The Lowdown

G’day, Rusty here. Let’s be straight with you – this outlook for Hornitos is a bit of a quiet one, and honestly, it’s a frustrating stretch. The swell is hanging around, but it’s mostly small and the conditions are just not clicking into gear for a proper session. You’ll be looking at a long gap of poor surf before anything even starts to feel a little bit promising.

The first week is pretty much a write-off. From Saturday the 5th right through to Tuesday the 10th, the wave energy is moderate, with combined energy values ranging from 282 to 511, but the swell height is tiny – only 2ft to 3ft. The period is long, mostly 13 to 18 seconds, which usually means groundswell, but the size just isn’t there to make it worth getting wet. The wind is light and mostly onshore, so the surface won’t be glassy or clean. It’s marginal at best, and the scores reflect that – nothing to get excited about.

Then from Wednesday the 11th through to Friday the 18th, things get even worse. The wave energy drops, with combined energy values as low as 109, and the swell stays small, between 2ft and 4ft. The wind picks up on the 11th, with a moderate cross-onshore breeze at 12 mph, making it choppy and messy. The guidance says poor surf conditions, and honestly, that’s the truth. There’s a gap of about eight days where the surf is just not worth paddling out for.

The first real glimpse of hope comes on Saturday the 20th of September. The morning shows a 4ft swell from the SW, with a period of 12 seconds, and the wind is light and onshore. The combined energy is 381, which is moderate. It’s still marginal, but it’s the best-looking window in the whole 16-day forecast. The wind is light, so the surface might be okay, but it’s not a standout. The break is fairly exposed to the SW swell, and the optimum direction is SW, so it’s a good match. The crowd situation is “sometimes,” so you might have a few others out, but it’s not a zoo.

The water temperature is about average for this time of year, so no need for a thick wetsuit unless you run cold.

Look, if you’re desperate, the 20th is your best bet, but keep your expectations low. It’s not a day to call in sick for. The setup is a beach break, so with small swell and light wind, it’s more of a longboard or funboard kind of day. If the wind gets stronger, it could be more interesting for kite surfing than paddle surfing.

Hang in there, and check back in a few days – forecasts can change.

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.
