The Lowdown

Alright, let’s see what we’ve got cookin’ over the next two weeks. It’s a slow burner, so don’t get your hopes up early. The real action is gonna be waitin’ for you at the tail end, but you’ll need some patience.

The water’s sittin’ a touch warmer than usual for this time of year, about 51°F. Not a big deal, but it’s a little more comfortable than normal.

The first few days are total garbage. Saturday the 5th and Sunday the 6th are hammered by a strong, annoying southerly wind, cross-onshore and messy. There’s some swell, around 5ft to 7ft, but the period is short and the wind has it completely chopped up. The energy is all over the place, with a reading of 356, jumping to 1344 on Sunday morning, but it’s all for nothin’. You’d be a fool to paddle out.

Monday the 7th sees the size drop, but the wind swings to a cross-offshore from the NNW. It cleans up real nice, but the swell is tiny, only 4ft dropping to 3ft. The energy is weak (222). It’s surfable if you’re really jonesin’, but it’s not gonna get your blood pumpin’. Tuesday the 8th is even smaller, with swell down to 2ft and energy at 48. Barely a ripple.

From Wednesday the 9th through to Friday the 11th, it’s a real waiting game. We’ve got tiny, clean waves in the 2ft to 4ft range, but the energy is laughable. The wind is light or cross-off, so it’s glassy, but there’s just no power. Thursday the 10th is the best of a bad run, with a light breeze and clean conditions, but the swell is only 2ft.

Friday the 11th and Saturday the 12th bring another pulse of southerly swell, but it’s accompanied by strong onshore wind. The energy jumps to 603 on Saturday, but the period is long (11 seconds), and it’s just a messy, blown-out disaster. Not for the paddle board.

Now, here’s where it gets interesting. We’ve got a standout window. Sunday the 13th is the one you need to mark on your calendar. The wind goes light from the north, cross-offshore, and the swell is a solid 4ft from the SSE with a period of 10 seconds. The combined energy is a respectable 384. The forecast is for good surf conditions. This is your best bet for a proper session. The break is Chapadmalal, a point break that’s fairly consistent. It’s a beginner-friendly spot, which is a bonus, but keep in mind, crowds are sometimes an issue. The swell is comin’ from the SSE, which is the perfect direction for this spot. It’s gonna be clean, with some real push.

The following week is a mixed bag. Monday the 14th offers a fresh offshore wind, but the swell is tiny at 3ft. It’s clean, but not much to ride. The rest of the week is a mess of onshore winds and small, weak swell. The energy is moderate, peaking at 587 on Wednesday the 16th, but it’s onshore and messy.

Thursday the 17th is another little highlight. The swell is small (3ft) but the wind is a light cross-offshore from the NNE, making it clean. The energy is 260. It’s not a big day, but it’s a clean one.

The final weekend, the 19th and 20th, fizzles out with tiny, weak swell and onshore winds. The energy is down to 97 on the 20th. Not worth a second look.

So, to wrap it up: the first week is a total washout. Sunday the 13th is the absolute standout – clean, with a decent swell and good energy. Thursday the 17th is a solid second option for a clean, small-wave session. The rest is forgettable.

Rusty.

Information about the Chapadmalal Surf forecast

The above surf forecast table for Chapadmalal provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Chapadmalal can be found by selecting the local surf guide option on the grey menu. Our Chapadmalal 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 (Chapadmalal) 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 Chapadmalal 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.
