The Lowdown

Alright folks, Rusty here. We’ve got a mixed bag of a forecast ahead for Hornitos. The water is sitting at about 65°F, which is *much warmer than normal* for this time of year – a proper anomaly of about 4°F – so you’ll be comfy in a spring suit or even a shorty.

Right now, things are flat. The first real week of this forecast is a bit of a write-off for anything decent. From Tuesday morning, August 25th, through to the end of the month, we’re looking at tiny, weak swell. The waves are mostly under 3 ft, with swell energy (combined energy of all swells directed here) barely cracking 90 to 393, which is weak. The wind is cross-on or onshore, and the commentary is all “poor” or “marginal.” It’s not worth paddling out for.

There is a bit of a pulse on Friday, August 28th, with a 7 ft swell from the SW, but it’s got a long 15-second period, which is a groundswell. The combined energy jumps to 1835, which is strong, but the wind is still cross-on. The surf quality is still only “marginal,” and that’s a big size for Hornitos – it’s likely going to be messy and tough. Saturday, August 29th, drops to 5 ft but the wind stays cross-on. Not great.

After that, we get a long dry spell where the swell drops back to 3 ft to 5 ft, still with mainly cross-on winds. The score is a 1 out of 10 for most of those days. Nothing to get excited about.

Then we hit a promising little window. The best standouts in the whole outlook are on Tuesday, September 8th, and Wednesday, September 9th. On the afternoon of the 8th, the wind turns glassy, and we get a 3 ft, 10-second period swell from the SW. The combined energy is 316, which is still moderate, but the glassy conditions will make it clean and fun for a small-wave board. The following day, Wednesday the 9th, the morning has a 2 ft swell from the SW with a longer 14-second period, but the wind is light cross-on. The afternoon of the 9th is the real highlight: the wind goes glassy again, and that 2 ft SW swell with the 14-second period will be clean and lined up. Combined energy is 389 – moderate, but the quality should be there. This is your best bet for a smooth, uncrowded session.

For the rest of the second week, size stays small (2 ft to 5 ft) and the wind is mostly cross-on. It’s not total rubbish, but nothing else stands out like those two glassy afternoons. The consistent theme here is that Hornitos needs a combo of glassy wind and a decent pulse to really work, and that’s finally arriving on the 8th and 9th of September.

Rusty, signing off.

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.
