The Lowdown
G'day, it's Rusty. Look, I won't lie to you, the next couple of weeks at Hornitos are a bit of a mixed bag, but there's a little window of something to get excited about if you're patient. The water is a toasty 65°, which is much warmer than normal for this time of year, so you can leave the wetsuit at home.
The week starts slow. Wednesday the 26th through to the end of the month is pretty flat with weak, messy energy. You're looking at tiny 2ft to 2ft swell from the SW and WSW, with a light cross-on breeze mucking things up. The combined energy is weak, sitting between 133 and 190, and the surf is just poor. Not worth a paddle.
Then we get a pulse starting Friday the 28th. The swell jumps to 7ft from the SW with a period of 15 seconds, and the combined energy hits a strong 1810. That's a proper groundswell. The wind is light and onshore in the morning, which is a bit of a shame, but it's still a solid wall of water. This swell is over 5ft, so it's getting a bit much for beginners, and at 7ft, it's pushing into expert territory. The long period means it'll be better at a point or reef than a straight beach break, as it might close out. The afternoon gets a bit choppy with a 9 mph cross-on breeze, but Friday morning is the best of it.
Saturday the 29th has a dropping swell at 6ft from the WSW, still a decent 13-second period, with moderate energy (968). Again, light onshore wind in the morning, but it's surfable. By Sunday the 30th, it's fading fast to 4ft, and the rest of the first week and into the next is a slow grind of small, weak swells, mostly 3ft to 5ft, with cross-on winds and poor to marginal conditions.
Now, look ahead to Friday the 4th of September. The morning is still marginal with a 4ft SW swell (14-second period) and moderate energy (506), but the afternoon! The afternoon goes glassy. Wind drops to 3 mph from the W, and it's glassy. That's the standout. The swell is small but clean, with a decent 14-second period. It's a proper little window for a fun, uncrowded session. The combined energy is moderate (470). For that afternoon, it's your best bet.
Other than that Friday afternoon, the rest of the second week is more of the same – small, choppy, and uninspiring. Saturday the 5th and Sunday the 6th are marginal at best. So, be patient. The real highlight is that glassy Friday afternoon on the 4th of September. Hornitos is a consistent spot, so it won't stay quiet for long, but this run has a lot of waiting.
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.
