The Lowdown
Alright, grab a coffee, I’ll walk you through it. The first week and a half is mostly a write-off for a decent surf at Alkantstrand. The wind is blowing hard onshore most days, and the swell is messy.
There’s one small chance on Friday the 11th of September. The morning shows a moderate offshore wind from the SW and a 1 ft east swell. Water temp is about 69°, which is a touch cooler than usual for the season – you’ll notice it. The overall energy is moderate (346). It’s clean but small, nothing to get excited about, just the only session where you won’t be fighting a total mess. The afternoon fades quickly.
From Saturday the 12th through to Wednesday the 23rd of September, it’s a long, bleak stretch. The wind is either howling onshore, the swell is lumpy, or both. The energy numbers jump around from moderate to strong, hitting up to 881 at times, but the quality is pure garbage – choppy, blown out, and not worth paddling out for a surfboard. On days like the 15th and 16th with that cross-onshore breeze and lumpy sea state, you’d have a way better time on a kite than a surfboard.
Now, listen up – the second week flips the script. Starting Thursday the 17th of September, the swell goes big. We’re talking an 12 ft south swell, with a strong offshore wind from the SW and SSW. The combined energy rockets up to 2241 (very strong). It’s offshore, clean, and packing a punch. But this is a beginner-friendly spot, and that size is way too much. Over 8 ft, so it’s strictly for experts. Even on Friday the 18th and Saturday the 19th, you’ve got 10 ft to 8 ft swells with a long 12-second period – that’s groundswell, which can make a beach break close out or run straight. It’s clean and powerful, but getting into those sets will be a real fight. That Thursday through Sunday stretch is the only true standout, but only if you’ve got the skill and the guts.
From Monday the 21st onward, the swell drops back down, but the wind stays tricky or onshore again, so the quality goes away quick.
Bottom line: this week? Forget it. Next week, from the 17th to the 20th, that’s your window for big, clean, powerful waves, but it’s an expert-only game. If that’s not your speed, sit tight and wait for the next run.

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