The Lowdown
Alright, folks, Rusty here. Let's be straight with you – this 16-day stretch for Hornitos is a tough one. We've got a long, mostly flat run ahead, so don't get your hopes up for any heroics. The water is sitting at a very warm 64.8°F and is running about 4.5°F warmer than usual for this time of year, which is pretty notable and great for a shorty or even a rash vest.
The first recommendation doesn't pop up until Friday, August 15th. Before that, the swell is just too weak and messy. That Friday, we've got a small pulse of 3ft SW swell with a 13-second period, wrapping in early with light offshore winds. Saturday the 16th has a touch more size at 3.5ft, but the energy is still weak. The best of this first window looks like Sunday morning, August 17th. It's still small at 3.5ft, but it's from the WSW with a clean texture.
Then things go pretty flat and ordinary for a while. The surf quality drops off through the week, with more of those light cross-onshore winds messing things up. There's a brief blip on Tuesday, August 19th, when the swell bumps to 4ft from the WSW, with moderate energy (600), but the wind is just not helping, and it stays choppy.
The weekend of August 23rd and 24th looks pretty grim, with swell dropping and periods shortening. We finally see a little life on Saturday, August 23rd with a clean, glassy morning. The swell is a tiny 2.5ft from the SW with a 9-second period, but at least it's clean and surfable. That's the best you're going to get for a while. After that, it's a long, slow fade into the second week. There's another glassy morning on Wednesday, August 27th, but the swell has faded to just 2.5ft. The long-range stuff into the end of August is looking weak and disappointing.
So, to sum it up: if you're desperate for a wave, get out early on Sunday the 17th or Saturday the 23rd. These are not classic days by any stretch, but with the clean conditions, they're the only real opportunities on the board. Everything else is a washout.

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.
