The Lowdown
Alright, Rusty here. Let’s get into what’s cooking for Horse Trails.
We’re looking at a solid run of surf ahead, but it’s a mixed bag. The water is sitting at 55°F – that’s a good 5°F colder than what’s normal for this time of year, so you’ll be wanting a thick wetsuit if you’re paddling out.
The real standout is Thursday morning, September 3rd. It’s clean, the wind is a light cross-offshore at 6 mph from the SE, and we’ve got a 6ft groundswell rolling in from the WSW with a 13-second period. The combined energy is moderate at 1138, but the quality is there – expect very good conditions. It’s not too big, not too small, and that wind will keep the face smooth. This is the session to target.
Now, the afternoon of the 3rd gets messy. The swell jumps to 12ft from the S with a shorter 9-second period, and the wind cranks up to 28 mph cross-off. That’s big and bumpy – more for the kite crew than a paddle surfer. The energy reading hits 2326, but with that wind, it’s a battle.
Friday the 4th through the weekend is a write-off. The swell stays too big (8ft to 10ft), and the wind is strong – 22 to 25 mph. The setup looks more interesting for kite surfing than paddle surfing. Keep the board in the car.
We get a break on Sunday the 6th. Sunday morning, September 6th is the other standout. It’s clean, with a gentle 9 mph cross-off breeze from the ESE, and a 7ft SW groundswell with a very long 18-second period. That’s serious energy (2719), and the period is long enough to create some proper, powerful lines. This is excellent for experienced surfers – the size and power will push you, but the conditions are right. The long period might make it a bit straight at the beach, but Horse Trails handles it well.
Sunday afternoon drops off slightly, and then from Monday the 7th through the middle of the week, the surf fades. Swells drop below 7ft, wind turns onshore or cross-onshore, and the conditions become marginal. There are a few clean windows on the 12th and 13th with 6ft to 4ft SW swell and light cross-off winds, but nothing that will have you cancelling plans.
The second week gets real interesting but less certain. Sunday morning, September 13th is a promising call – clean, light wind, 6ft SW groundswell at 13 seconds. The energy is strong at 1893. It’s a good session for experienced surfers if the forecast holds. Then, from the 17th into the 18th, the swell absolutely hammers in: 10ft to 16ft, with energy readings over 11,000. That’s very strong to extreme energy, but it’s way too big for most. The wind is fresh to strong, so expect lumpy, challenging conditions. Only for the brave or the kited out.
Crowds? At Horse Trails, they are sometimes a factor, but with the conditions being hit or miss, you’ll find your own peak if you pick the right window.

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.
