The Lowdown
Alright, surfers, Rusty here. Let's have a look at what's on the cards for the next couple of weeks.
We've got a real mixed bag coming up, but there's some serious firepower on the horizon if you're an experienced surfer. The first few days are a bit of a tease, but the end of the week and into the next one holds some real promise, along with some periods of proper grunt.
Kicking off on Tuesday, July 21st, the morning is your best bet early on. Eerste Steen is looking glassy with a clean 7 ft SW swell. The water is sitting at 14°, which is a bit colder than usual for this time of year. The combined energy is solid at 1946 (moderate wave energy), and with that light E wind, the conditions are going to be pristine. This is one for the experienced guys, as it's a decent size and the quality is there. The afternoon gets a bit lumpy with a cross-onshore breeze, so make the most of that morning window.
Wednesday and Thursday see the swell drop a little, but the wind is a bit of a factor. Wednesday morning (July 22nd) has a 7 ft SW swell, but a cross-onshore wind keeps it from being clean. Thursday afternoon (July 23rd) is a better shout with a 8 ft SW swell and a clean cross-offshore breeze and a big energy jump to 2493 (moderate wave energy). That's a good session for the experienced crew.
Now, Friday July 24th is where it gets interesting. The morning has a massive 12 ft SW groundswell with a very long 15-second period, and the energy is an enormous 4815 (strong to very strong wave energy). It's clean, but that's a lot of water moving. This is strictly for experts only, and honestly, it might be too big for the break itself. The afternoon is still huge at 10 ft.
Saturday July 25th morning is the standout of the first week. You've got a clean 8 ft SW swell, a 13-second period, and a clean cross-off breeze. The energy is at 2764 (strong wave energy). This is a classic, powerful SW groundswell with perfect conditions. For the experienced surfer, this is the one to circle. With Eerste Steen being fairly exposed and crowds said to be "sometimes", you'll likely have some company, but the quality will be worth it.
Sunday July 26th morning is another glassy beauty with a 7 ft SW swell, but after that, things go a bit sideways. Monday and Tuesday of the following week (July 27th and 28th) are blown out by strong winds. Tuesday has another massive 12 ft SW groundswell, but the wind is howling, making it unsurfable.
Looking further ahead, there's a flicker of hope. Friday August 1st morning has a glassy 6 ft SW swell, and the very next day, Saturday August 2nd morning, also looks clean with a similar sized swell. The energy is a more manageable 1622 to 1729 (moderate wave energy). The confidence is lower this far out, but it's a promising pattern.
After that, it looks like a bit of a lull. The first week of August is pretty weak and windy, with the swell dropping off and messy conditions. It's a typical blank run for the area when the big swells fade.
So, to wrap it up: if you're an experienced surfer, the absolute pick of the forecast is Saturday July 25th morning. For a slightly smaller but still excellent option, the glassy mornings of Friday August 1st and Saturday August 2nd are worth keeping an eye on.

Information about the Eerste Steen Surf forecast
The above surf forecast table for Eerste Steen provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Eerste Steen can be found by selecting the local surf guide option on the grey menu. Our Eerste Steen 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 (Eerste Steen) 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 Eerste Steen 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.
Eerste Steen 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.
