The Lowdown
Alright, Rusty here to break it down.
We got a good stretch of swell lined up for Horse Trails that’ll keep things interesting for the next couple weeks. The water’s way colder than normal, coming in near 55°F, so that’s about a 5°F drop from average – you’ll definitely feel that chill. Kicking off on Saturday the 15th, the morning is where it’s at: dead calm wind, 1.7m (so about 6ft) of WSW swell with some real energy (1100), giving you clean, shapely walls. Not huge, but clean.
Saturday afternoon goes a bit sideways with a light cross-onshore, but Sunday the 16th morning is your real highlight – swell pushing 1.9m (roughly 6ft), a 14-second groundswell, with a light cross-off breeze keeping it tidy. That is a proper session for the experienced surfer. That energy (1403) tells you it’s got punch.
Monday the 17th stays decently sized at 2.5m (about 8ft) but the wind goes cross, so it’s a bit lumpier. Through Tuesday to Thursday, the swell drops back to the 1.8m to 2.1m range (6ft to 7ft), but the wind stays messy. You can still get waves, but it's work.
Friday the 21st morning goes glassy again with 1.7m (6ft) swell and dead calm – that’s a sneaky clean, smaller day you won’t want to miss if you like it smooth.
Now hold on for Saturday the 22nd – the swell blows up to 3.5m (12ft) and then 4.5m (15ft) with 30 km/h (about 19 mph) winds. That is big, heavy, raw – a sandbar in those conditions will be a washing machine. That’s for experts, or honestly, better suited for the kite crew. That energy reading at 7213 is huge.
Sunday the 23rd stays massive and unruly. By Monday the 24th, it backs down to a still-chunky but more manageable 2.5m (8ft) with light cross-off wind – good for experienced folks again. Tuesday the 25th morning is lower at 1.8m (6ft) with clean conditions.
Late in the run, from the 27th on, it gets progressively weaker and choppier, though the 28th morning offers one last glassy moment at 2.5m (8ft) with a clean SW swell.
All said, the best bets are the mornings of Saturday the 15th, Sunday the 16th, Friday the 21st, and Monday the 24th. For my money, Sunday the 16th morning is the pick of the lot – solid size, clean wind, and that long period swell from the right direction.

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.
