The Lowdown
Alright, Rusty here, let's have a look at the prospects for Il Convento.
Honestly, mate, it's a tough run ahead. This spot is a reef and point set-up that usually needs a decent push of swell from the SE to work, and for the next couple of weeks, that just isn't happening. We're staring down the barrel of a long, quiet period. For the majority of this forecast, you're looking at tiny, weak waves that are barely a ripple, if there's anything at all. The combined swell energy is almost non-existent, often just a 1 or a 3, which is basically flat. There's a real gap from the 22nd of September through the 24th where there’s literally no swell energy recorded at all.
That said, there is one day that stands out as a bit of a wildcard. On Friday the 25th of September, things get a little interesting. The morning shows a new 4ft swell sneaking in from the NE with a period of 8 seconds. The combined energy jumps to 145 (moderate energy), which is a massive jump from the days before. Even though the direction isn't the preferred SE, the offshore breeze is gone, and we get a gentle cross-shore wind, which leaves the surface with just a slight cross-chop. It’s still only a 0/10 score, so don't expect perfection, but it’s the only pulse of size we see.
Then by the afternoon, that same NE swell builds to a solid 7ft with a 9-second period and the energy rockets up to a very powerful 823. That’s a heap of energy for this break. However, the wind turns cross-onshore and gets a bit chunky, making it choppy and messy. At over 8ft, that's expert-only territory, and with the onshore wind, it's going to be a battle. Honestly, that afternoon session looks more interesting for a kite surfer than a bloke on a paddleboard.
Before that, the only other hint of activity is the Sunday the 20th of September, when the morning brings a tiny 3ft swell from the SE with a bit more energy (40), and the wind is clean and cross-offshore. It’s not big, but it might be the cleanest you’ll see it all fortnight.
So, to sum it up: The standout for size, and the only real pulse of swell, is Friday the 25th of September. Talk it up all you want, but the morning is small and the afternoon is a messy, powerful close-out. For the cleanest little waves, have a look at the morning of Sunday the 20th. Otherwise, save your wax.
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.
