The Lowdown

Alright, this is Rusty. Let’s talk about Hornitos.

Look, I’m not gonna lie to you – this 16-day stretch is a real test of patience. We’ve got a long, dry spell before anything decent shows up. For the first week, it’s pretty much a write-off. The swell is small, the wind is messy, and nothing is lining up. We’re looking at a gap of about six days with basically no surf worth paddling out for, from the start of the period right through to the end of the week.

Then, on Thursday, 20th August, things finally tease us. Thursday morning at Hornitos, the wind goes glassy – dead calm – and we get a clean 3 ft swell. The period is a long 14 seconds, so that’s proper groundswell energy, with combined energy at 340 (moderate). It's not big, but for a wave that’s fairly exposed to the SW, and with that glassy surface, it’s the one real highlight. The water temp feels about average for this time of year. The break is consistent, which helps, but it can get a crowd sometimes, so get in early.

After that brief moment of hope, the surf drops back into the doldrums for another week. Tiny waves, poor conditions, cross-onshore wind – it’s a real struggle. The energy stays weak, dipping below 100 (68 and 53) on the 23rd and 24th.

Now, hold onto your board, because there’s a glimmer way out there. On Friday, 28th August, we see a pulse of proper size: 5 ft swell in the morning, building to 6 ft in the afternoon from the WSW. That’s expert territory in the afternoon, with a combined energy of 1033 (very strong). The wind is offshore and light, so the waves should be clean, but this is 15 days away – keep your hopes tempered. The period is 13 seconds, so it’s got some grunt. This is the one to watch for the future, but don’t pin your weekend on it just yet.

So, the short story: Thursday, 20th August morning is your best bet for a clean, small-wave session. The 28th is a promising, big-swell end-of-range prospect. Everything else, you’re better off checking the wind forecast for a kite.

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.
