The Lowdown
Alright folks, Rusty here. Let's have a look at what's cookin' at Hornitos over the next couple of weeks.
Right off the bat, we're looking at a bit of a slow start. The surf on Thursday the 23rd is pretty rough, with that cross-onshore wind messing things up. The water temp is sitting at 64°F, which feels a touch warmer than normal for this time of year, so that's a nice bonus.
Things start to turn around on Friday the 24th. By the afternoon, the wind goes glassy, and we get a clean little 3ft SW groundswell. The period is a nice long 13 seconds, which means those waves will have some real shape to them. It's not huge, but it's clean. The combined energy is moderate at 402.
Saturday the 25th morning is looking like the best of the early run. The swell pushes up to 4ft from the SW, still with that good 11-second period, and the wind is glassy. The wave energy is solid at 476. This is a proper window for a session. The afternoon is a bit of a step down as the wind shifts cross-onshore.
We hit a bit of a lull Sunday and Monday morning, with small, cross-onshore 2ft stuff. That long period (16 seconds) groundswell on Monday morning is there, but it's tiny and the wind is just wrong for it. The afternoon on Monday the 27th cleans up again with glassy conditions on a 3ft, 16-second swell, giving a moderate energy of 645. It's clean, but small.
Now, the first real standout comes on Tuesday the 28th morning. The swell bumps up to 6ft from the SW, with a 14-second period. The combined energy jumps to a strong 1244. The wind is offshore, so it's going to be clean. Get on it if you're an experienced surfer; that's pushing into intermediate territory.
The next big one is Wednesday the 29th morning. The wind is glassy, the swell is a solid 5ft from the WSW, and the period is 13 seconds. The energy is still strong at 669. The set-up is listed as "fairly exposed" to the swell and the optimum direction is SW, so it's all lining up. This is your best bet for the week.
We then drop back into a long stretch of marginal or poor conditions. From the 30th through to the 4th of August, there’s a lot of cross-onshore wind and small, weak swell. The energy drops way down. It's a bit of a dead zone for a solid week.
The second week promises a bit of hope. On the morning of Wednesday the 5th of August, the wind goes glassy again on a 5ft swell from the SW, with a 12-second period. That's a solid, clean wave.
But the real gem in the second week is Friday the 7th of August. The afternoon shows glassy conditions with a 5ft swell from the SW, a very long 16-second period, and a strong combined energy of 802. The forecast says "expect very good surf conditions". That is a long-range standout, so keep your fingers crossed, but it has all the makings of a classic session.
Overall, you've got a few clear windows. Wednesday morning the 29th is the pick of the first week, and Friday afternoon the 7th of August is the one to watch in the second week. The 6ft on the 28th is also a solid, powerful option for the more experienced crew.
Rusty out.

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.
