The Lowdown
Alright folks, Rusty here again. Looking at the next couple of weeks, and I’ll be honest, we’ve got a long stretch of nothing before things start to move. It’s a real flat spell, so don’t get too excited for a while.
From this Wednesday the 16th all the way through to the early part of next week, it’s basically flat. You’re looking at ankle-biters, with most readings bottoming out between 0.1m and 0.3m. Sure, we see a couple of pulses – like the 0.5m on the morning of Friday the 18th or the 0.6m on the 24th – but the energy behind them is weak, and it’s all happening in the single or low-double digits. The water is warm, though, really warm – 28° which is almost 4° warmer than usual for this time of year. That's a standout.
Then, after more than a week of this, things finally start to look interesting on Tuesday the 29th of September. We finally get a push of swell – 0.9m in the morning building to 1.2m by the afternoon, straight out of the SSE. The energy gets up to a moderate 87, so it’s the first time there’s any real push to it. The winds are light and offshore, cleaning things right up. Wednesday the 30th still has a glasy 0.8m, and even Thursday the 1st of October has a clean 0.6m to 0.7m.
So the highlight is clearly the Tuesday the 29th and Wednesday the 30th. It’s not going to be big, but it will be the biggest and cleanest we’ve seen in two weeks. As for breaks, Il Convento is the spot to check – it’s a reef and point, so it will handle this little SSE pulse better than most places. But she’s been inconsistent, so you’ll have to be patient.
Other than that, it’s a waiting game. The 29th is the day to be keen. See you in the water.
Rusty out.

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.
