The Lowdown
G’day, Rusty here. I’ve had a good look at what’s on offer at Il Convento (reef and point) over the next couple of weeks, and I’ve got to be straight with you—it’s a tough run. There’s a big gap of flat, or near-flat conditions stretching from now, right through most of the period. For the first 14 days, we’re looking at a whole lot of nothing useful. Tiny, weak slop or flat spells with nothing to get excited about. It’s not until Monday the 31st of August that we finally see a bit of life, but even then, it’s marginal.
Let’s start with that Monday morning, the 31st of August. We finally get a pulse of swell from the SE at 4.6 ft, with a 6-second period. The combined energy clocks in at 253, which is moderate energy, but that short period means it’ll be pretty fat and crumbly. The wind is NNW at 9 mph, blowing cross-offshore, keeping it clean. It’s listed as marginal, so don’t expect perfection. After that, Tuesday the 1st of September morning sees a bit of offshore breeze from the NNW at 12 mph, but the swell drops right back to 1.6 ft from the SE, with energy down to 15. Tuesday afternoon goes glassy, but the swell is only 1.3 ft.
The water temperature is a standout—a scorching 85.1°F, which is about 6.7°F warmer than the long-term average. That’s very unusual for the time of year. It’ll feel like a bath.
Given the size, with swell mostly under 5 ft, it’s fine for most abilities, but the lack of consistency and poor shape is the real letdown. Honestly, the whole 16-day window is a write-off. There are no true standouts. The setup at this exposed reef and point usually needs proper swell to light up, and we just aren’t getting it. When it’s this flat and weak, you’re better off leaving the board at home.
Short Range ForecastMostly dry. Warm (max 35°C on Mon afternoon, min 25°C on Tue night). Winds increasing (calm on Mon morning, fresh winds from the NW by Tue afternoon). | Days 4-6 Weather SummaryMostly dry. Warm (max 34°C on Thu afternoon, min 25°C on Fri night).

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.
