The Lowdown
Alright folks, Rusty here. Let’s look at what’s cooking for Eerste Steen over the next couple of weeks. It’s a mixed bag, but there are some serious windows of opportunity if you pick your moments.
The water is sitting at 57°, which is a bit colder than normal for this time of year, so you’ll want that thick wetsuit if you’re heading out. The overall pattern starts slow, but we’ve got a couple of standouts that are worth circling on the calendar.
Kicking off on Tuesday the 4th, the morning session is the only real chance to start the week. We’ve got a clean 5ft SW groundswell with an 11-second period, the energy is moderate (484), and the wind is glassy from the ESE at just 3 mph. It’s not massive, but it’s clean. If you can get out Tuesday morning, the conditions will be nice. That afternoon, the wind swings to a cross-on and the quality drops.
Wednesday the 5th is a write-off. The swell jumps up to 7ft to 8ft, which you’d think would be good, but the wind is howling from the NNW at 15 mph, creating a messy cross-chop. The energy is getting fired up (1980 to 2315), but the surface is junk. No good.
Now, Thursday the 6th morning is the first real standout. The swell is 10ft from the WSW, with a 13-second period and a combined energy of 3425, so it’s got some punch. But the wind is a clean cross-off from the E at 6 mph, making for a clean face. This is only for experienced surfers though – 10ft is big, hollow, and powerful. The afternoon sees the wind shift to a cross, making it less appealing.
Friday the 7th morning stays big with a 10ft SW swell at 14 seconds, energy at 3601, and clean cross winds from the SSE. The afternoon bumps up to 12ft, which is pushing it at this break. It’s big, but the wind stays light. Not for the faint of heart.
Saturday the 8th drops back to a more manageable 8ft, but the wind is cross-on, so it’s not the best.
Sunday the 9th is a complete mess. The wind hits 28 mph with rain showers, and the swell is 12ft. It’s a blown-out, lumpy disaster. Stay on land.
We get a little breather on Monday the 10th. The swell drops to 7ft in the morning, and the wind is a clean cross-off from the ESE. The afternoon is even better with 6ft S swell and clean conditions, energy around 791. It’s not huge, but it’s surfable and clean.
Tuesday the 11th is small and weak. The morning is only 3ft from the S, and the period is a short 8 seconds. The afternoon has a weird 2ft swell with a 24-second period, which is super long and won’t produce much for a beach break.
Here’s the next big standout. Wednesday the 12th morning: 6ft SW groundswell at 18 seconds, with a clean offshore from the NE at 6 mph. The energy is strong (2190). That’s a beautiful combo. The afternoon holds at 7ft with the same quality. If you can get on it that Wednesday, it’s going to be excellent.
Thursday the 13th is also a top-shelf day. Morning has 8ft from the WSW, 17 seconds, and a cross-off from the NNE. The afternoon goes glassy with a 8ft swell and an SE wind at 3 mph. The energy is 2820. That afternoon session on Thursday the 13th is going to be a dream.
Friday the 14th morning is still good with a clean 6ft, but the afternoon gets a cross-on wind, so it’s a half-day.
The second week is a bit more of a gamble. The 15th and 16th are small to moderate, with the 16th afternoon seeing the swell bump back up to 10ft, but with a cross-on wind.
Monday the 17th morning is a massive spike: 13ft from the WSW with a 14-second period and an energy reading of 6398. That’s a huge amount of power. The wind is a cross-shore from the NNW at 9 mph, which makes it ridable, but only for the absolute best of the best. This is expert territory. The afternoon turns into a stormy mess with 18 mph winds.
The 18th and 19th settle back down to 8ft to 10ft, but the wind is either cross-off or light cross, making for some decent sessions if you’re picky.
Best bets: The standout is Thursday the 13th, especially the glassy afternoon session with 8ft WSW swell. The second best is Wednesday the 12th, with that clean 6ft to 7ft groundswell. If you’re an expert, Thursday the 6th morning and Monday the 17th morning are for you.
This is Rusty, signing off.

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.
