The Lowdown

Alright folks, Rusty here. Let's have a look at what's on the menu for the next couple of weeks at Hornitos.

We're looking at a slow start, but the second half of the forecast period has some real promise. The first few days are a bit of a write-off, with onshore wind messing things up, but if you're patient, there's a proper window of clean surf coming our way.

Alright, let's get into it. The first few days are a struggle. Wednesday the 22nd of July and Thursday the 23rd are a no-go. We've got a cross-onshore breeze from the SW and SSW, making for a choppy, messy surface. The swell is around 4ft to 5ft from the WSW and SW, but the wind is just ruining it. The combined wave energy is moderate (375 to 545), but it's not doing you any favours.

Friday the 24th is where things start to look up. The morning session is the standout early on. We get a glassy, clean surface with a light W wind. The swell is 4ft from the SW with a 9-second period. The combined energy is moderate (338), but it's clean. It's not huge, but it's rideable and the conditions will be good.

Saturday the 25th has a similar vibe. The afternoon is the pick, with a glassy WNW wind, 4ft of SW swell, and a longer 11-second period. The energy is moderate (432). The morning is a little bumpy, but the afternoon will be worth a paddle.

Sunday the 26th sees the swell drop to 2ft, but the period has stretched out to 15 seconds. That's a long period groundswell. The energy is moderate (443), but the wave height is pretty weak. It'll be small and clean, but you'll be hunting for the sets.

Monday the 27th and Tuesday the 28th see the swell start to build again, but the wind is still cross-onshore for most of it. The wave energy is climbing into the strong range (611 to 712), and the period is long (15-17 seconds), but the wind is holding it back. Monday morning has a rare offshore wind, which is promising, but the conditions are described as unknown.

Now, here's the big one. The real standout is the window from Sunday the 2nd of August through Monday the 3rd of August. This is the best surf on offer. Sunday morning we have glassy conditions, 4ft of SW swell with a very long 15-second period, and the combined wave energy is very strong (879). The afternoon gets even better: 5ft of SW swell, 14-second period, glassy, and the energy spikes to 1099. This is proper, clean, powerful groundswell. Monday morning continues the run with 5ft of SW swell, 13-second period, glassy, and strong energy (826). This is the time to be in the water. A long period SW swell like this will wrap nicely into the point.

Tuesday the 4th of August is still good, with the afternoon offering glassy conditions and 4ft of SW swell. The energy is moderate (491). After that, the swell fades a bit into Wednesday and Thursday the 6th, with the energy dropping to low levels (102). It's a bit of a fade-out.

So, to sum it up: the first week is patchy, but don't get discouraged. The true gold is the 2nd and 3rd of August. That's where you'll find the best, cleanest, most powerful surf of the whole outlook. The rest is more of a gamble with 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.
