The Lowdown
Alright, let’s break down what Hornitos has in store. We’re looking at a pretty quiet start here. The first several days are a write-off – small, weak, and just not happening. You’ve got basically nothing worthwhile until we get towards the end of August.
Looking at the overall picture, the standout for the whole 16-day stretch is Friday, August 28th. That morning, we see a jump in size with a 7ft swell from the SW. The energy is strong, coming in at (1967). Wind is light WSW, so it’s a touch cross-on, but we’re talking light wind ripples, not full-on chop. The period is 15 seconds, which makes it a decent groundswell – more push and shape. Because it’s a beach setup with that longer period, it might run a bit straight, but the size and energy are the best we’ll see. The afternoon stays solid with 7ft and (1690) energy. It’s not perfect, but it's by far the best on offer.
After that, we taper off. Saturday the 29th still has some size (6ft morning, 5ft afternoon) and moderate energy (968 and 784), but it’s still cross-on and gets a bit more mixed in quality. By Sunday the 30th, it drops back into the poor zone.
The first week of September limps along with mostly marginal, cross-on conditions and swell hanging around the 4ft range. The water temperature at Hornitos on that first Monday the 24th is 65°F, which is a significant 5°F warmer than average for this time of year – noticeably warm for anyone getting in.
For the big day on the 28th, that 7ft swell is pushing into the intermediate and expert range; beginners will find it too big. Crowds are listed as ‘sometimes,’ so you might get a few out, but it won't be packed.
There’s a long gap of weak, poor surf from the start right through until that Friday the 28th. After that, it’s more of a slow fade. No real standouts in the second week, just a few marginal windows that are worth keeping an eye on but nothing to get excited about right now.
The best advice? Point your board towards Hornitos on the morning of Friday, August 28th and make the most of that pulse.

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.
