The Lowdown
Alright folks, Rusty here. Let’s get into it for Hornitos.
We’re looking at a pretty quiet start to the period. The first few days are a write-off for any decent waves. Sunday the 23rd through Tuesday the 25th are basically flat with tiny, weak swell and poor conditions. Don’t even bother paddling out. The water temp is a notable 65° – that’s 5° warmer than average for this time of year, so it’s feeling more like a bath than a typical surf session.
Wednesday the 26th morning gives us a small glimmer of hope. The swell is only 2ft from the SW, but the period is a long 14 seconds, and the wind is glassy – dead calm. It’s surfable, but still very ordinary. The combined energy is only 181 (weak), so it’s not going to have much push.
The real standout in this outlook is the Friday the 28th. We’ve got a solid 7ft groundswell from the SW in the morning, with a 15-second period. That’s serious energy – the combined energy reading is 1860 (strong). The wind is a light cross-onshore breeze, so it’s not perfect, but it’s workable. This is a big swell, over 8ft, so this one is strictly for experienced surfers only. The swell direction lines up with the optimum SW direction for Hornitos. This is the best on offer. Saturday the 29th still has some size at 6ft, but the wind is onshore and the energy is dropping.
After that, the surf fades back into marginal territory for the rest of the first week and into the second week. There’s another pulse of swell showing up around Friday the 4th of September, with 6ft from the WSW and a 16-second period, and another strong energy reading of 1809. That’s promising, but it’s a long way out. The wind is onshore, so keep an eye on it. The following Saturday the 5th also has some left-over 5ft swell.
To be honest, this forecast is a bit of a slow burner. A lot of the days are just not offering much. The two clear windows are the Friday the 28th and the Friday the 4th of September. The rest of the time, you’re looking at marginal, small, or onshore conditions. For a break that’s fairly consistent, it’s a bit of a bummer, but that’s how it goes sometimes.
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.
