Table - best surf conditions forecast for Hornitos over the next 16 days.
Alright, let’s break it down. The next couple of weeks at Hornitos have a short window of really clean surf, followed by a long dry spell, so we’ve got to be smart about it.
The best bet is Tuesday, 14 July. Tuesday morning we’ve got a clean 4ft swell from the WSW with a 15-second period, and the wind is dead glassy. The combined energy is solid (804), so the waves will have some real punch. Tuesday afternoon is just as good, with 5ft from the SW and still glassy. This is the top pick by a long shot. Water temp is 17°, which is about normal for the season.
The surrounding days are a letdown. Monday 13 July is small and weak with cross-on wind, not worth it. Wednesday 15 July and Thursday 16 July have some size but the wind is cross-on, so it’s messy. Friday 17 July morning is flat, but the afternoon offers a surprise: a glassy 4ft from the SW with a 12-second period and moderate energy (394). That’s a sneaky good session.
Saturday 18 July has a glassy afternoon with 4ft from the WSW, but the period is shorter at 10 seconds, so it’ll be a bit less powerful.
Then it goes dead. From Sunday 19 July through Monday 27 July, the forecast is consistently poor. Wind is cross-on or onshore, the swell drops, and the energy readings are low. That’s a stretch of about 9 days with nothing worth paddling for. There’s a small bump on Thursday 23 July with 4ft from the SW, but the wind is cross-on and the period is only 9 seconds, so it’ll be weak and choppy.
The very end of the outlook, around Tuesday 28 July, shows a little more life: 3ft to 3ft from the WSW with a 12-second period and light winds, but it’s still marginal. Not a standout, but a sign things might be turning.
So, the clear winner is Tuesday, 14 July – get out there early for the cleanest, most powerful surf of the whole run.

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.
