The Lowdown
G'day, Rusty here.
Alright, let's have a look at what's cooking at Horse Trails. This sandbar setup is fairly consistent and picks up a solid SW groundswell. The water temp is sitting at 58°, which is about normal for this time of year, so no nasty surprises there.
The first real standout is Tuesday morning, July 21st. The sea is glassy, absolutely flat calm, with a clean 7ft SW groundswell rolling in on a 14-second period. That's a proper groundswell with heaps of energy (1946), and it's gonna be a beautiful session for experienced surfers. The conditions are just about perfect.
Things get a bit tricky from Tuesday afternoon through to Wednesday, with the wind shifting cross-on and the quality dropping off. We've got a few days of marginal stuff, but keep your eye on Thursday, July 23rd, in the afternoon. The wind is a clean cross-off, the swell is 8ft SW, and the energy is right up there (2407). It's a big one, but still manageable for the stronger paddlers. The waves will be clean and lined up.
Now, the big daddy is looming. Friday, July 24th, and again on Tuesday, July 28th, the swell is predicted to pump at 12ft SW with a 15-second period. That's a massive amount of energy (5089 and 5047). The wind is light, but honestly, that swell is too big for this break. Unless you're a proper charger, this is for experts only. The beach break might be a bit of a washing machine, but the power will be something else.
For a more accessible session, Saturday morning, July 25th, is a beauty. Clean cross-off wind, 8ft SW swell, and a solid 13-second period. The energy is still strong (3001), but the conditions are clean. It's an excellent session for experienced surfers again.
We then get a nice glassy period on Sunday morning, July 26th, with a 7ft SW swell. It's a bit smaller, but the glassy conditions will make it super fun and clean.
The outlook gets a bit messy after that. There's a good run of swell, but the wind is often cross-on or onshore. Monday, July 27th, is a write-off with rain showers and choppy seas. Wednesday morning, July 29th, is another glassy moment with a 8ft SW swell, so that's a solid pick for the experienced crew.
The first week of August sees a big spike again. Saturday, August 1st, and Sunday, August 2nd have 10ft to 12ft SW swell, but the winds are better, with some cross-off and clean conditions. Again, that's big, powerful surf for experts only. The energy is massive (2985 to 3269).
Unfortunately, the second week falls apart. From Monday, August 3rd, the wind howls from the NNW at 18-25 mph, and the swell drops right off. The conditions are poor, and the energy is weak. There's a few days of rain and heavy wind, so it's not worth paddling out. The whole run from the 3rd through to the 5th looks like a write-off, with no real quality on offer.
So, the two absolute standouts are Tuesday morning, July 21st, for the perfectly glassy conditions and a solid 7ft SW groundswell, and Thursday afternoon, July 23rd, for the clean, cross-off waves and a meaty 8ft swell. Get out there for those.
Rusty.

Information about the Horse Trails Surf forecast
The above surf forecast table for Horse Trails provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Horse Trails can be found by selecting the local surf guide option on the grey menu. Our Horse Trails 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 (Horse Trails) 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 Horse Trails 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.
Horse Trails is 8 km (5 miles) from the very large city of Robben Island. If you plan a holiday in Cape Town, look for hotels and other accommodation in Robben Island. Robben Island has rooms for a wide range of budgets as well as cheap car hire and transport links.
