The Lowdown

Alright folks, Rusty here. Let’s get into it for Hornitos.

We’ve got a bit of a wait ahead. The first half of this outlook is pretty grim, with a couple of days of nothing really worth paddling out for. The main action starts to build from Friday the 28th of August, but even then it’s a bit of a mixed bag.

Let’s start with the water. Right now, the temperature is about average for this time of year – nothing unusual, so just a normal wetsuit will do.

The first real chance to get wet is Friday morning, the 28th of August. There’s a 7ft swell from the southwest, with a period of 15 seconds – that’s a proper long-period groundswell. The energy is strong (1810), so there’s plenty of push. The wind is light and from the west, which is onshore, but it’s a light breeze. The main issue is that the forecast is marginal, with questionable tide conditions. It’s big enough that beginners might want to sit this one out. The afternoon sees the swell drop a touch to 7ft, with a bit of cross-onshore wind, so it’ll be a bit lumpy but still rideable for the experienced crew.

Then Saturday the 29th of August, the swell settles to 6ft in the morning, again from the southwest, with a 13-second period. The energy is moderate (968). The wind is light and onshore so it’s not clean, but the size is more manageable. The afternoon is a little smaller at 5ft, and the cross-onshore breeze will leave some ripples on the face.

After that, the swell really drops off. From Sunday the 30th of August all the way through Wednesday the 2nd of September, the surf is mostly poor. The swell height hangs around 4ft to 5ft, with short periods and weak energy, and the wind stays cross-onshore. It’s just not doing much.

There’s a tiny blip on Wednesday the 2nd of September morning – a 1ft swell but with a 19-second period, which is a very long period for such a small wave. The energy is weak (270) so it’ll be a real gutless, slow wave. Not worth the paddle.

The end of the window, from the 3rd of September onwards, things get a bit more interesting, but it’s still marginal. The swell picks up a little, but the wind is often cross-onshore or onshore. The best-looking morning might be Monday the 7th of September, with a 4ft swell from the southwest, a 12-second period, and a light westerly wind that’s onshore but very light. The energy is moderate (684). Still, it’s a marginal forecast.

The true standout, if you’re an experienced surfer and don’t mind the wind, is Friday the 28th of August. The 7ft, 15-second swell from the southwest is the biggest and most energetic of the whole run. For the rest, it’s a lot of waiting and hoping for cleaner conditions.

Stay patient, and keep an eye on the wind.

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.
