The Lowdown
Alright, Rusty here again, switching to the old numbers.
First up, it's gonna be a pretty average run at Choralillo – a consistent point break that's exposed to that SW swell. The energy's there, but the wind's not doing us any favours for the first week or so. We're looking at a solid start to the run with a big pulse of swell arriving on the morning of the 28th – a 10ft SW groundswell with a very long 15-second period. That's got strong wave energy (3377), but it's coming with a cross-onshore wind, making it fairly choppy. That's a bit of a bummer for a setup that loves clean conditions. The water temp is about average for the time of year, nothing unusual there.
The surf stays rideable but messy through the weekend and into early next week, with that SW swell dropping from 7ft down to around 4ft. The winds are mainly cross or cross-onshore, keeping things bumpy. The energy drops from moderate (1589) to more modest levels (656) by Monday the 31st. By Tuesday the 1st of September, the swell goes tiny at 2ft, but you'll notice a jump in period to 19 seconds – that's an ultra-long period groundswell, but it's got no size to push it. That'll just be a glassy wall with no push.
There's a bit of a pick-up mid-week around the 3rd and 4th, with 5ft to 5ft SW swell and period in the 14-16 second range. The wind lightens up a little, especially on the 4th afternoon with a gentle cross-shore breeze. That's probably the most decent window in the first week if you're after something clean-ish.
The second week gets interesting. The swell fills back in around Monday the 8th of September, with 6ft to 7ft SW groundswell moving in, periods up at 16-17 seconds, and combined energy climbing back up to strong levels (2341 to 2465). But again, the wind is cross-shore, keeping a chop on it.
Now, the real standout – and it's a promising one – is Wednesday the 9th of September. Wednesday morning we see a 6ft SW swell with 15-second period, and the wind is light and cross-offshore from the WNW. That combo will clean up the point nicely. Wednesday afternoon gets even better, with the wind swinging onshore from the West, but the report says "unknown" for the wave state, which is a bit of a tease. That morning session, though, looks like the pick of the whole 16-day run. There's a chance of some crowds here since it's a known spot, but for that quality with light offshores, it's worth it.
After that, the swell drops away again into the weekend, with winds turning back to cross-onshore and choppy conditions returning. The final few days from the 11th September look poor, with small swell and messy winds.
So if you're looking for a window, the stand-out is Wednesday morning the 9th of September at Choralillo. It's a little way off, so keep an eye on it, but the potential is there for a really good session. The first week is more about getting wet than scoring perfection.
Rusty.

Information about the Choralillo Surf forecast
The above surf forecast table for Choralillo provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Choralillo can be found by selecting the local surf guide option on the grey menu. Our Choralillo 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 (Choralillo) 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 Choralillo 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.
Choralillo is 29 km (18 miles) from the city of Mejillones. If you plan a holiday in Antofagasta, look for hotels and other accommodation in Mejillones. Mejillones has rooms for a wide range of budgets as well as car hire and transport links.
