The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cooking at Hornitos over the next couple of weeks.

Right off the bat, we’re not looking at any proper standouts until the first week of August. The next few days are real average, with onshore winds and weak, short-period stuff. The water is sitting at 66°F, which is a full 5° warmer than usual for this time of year – that’s notably warm, about as good as it gets for a summer wetsuit or just a springy.

Thursday the 30th is a write-off with cross-on winds and marginal surf. Friday the 31st is even worse, poor conditions all day. Saturday and Sunday (1st and 2nd of August) are only slightly better, with light cross-onshore breezes and small 3ft to 4ft SW swell, but the energy is moderate (around 330 to 405) and the quality is just not there. It’s surfable but nothing to get excited about.

Then Monday the 3rd of August is where it finally turns on. Morning glassy conditions and a clean 2ft SW swell at 13 seconds – that’s a nice long-period groundswell. The energy is moderate (312) but the glassy wind makes it look clean. The afternoon is even better: glassy again, 4ft SW swell at 13 seconds, and the energy jumps to 476. That’s the best session of the first week. The swell direction is straight out of the SW, which is right in the sweet spot for this spot. Hornitos is consistent, so it’ll hold that clean shape. Crowds are possible here, so get there early.

Tuesday the 4th has a little more size in the morning (5ft, 11 seconds) but with a cross-on breeze. The afternoon, though, is glassy again with a clean 5ft SW swell at 11 seconds and energy of 559 – that’s moderate to strong. That’s another solid window.

Wednesday the 5th is onshore again, so not great. But Thursday the 6th of August brings a big pulse: 6ft SW swell at 16 seconds – that’s a very long-period groundswell. The energy spikes to 1669, which is strong. The morning is onshore, but the afternoon is light cross-on. This one is for experienced surfers only; that size and period will be powerful and a bit tricky at a beach break, but it’s a standout for the experts.

Friday the 7th holds at 5ft SW with 13-second period and moderate energy (over 700), but it’s cross-on or onshore again. The following days from Saturday the 8th onward drop back to smaller, weaker, and more ordinary conditions. The last little flash is on Friday the 14th of August: a tiny 2ft WSW swell, but with a 16-second period and glassy conditions. That’s a weird one – very small but very clean. Good for a longboard.

So, the real standout here is Monday the 3rd of August – glassy, clean, perfect size for intermediates. The second good window is the afternoon of Tuesday the 4th. After that, the big swell on Thursday the 6th is for the experienced crew only.

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.
