The Lowdown

Alright folks, Rusty here. Let’s look at what’s on the table for the next couple of weeks.

The first wave worth mentioning rolls in on Wednesday the 2nd of September, but it’s a slow start. The whole pattern is small, with a long-period groundswell from the SW, but the energy is just not turning into clean, rideable waves. Most of the time the wind is a light cross-onshore, or the surface is just a bit bumpy. The water is a warm 66°F – that’s about 5°F warmer than usual for this time of year, which is a nice bonus, but the waves are a struggle.

The first few days are a tease. Wednesday the 2nd has a tiny 2ft SW swell (394 combined energy), but it’s marginal. Thursday the 3rd sees a 2ft to 3ft SW swell with a 16 to 18-second period (410 to 470 combined energy), but the wind is light cross-onshore, so it’s a bit bumpy. Friday the 4th is the best of the early run, with a 4ft WSW swell, onshore wind easing to a slight air by afternoon, and 14-second periods (676 and 698 combined energy). The energy is moderate, good for a longboard or a funboard. The break is consistent, so it stays in the game, and the crowds are *sometimes* an issue, so you might have a few buddies out.

Saturday the 5th drops back to 3ft and 3ft, with the cross-onshore wind returning. Sunday the 6th is a total washout – poor surf conditions with a 2ft to 2ft SW swell. This run of nothing really worth paddling for continues through Monday the 7th, Tuesday the 8th, and Wednesday the 9th. The swell stays tiny, between 2ft and 3ft, and the wind is just enough to mess up the surface.

The real standout, if you can call it that, is Friday the 11th of September. The morning and afternoon both see a clean 2ft SW swell with a 13-second period. The combined energy is low (246 and 252), but the wind goes glassy. That’s a rare gift. For a longboard or a twin-fin, those little peelers will be clean, fun, and uncrowded. It’s not a big wave, but glassy conditions on a consistent break make it the best on offer.

Saturday the 12th of September also has a moment – the afternoon session shows a 3ft SW swell, a 12-second period, and expect good surf conditions. The wind is glassy, and with 271 combined energy, it’s a solid little window. The morning is cross-onshore, so the afternoon is the call.

After that, the quality drops hard. Sunday the 13th through to the end of the period, from the 13th to the 17th, we see a mix of poor and marginal conditions. The swell pops up to 3ft to 4ft on the 14th and 16th, but the period is short (8 to 10 seconds), the wind is cross-onshore or onshore, and the energy is moderate at best. The 15th of September has a 14-second period WSW swell hitting 3ft (553 combined energy), but it’s light cross-onshore, so the surface is bumpy. There’s nothing in the second week that compares to the glassy windows of the 11th and 12th.

So, if you’re looking to get wet, focus on the 11th and 12th of September. The waves are small, but the glass is clean, and the water is warm. That’s your best bet.

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.
