The Lowdown
Alright folks, Rusty here. Let’s talk about what’s coming up for Eerste Steen. The water’s a bit cooler than usual for this time of year, sitting at 57°, which is a touch nippy. It’s a fairly consistent little set-up here, exposed to the SW, and it likes a good SW swell. There’s a solid run of surf on the way, but not all of it is going to be easy going.
The first real tease starts on Thursday the 23rd. The morning has a bit of wildness to it – cross-off wind from the NNW at 19 mph, and a 6 ft SW swell. The energy is ramping up (1123), but it’s a bit messy and the light rain doesn’t help. It’s a marginal call. But then, Thursday afternoon things clean right up. The wind drops to an absolute glassy 3 mph, and the swell pushes to 7 ft from the SW with a nice 11-second period. The energy jumps to 1586. This is where it gets good. That’s clean, glassy, and punchy. For an experienced surfer, this is a real treat.
Friday the 24th is a different beast. The morning swell is way up – 12 ft from the SW with a 14-second period, and the energy is massive at 4362. The wind is glassy, but that’s a lot of water. Over 8 ft, this is for experts only. By the afternoon, the wind swings to a cross-on SSW at 9 mph, and while the swell drops to 10 ft, it gets a bit choppy. The morning is the standout if you’ve got the nerve.
Saturday the 25th morning is back to being a great option. The swell settles at 7 ft from the SW, 13-second period, and the ESE wind is a light cross-off at 6 mph. The energy is solid at 1843. It’s clean, powerful, and well-shaped. That’s your best bet for the weekend. The afternoon gets a bit sloppy with a cross-on wind.
Sunday the 26th morning is another glassy session with a 7 ft SW swell and 11-second period. The energy is 1322. It’s clean and inviting. The afternoon turns cross-on and loses a bit of quality.
After Sunday, things get a bit rough. The wind picks up hard through Monday and Tuesday, with strong breezes and big, messy cross-chop. The swell sticks around but the quality drops. By Wednesday the 30th, the swell bottoms out to 5 ft, and the energy is weak (634) with lumpy cross-shore wind. It’s a quiet spell right through the end of July and into the start of August. The first week of August is small, mostly 3 ft to 4 ft SW swell, with light winds and glassy mornings. It’s fun for a longboard or a fish, but nothing to get too excited about.
Then, look out for Tuesday the 4th of August. The swell starts to build again. The morning sees a 6 ft SW swell with a very long 17-second period, and the energy rockets to 3511. The wind is a light cross. That’s a lot of power and a very long wait between sets. It’s a bit tricky. By Wednesday the 5th, it’s huge. The morning has a 13 ft SW swell, 17-second period, and a staggering 9718 energy. The wind is a gentle cross-shore, but that’s a monster. Over 13 ft, it’s a serious, heavy, expert-only situation. The afternoon is the same size. That’s the standout of the whole forecast, but it’s for the brave and the skilled. After that, it drops back down through the 6th and 7th, but the wind gets messy again.
So, if you’re looking for the best of the bunch: Thursday the 23rd afternoon is a glassy, clean 7 ft, and Saturday the 25th morning is a clean 7 ft with a nice off-shore feel. If you’re an expert and want the biggest, meanest waves, Wednesday the 5th of August is where it’s at, but it’s a long way off and forecasts can shift.

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.
