The Lowdown
Alright, Rusty here, let's talk about what we've got on the cards.
Right off the bat, this is a flat spell. A long one. We’re looking at a stretch of almost nothing for over a week. The water is sitting at a balmy 82.6°, which is a good 6.7° warmer than usual for this time of year—that’s very unusual, a real tropical bath. But for waves? Zilch.
We’re looking at a solid nine days of clean skies and light breezes through to the 23rd of September, but the swell is basically non-existent. You’ll be staring at a glassy ocean with maybe a tiny 0.3ft ripple if you're lucky, but that’s not surf. It’s a flat calm. There's not a single recommendation in the first week and a half. Expect a lot of downtime.
Then, on the morning of Saturday the 26th of September, there's a little flicker of life. A 2ft swell shows up from the SE, but the wind swings onshore in the arvo and it’s messy. The combined energy is still only a weak 10, so it's barely a blip.
The first real chance of something rideable arrives on the morning of Sunday the 27th. We’ll see a 4ft SSE swell with a modest 6-second period. The wind is cross-off from the NNW, keeping the lineup clean. The energy hits a moderate 93, but the surf quality is still described as poor. It’s small and a bit fat.
Now, the standout window is Monday the 28th. The morning at Il Convento is the pick of the whole outlook. A 3.6ft SE swell lifts the combined energy to a solid moderate 160, and we get offshore winds from the NNW, keeping it clean. It’s very ordinary, surfable, but it’s the best we’ve got. The swell direction matches the optimum SE, and with the reef and point set-up, it should handle that period okay. It’s inconsistent here though, so don’t expect a conveyor belt. Crowds are a possibility, but in a flat spell like this, the few who turn up will be keen.
After that, Tuesday the 29th of September morning offers another small window with a 4ft SE swell and glassy conditions from a light WNW breeze, giving us a moderate 109 energy reading. Surfable, but again, very ordinary.
That’s your lot. A long, painful flat spell, then a couple of mornings that might just save the week for the patient ones.

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.
