Table - best surf conditions forecast for Hornitos over the next 16 days.


G'day, I'm Rusty, and here's the skinny on the surf ahead for Hornitos over the next 16 days.

Alright, let's get to it. The coming week is looking like a bit of a mixed bag, but there are a couple of windows where it's worth paddling out. The water is sitting at a pretty normal 62° for this time of year, so no drama there.

We kick off Thursday, July 9th, with some small, clean lines from the SW. The swell is around 3ft, but it's a long-period groundswell at 16 seconds, which gives it some real grunt for its size, with a combined energy of 450. The morning is glassy with a light offshore, but the afternoon gets a bit of a cross-on breeze. It's not a total write-off, but you'll be working for those waves.

Friday, July 10th, is where it starts to get interesting. The morning is an absolute dream with glassy conditions and a 3ft SW swell at 13 seconds. The energy is moderate at 569, and the offshore wind is making it clean. This is your best bet for the first few days. The afternoon stays glassy, just a fraction smaller.

The weekend is a bit of a dud. Saturday, July 11th, sees the swell drop and a cross-on breeze messing things up. Sunday, July 12th, is similar, with onshore winds in the morning.

Monday, July 13th, is a write-off in the morning, but the afternoon turns glassy again with a small 2ft SSW swell. It's nothing special, but it's surfable if you're desperate.

The real standout arrives on Wednesday, July 15th. The afternoon has clean, glassy conditions with a 5ft SW swell at 13 seconds. The combined energy is a solid 611, which is starting to get into the moderate zone. This is good, clean, intermediate surf. The morning is a bit onshore, but that afternoon session is the pick of the first week.

Thursday, July 16th, offers another glassy afternoon with a 3ft SW swell. It's a smaller version of the day before, but still clean.

Now, look ahead to the second week. We get a bit of a pulse, but it's a bit of a gamble. Saturday, July 18th, and Sunday, July 19th, both see swell push up to 5ft to 6ft from the WSW, but the winds are mostly onshore or cross-on. This is too big for beginners and is moving into expert territory, but the wind is messy. The combined energy is strong, hitting 863 on the Sunday afternoon, but the onshore wind will make it lumpy. It might be more of a kite-surfing day than a clean paddle session.

The week after that, from July 21st, the swell drops off again and the wind remains a problem. There's a brief, glassy moment on the morning of Thursday, July 23rd, with a tiny 3ft SW swell, but the period is a short 8 seconds, so it's weak and won't have much shape.

Honestly, the best surf on offer is that glassy afternoon on Wednesday, July 15th, at Hornitos. The 5ft SW groundswell with clean conditions is the standout. The Friday morning of July 10th is a close second for its perfect conditions on a smaller swell. The bigger days around the 18th and 19th look promising in size but are let down by the wind.

Keep an eye on the forecast, because it tends not to stay quiet for long around here.

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.
