The Lowdown
Alright folks, Rusty here, looking at the next couple of weeks for Horse Trails. Let’s get into it.
Overall, this stretch starts with a lot of size and power, but the conditions are going to be the real boss for a while. We’ve got a run of days where the waves are solid, but the wind and swell direction just aren't playing nice for a clean paddle. It's not until we get a bit further out that things start to line up properly. The water is much colder than normal at 55°, so don't forget a decent winter steamer if you’re heading out.
Right out of the gate on Tuesday, September 1st, we’re looking at a solid 8ft to 10ft SW groundswell, with a period of 13 seconds and a huge amount of energy (2429-3208). The problem is it's blowing a cross-onshore, which is going to chop up that sandbar face. It's a bit of a mess, honestly.
Wednesday, September 2nd holds that same big 10ft SW swell (3169-2682 energy), and the wind does swing offshore in the afternoon. The forecast notes this is actually too big for this break. Over 8ft, this is expert-only territory, and even then, the power is going to be a handful.
Now, here’s a standout window. Thursday, September 3rd morning is your best bet in the near term. The swell drops to a more manageable 7ft from the WSW (1488 energy), and here’s the kicker: the wind goes glassy. Clean, smooth surface, that's what we live for. This is for experienced surfers only given the size, but for the crew that can handle it, it’s going to be the pick of the first week.
Friday and Saturday are smaller, around 5ft to 6ft, but stuck with a cross-offshore SE wind. It’s clean, but the swell energy is low (500-682) and the period is short, around 8-9 seconds, so the waves will be a bit weak and crumbly.
Sunday, September 6th afternoon sees a lull in size to 4ft, but a very long period 15-second SW groundswell rolls in. The energy picks up to 1098, but a long period swell like this might break a bit flat and straight across the sandbar here.
The next big event is looking good. On Wednesday, September 16th, we get a serious pulse. The afternoon shows a 8ft WSW groundswell with a period of 16 seconds and massive energy of 3703. The wind is forecast to go glassy. That's the standout of the entire period, but it's for experts only at that size. The morning earlier that day is also worth a mention with a 3ft, 19-second period WSW groundswell and clean cross-offshore wind. These two days are where the quality is for the crew who can handle it. Keep in mind that a very long period swell like that 19-second one is best on a point or reef, but if the sandbar has the right shape, it could be magic.
Honestly, if you can only paddle out once, the morning of Thursday, September 3rd is where the clean, glassy conditions and solid 7ft swell meet just right for the experienced surfer. The afternoon of Wednesday, September 16th is the big, powerful, glassy end game for experts.
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.
