The Lowdown
Alright folks, Rusty here. Let’s take a look at what’s coming up for Alkantstrand. We’ve got a 16-day window, and honestly, it’s a mixed bag. The first surf worth mentioning is a short window early on, but then we hit a long stretch of poor conditions before a few clean windows show up further out. There’s a big gap in the middle where the surf is just not happening.
The first real chance comes Tuesday, 18th August. Alkantstrand is seeing a 4 ft east swell, though it’s a short period at 9 seconds. The combined energy is moderate (304). The water temp is 71°, which is bang on average for this time of year. The big positive here is the wind: a fresh 30 km/h offshore from the SSW, so the morning will be clean. The afternoon backs off to a 20 km/h offshore with a 4 ft east swell, making for a solid, clean session. Crowds are just *sometimes* an issue here, so you’ll have space.
Then it gets ugly. Wednesday the 19th through to the end of the month is mostly a write-off. Strong onshore winds, messy swell, or just plain poor surf. There’s a standout on Thursday, 20th August, but it’s a big one. A 10 ft SSW swell with a short 8-second period barrels in, with combined energy in the strong range (1036). However, the wind is cross-offshore, keeping it clean. But mate, at over 8 ft, that’s expert territory only. Beginners, stay well clear. The afternoon sees a 7 ft swell from the south, still big and powerful.
We then have a huge gap from Thursday afternoon through to early the following week with no real recommendations. The wind is all over the place, mostly onshore, and the swell is either too big or too messy.
Finally, we get a glimmer late in the period. On Sunday, 30th August, the afternoon session shows a 5 ft ENE swell with a short 6-second period, but the wind turns light cross-offshore at 10 km/h from the SSW, making it clean. The energy is still weak (375). The best window of the whole outlook, however, is the very last session. Wednesday afternoon, 2nd September, a 3 ft SSW swell rolls in with a 14-second period, bringing long-period groundswell energy. The combined energy is moderate (688). The wind is a glassy 5 km/h offshore from the SW. This will be clean, lined up, and worth the wait. Mark it in your calendar as a promising one, but it’s far out so keep an eye on the charts.
Rusty, signing off.

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.
