The Lowdown
Alright folks, Rusty here. Let’s look at what’s coming up for Hornitos over the next couple of weeks.
Alright, the overall pattern is a bit of a slow burn. There’s no real standout surf here for the first week, but a few afternoons will offer clean, glassy conditions on small, workable waves. The real highlight looks like it’s going to be a solid pulse of swell that arrives around the 27th of July, but that’s a long way off and the wind is a question mark.
The first recommendation is for Monday the 13th. It’s a small day with a 2ft swell from the WSW, but the combined wave energy is still moderate at 540. The problem is a cross-on breeze, so it’s a bit bumpy. Not the best start.
Tuesday the 14th is where things get interesting. The morning has a cleaner 4ft swell from the WSW, but the real score is Tuesday afternoon. The swell picks up to 5ft from the SW with a 14-second period – that’s got some proper groundswell energy behind it with a combined energy of 786. And the wind? Glassy. Dead flat. That’s going to be clean, lined-up waves at Hornitos. Best point of the first week, hands down.
Wednesday the 15th is a repeat of the pattern: morning wind is clean but the swell is down to 3ft, while the afternoon turns glassy again with a 5ft SW swell. Another good session, but the period drops a touch to 13 seconds. Solid but not quite as good as Tuesday.
The rest of that week fades. Thursday and Friday mornings are small and onshore, and the afternoons are nothing special. The combined energy drops right off, down to 100 and 223 on Friday and Thursday afternoons.
Saturday the 18th has a glassy afternoon again with a 3ft WSW swell, but the period is only 10 seconds – short period mush. It’s surfable, but only just.
There’s a real gap from the 19th through to the 26th. A solid week of mediocrity. The wind is mostly cross-on or onshore, and the swell hangs around the 3ft to 5ft mark with short to moderate periods. The combined energy stays in the 300-500 range, but the conditions are just never quite right. The 22nd has a glassy morning but only 3ft of swell – not enough to get excited about.
Then, on the 27th of July – that’s a Monday, two weeks out – we’ve got a proper pulse of SW swell coming through. The Monday morning shows 5ft at 14 seconds, with a combined energy of 898. That’s a solid, powerful groundswell. The catch? The wind on Monday morning is onshore, and the afternoon turns cross-on with a stronger breeze. It’s a promise of good waves, but the wind might ruin it. If that wind shifts offshore, it’ll be the best session of the whole outlook. Keep an eye on it, but don’t book the day off work just yet.
So, my pick: Tuesday 14th July, afternoon. The glassy conditions and 5ft SW groundswell (14 sec) will give you clean, fun waves at Hornitos. It’s the only true standout in the near term. The 27th of July has the potential to be bigger, but it’s a gamble on the wind.
Stay stoked,
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.
