The Lowdown
Alright, Rusty here. Let's talk about Horse Trails. We've got a bit of a mixed bag over the next couple of weeks, with a serious wait for the real good stuff.
Right off the bat, Tuesday morning the 25th is a bit of a tease. There's a solid 7ft SW groundswell rolling in with a long 14-second period and a chunky combined energy reading of 2074, but it’s just not coming together perfectly. The cross-off wind from the SSE at 12 mph will keep things reasonably clean, but the wave comment flags "marginal surf forecast or questionable tide conditions." The water's sitting at 56°, which is 5° colder than usual for this time of year; that's a pretty noticeable chill. The afternoon gets a bit messier with a cross-shore wind and a cross-chop, so it's not the best.
Wednesday the 26th is more promising. The swell drops to a more manageable 5ft from the WSW, and we get clean conditions in the morning with a light cross-off ESE breeze. It's a bit smaller, but the quality looks better with the "expect very good surf conditions" note. The afternoon is similar with a lighter breeze.
Thursday the 27th sees the wind switch onshore, killing the quality. That little run of decent surf is over pretty quickly. We then hit a long, dull stretch where the surf is marginal to poor. The wave heights stay small, often under 5ft, and when they do pick up late on the 29th, the wind is cross-onshore and messy. This lull runs right through to the end of August and into the first day of September.
Now, here's where things get wild. Around Tuesday the 1st of September, the swell really starts to stack up. By the afternoon, we're forecasting a 10ft SW swell. The guidance says the wind and tide are favorable, but the swell is predicted to be too big for this break. Wednesday the 2nd and Thursday the 3rd are even bigger - we're looking at 12ft and even 15ft SW/SSW swells with combined energy readings hitting 5296 and 5330. The wind is favorable (cross-off from the ESE, even glassy on the 3rd afternoon), but this is expert territory only, and the forecast notes it's simply too big for Horse Trails.
The standout is Friday the 4th of September. The swell has backed off to a very surfable 7ft from the SW, but the real story is the morning glass-off. The wind is glassy, and the wave comment says "excellent surf conditions for experienced surfers." This is the session to circle. The 7ft is a bit much for beginners, but for anyone comfortable in overhead surf, this is the pick of the whole forecast. The afternoon gets a little more mixed with a light cross-shore.
After that, we get a mix of small to moderate swell, with another notable window on the morning of Sunday the 6th of September - a clean 5ft SW groundswell with a 15-second period. After that, the run fades out into poor surf with onshore winds and dropping energy towards the 9th, so the second week really only has that one Friday 4th standout and a brief glimmer on that Sunday.
So, keep an eye on the 4th of September for the best chance of some truly clean, solid waves. The rest of the forecast is a waiting game.
Stay frothy,
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.
