The Lowdown
G’day, Rusty here. We’ve got a bit of a mixed bag coming up for Eerste Steen. The water’s sitting at 55°, which is much colder than normal for this time of year – nearly three degrees off, so you’ll want a good steamer.
Right now, we’re in a quiet spell. The first real chance to get wet won’t be until Wednesday morning, the 2nd of September. There’s a solid 10ft SW groundswell rolling in, with a long 14-second period and moderate wave energy (3398). The wind’s light and cross-shore, so it’ll be a bit bumpy but rideable for intermediates. That’s a fair bit of size though – over 8ft, so this one’s for the experienced crew only. It stays big into the afternoon, but the wind swings cross-onshore and chops it up.
Thursday the 3rd of September is a true standout, but only if you’re a serious charger. The swell jumps to a massive 20ft from the SW, with a very long 12-second period and extreme energy (10208). The wind is clean and cross-offshore in the morning – perfect conditions for a wave this size. But let’s be real, that’s way over 8ft; it’s only for expert surfers, and even then, it’s heavy. The afternoon drops to 16ft, still huge.
After that, things settle down fast. Friday the 4th has a 7ft S swell with moderate energy (1379) and clean cross-off wind, but it’s a short 10-second period – less push. By the weekend, we’re dropping to 3ft and smaller, with clean but weak conditions. Crowds are possible here at Eerste Steen, as it’s a fairly consistent spot that draws a few locals when the swell’s on.
Then we hit a long flat spell. From Saturday afternoon the 5th right through to the 11th of September, there’s barely anything worth paddling for – just knee-high dribble and onshore slop. A little bump shows up on Sunday the 6th with 5ft SW groundswell and a very long 15-second period, glassy morning winds, and clean conditions – that’s a nice little window for a more relaxed session, but the energy is only moderate (980). After that, it’s mostly small and messy until the 13th of September, when a 7ft SSE windswell with short 8-second period and moderate energy (1015) shows up under clean cross-off wind – surfable but nothing to write home about.
Overall, the best on offer is that Thursday morning session on the 3rd of September for experts, and the Sunday morning glass-off on the 6th for anyone wanting clean, manageable waves.
Rusty.

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.
