The Lowdown
Alright folks, let's get into it. Rusty here, and we're looking at a wild ride ahead for Horse Trails, a sandbar setup that’s fairly exposed to the southwest.
This forecast kicks off with a bang on Thursday the 3rd. The morning session is looking like the absolute standout of the whole run. We’ve got a solid 6ft groundswell rolling in from the southwest with a clean cross-off breeze. The combined energy is pumping at 1143 (moderate wave energy), and conditions are set to be clean. That morning is the one to circle.
But hold on to your board shorts, because things get messy real quick. By Thursday afternoon, the wind howls up to 28 mph from the SSE, turning the 12ft swell into a complete mess. That afternoon is a write-off.
Friday the 4th is also a tough one. The swell stays big, with 8ft in the morning and 10ft in the afternoon, but that strong breeze stays onshore and makes it unsurfable. Saturday the 5th is looking marginal, with a dropping swell but still dirty wind. Not your day.
Now, here’s the next real highlight. Sunday the 6th morning. We’ve got a 6ft southwest groundswell, but check out the period: 18 seconds. That is very long-period energy, packing a punch at 2435 (strong wave energy). The wind is light, but it's cross-off, keeping things clean. This is prime for the more experienced crew, but that long period will make it a bit wonky for the beach breaks.
The next week is a mixed bag of onshore winds and dropping swell, with a few flashes of hope. Monday the 7th is okay, but that wind is cross-shore. Tuesday the 8th and Wednesday the 9th are small and messy.
The next standout pops up a week away, on Saturday the 12th. Morning has a 8ft SW swell with a clean cross-off breeze – a bit big but rideable for the keen. Then, on Sunday the 13th morning, we get some glass. The wind goes to nothing—completely glassy—with a 4ft SW swell at 12 seconds and an energy of 1028 (moderate). That is a true window of perfection for the skilled surfer who can handle a bit of size from the day before.
After that, it’s a slow fade into smaller, cleaner waves for the middle of the following week, with a small 3ft groundswell on Tuesday the 15th and Wednesday the 16th, but with variable wind. The very end of the run, on Thursday the 17th, sees a huge 12ft SW swell pop up, but the cross-shore wind will be howling. That’s strictly for the big-wave chargers, or frankly, the kite surfers, because that setup will be a washing machine for a paddle board.
Best on offer:
- Thursday morning (Sep 3): 6ft SW, 1143 energy, clean cross-off breeze. The classic start.
- Sunday morning (Sep 6): 6ft SW at 18 seconds, 2435 energy, light cross-off. For the experienced, a serious groundswell treat.
- Sunday morning (Sep 13): 4ft SW, 1028 energy, completely glassy. A rare moment of perfection.

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.
