The Lowdown
Alright, Rusty here. Let’s have a look at what’s coming up for Hornitos.
The next couple of days are pretty quiet. Thursday morning brings a small 3ft SW swell at 12 seconds, but it’s just not doing much – a real marginal one. The water temp is sitting at 62°, which is about average for this time of year, nothing unusual there. Thursday afternoon cleans up with glassy conditions and a 3ft SW swell, but it’s still only ordinary. Not worth getting wet for.
Friday morning is even smaller, 2ft WSW, and I’d call it poor. But Friday afternoon – now you’re talking. The wind goes glassy, the swell jumps to 4ft from the WSW with an 11-second period, and the combined energy hits 409 (moderate). That’s a solid little window. Expect good surf conditions. This is the first real standout of the period.
Saturday has a bit of size – 4ft to 4ft – but the wind is onshore or cross-on, so it’s messy. Sunday and Monday morning stay choppy and poor. But hold on to your board for Monday afternoon, 20 July: the swell builds to 7ft from the WSW, period 12 seconds, and the wind goes glassy. The combined energy is a thumping 1046 (strong). That’s very good surf for experienced surfers – too big for beginners, but for the crew that knows what they’re doing, that’s a session to remember.
After that, the week from Tuesday 21 July through to Thursday 24 July is a mix of cross-on winds and marginal conditions. The swell hangs around 4ft to 5ft, but it’s never clean. Friday 24 July morning has a 5ft SW swell at 13 seconds, with offshore wind, but it’s still only marginal. The weekend of 25-26 July drops off quickly – tiny 1ft to 2ft, though Sunday 26 July afternoon goes glassy with a 2ft SW groundswell at 14 seconds, giving good surf conditions. Worth a look if you’re keen for a slow, clean session.
The last few days of July and into the 31st are mostly small, cross-on, and marginal. Nothing that’ll get the heart racing. The best of the entire 16-day window is Monday 20 July afternoon – that’s the one to circle on the calendar.
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.
