The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s cookin’ at Hornitos over the next couple of weeks.
It’s a pretty quiet start for us. The first real chance to get wet doesn’t show up until Tuesday morning, July 28th, and even then it’s a bit of a mixed bag. We’ve got a long-period SW groundswell running at 5ft with a 15-second period – that’s some serious energy in the water (910). The wind is light and offshore, which is a gift, but the conditions are being described as marginal. The swell is coming from a solid direction for this spot, so it’s worth a look, but don’t expect perfection. The water temp is about average for this time of year, nothing crazy.
The pattern stays pretty messy through the rest of the week. Wednesday and Thursday offer some small, short-period swell, but the wind is mostly cross-onshore, making things choppy and uninviting. The standout moment in this first week, however, is Thursday afternoon, July 30th. The swell drops to 3ft from the WSW, but the wind goes glassy. That’s the magic word. The energy is moderate (362), but with clean, smooth conditions, those small waves will be rideable and fun for a longboard or a fish. That’s your pick for the first week.
Friday the 31st and Saturday the 1st of August are pretty poor, with weak energy and messy wind. Sunday the 2nd sees a drop-off in swell size and a short, 8-second period, which is just junky. The first week fizzles out with a whimper.
We’ve got a gap of a few days with nothing really worth paddling out for. Then, heading into the second week, things get interesting again. The best bet of the whole 16-day window looks to be Friday morning, August 7th. A solid SW groundswell pushes in at 7ft with a 13-second period, and the combined energy is pumping hard (1284). The wind is light and cross-onshore, which is workable. This is a proper, powerful swell.
Now, 7ft is getting into the zone where it’s not for beginners, but for the experienced crew, there’s some serious juice to play with. The swell direction is still ideal for Hornitos. Saturday morning, August 8th, is even bigger at 7ft (1475), but the wind is a bit stronger and more cross-onshore, so it will be a bit more of a battle. Sunday the 9th is still solid but gets blown out by a moderate breeze in the afternoon.
So, to wrap it up: the first week is a grind with one glassy window on Thursday afternoon, July 30th. The second week brings the real swell, and Friday morning, August 7th, is the standout – a punchy, powerful SW groundswell with manageable wind. It’s a bit of a wait, but it’s worth it.
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.
