offshore NW wind, but the swell is barely there.
Wednesday the 20th brings a shift. A 3ft SSW swell arrives, period 5 seconds, combined energy (40). The morning has a clean, gentle offshore NNW wind, so the little waves should be tidy. Still, it’s small, and the period is short.
From Thursday the 21st onward, we’re back to tiny, weak surf. A 0.3ft W swell on Friday morning with a 9-second period, combined energy (4), but it’s so small it’s barely a ripple. The rest of the week into the 27th shows nothing but flat spells or tiny 0.3ft to 1ft waves with low energy, despite often clean or glassy conditions.
There is no standout session in this 16-day window. The best chance for a clean, rideable wave is the morning of Thursday the 20th – a 3ft SSW swell, offshore wind, and the water will still be warm. But it’s not a day to get excited about. For beginners, it’s safe – the swell never gets above 3ft. For anyone else, it’s a flat spell.
Basically, we’re in a long dry run. The forecasts can change, but right now, there’s nothing on the horizon.
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.
