The Lowdown
Oi, Rusty here. Let’s be straight with you – the next couple of weeks are looking pretty flat for Il Convento. This is a reef and point set-up that's exposed to the swell, but it's inconsistent, and right now, it's just not delivering. We’ve got a big gap of no real surf to start, with the first tiny bit of action not showing up until Thursday the 10th, and even then, it’s nothing to write home about.
Thursday morning, September 10th, we might see a tiny 2ft SE swell, but it's got a short period of just 5 seconds – that’s weak, windswell stuff. The wind is a cross-offshore from the north at 12 mph, keeping it clean, but the energy is pathetic, a combined energy of just 15. It’s better than nothing, but only just. The morning is the call, as the afternoon goes cross-onshore.
We get a few more of these tiny, short-period pulses through the next week – 0.3ft to 0.7ft from the SE, S, and NE – all with periods of 4-6 seconds. The combined energy never gets above 3. The offshore winds in the mornings (NW, NNW) will keep the surface clean, but there’s just no power in the water. This is strictly beginner territory if they’re desperate, but honestly, it’s more of a paddle than a surf.
The week after, around Saturday the 19th and Sunday the 20th, we see a slight bump. The swell picks up to 2ft-2ft from the SSE and SE, still with a short 5-second period. The combined energy climbs a bit, hitting 28 on Sunday morning. That Sunday morning, the 20th, is actually the best-looking window: a 2ft SE swell, glassy conditions with a calm wind from the WNW – that’s clean. But this is still small, weak surf. It’s not going to bowl.
The final morning of the forecast, Thursday the 24th, shows a 2ft SE swell with a 5-second period and a clean offshore wind from the NNW (9 mph). The combined energy here is 30. It’s the best of a boring bunch, but it’s still not a standout.
Bottom line: There are no standouts. The swell is too small, the period is too short, and the energy is weak. For a spot that’s inconsistent anyway, this is a pretty blank run. If you’re desperate for a bump, the glassy Sunday morning the 20th is your best bet for a clean, tiny wave. Otherwise, keep your gear dry. Forecasts can change, but right now, it’s a waiting game.
Rusty.

Information about the Il Convento Surf forecast
The above surf forecast table for Il Convento provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Il Convento can be found by selecting the local surf guide option on the grey menu. Our Il Convento 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 (Il Convento) 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 Il Convento 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.
Il Convento is 20 km (12 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.
