The Lowdown
Right, mate, Rusty here with a look at what's on offer at Horse Trails. We've got a solid run of surf stretching over the next couple of weeks, but it's a bit of a mixed bag, so you've got to pick your moments.
The good news is we're looking at a decent run of south-west groundswell, and the water's sitting at 56° which is much colder than normal for this time of year - you'll definitely feel that nip, so a 4/3 is the go. The first real standout is the coming Tuesday, the 11th of August. The morning starts with a clean 7ft swell from the SSW, with a solid 12-second period, and a cross-off breeze. The afternoon cleans up even more with light winds and 5ft. The energy is building nicely too, with moderate readings. This is a great window for the intermediate crew.
We then hit a few days where it's clean but the conditions are a bit "marginal" - the Wednesday and Thursday still have decent swell (6ft to 8ft) from the SW, and the winds stay cross-off, but the forecast scores aren't peak. The real magic shows up on Saturday the 15th of August. Morning and afternoon are both glassy - dead calm - with a consistent 6ft swell from the WSW at 14 seconds. That's your pick of the first week; just a clean, fun sandbar with no wind to mess it up. The energy is moderate, and it's a fairly consistent break, so you'll get waves.
Sunday the 16th starts glassy again with 5ft, but the afternoon brings a light cross-onshore chop. The week that follows gets bigger, with the swell pushing 8ft to 10ft and the winds picking up from the SSE. By Tuesday the 18th of August, we're looking at 10ft SW swell, but that's getting too big for this break, and with a moderate cross-shore it's not going to be clean. The energy is very strong. That setup looks more interesting for kite surfing than paddle surfing, truth be told.
We get a bit of a lull around the 20th with smaller 5ft-6ft surf and cleaner cross-off winds, but the wind swings onshore on the 21st and 22nd with more lumpy conditions. The window opens again on Sunday the 23rd of August with clean 6ft surf and light winds, and then the final standout is Monday the 24th of August. The morning offers excellent conditions for experienced surfers: 8ft of SW groundswell at 14 seconds, with clean offshore winds from the NE. That's a serious groundswell with strong energy, and with offshores, it'll be well-shaped. That's your pick of the second week. The last day on the 26th looks glassy again but with a shorter 10-second period and smaller 6ft swell.
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.
