The Lowdown
Alright folks, Rusty here. Let’s get into it.
We’ve got a 16-day window, but don’t be in a rush. The first few days are a bit of a write-off – the swell is small and the wind is just messy enough to keep things from coming together. It’s not until Wednesday the 29th that we start seeing something worth a paddle.
Hornitos is the only break on the menu, and it’s a consistent, intermediate-friendly spot. The water is sitting at 65°F, which is a solid 5°F warmer than usual for this time of year – that’s a real treat, feels like a summer bath.
The real standout action kicks off on Wednesday morning, July 29th. We’ve got a clean 4ft of SW groundswell, with a period of 13 seconds, pushing a combined energy of 657 (moderate). The kicker? The wind is glassy. In the morning. That’s gold. The waves will be clean and lined up – a proper session for the intermediate crew. Just keep an eye on the tide, as it can make or break the shape here.
After that, things get a bit patchy again. Thursday afternoon, July 30th, offers a brief reprieve with another glassy window, but the swell drops to 3ft. It’s fun, but not the highlight.
Now, if you’re looking ahead, Thursday afternoon, August 6th is the one to circle. The forecast shows a 3ft SW swell, but with a period of 16 seconds – that’s a very long groundswell. The combined energy hits 787 (moderate-strong), and the wind goes glassy again. This is a very promising session, especially for a point or reef setup. The longer period means more energy and better-shaped waves, but it can be a bit straight at a beach break – but for Hornitos, it looks like a winner. The water should still be holding that warm anomaly too.
The following Friday and Saturday (August 7th and 8th) keep the swell in the 4ft to 5ft range with solid SW energy, but the wind is mostly cross-on or onshore, so it’s not as clean as that Thursday session. The consistency is there, but you’ll be sharing it with more chop.
Overall, the best bet is Wednesday morning, July 29th for clean, glassy conditions on a moderate SW swell, and Thursday afternoon, August 6th for a longer-period, glassy groundswell that promises real quality. The rest of the window is a mix of marginal surf and onshore winds – you can still get wet, but you won’t be writing home about it.
Stay salty.
Rusty.

Information about the Hornitos Surf forecast
The above surf forecast table for Hornitos provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Hornitos can be found by selecting the local surf guide option on the grey menu. Our Hornitos 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 (Hornitos) 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 Hornitos 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.
Hornitos is 22 km (14 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.
