The Lowdown
Righto folks, Rusty here. Let’s have a proper look at the coming weeks for Alkantstrand.
Alright, the overall pattern is a bit of a mixed bag. We’ve got some sizeable swell on the way, but it’s going to be a challenge for this spot. The early call looks to have a few solid but tricky days, then a long quiet spell before a glimmer of hope right at the very end.
Kicking off on Thursday the 20th of August morning. It’s not going to be pretty. We’ve got a 8ft swell from the SSW with a short 7-second period. The combined energy is moderate (799). The wind is a strong offshore, so it’ll be blown clean, but that’s a lot of water for Alkantstrand. This is strictly for the experienced crew only. The water temp is sitting at 71°F, which is pretty average for this time of year.
Come Friday the 21st of August morning, there’s still a 6ft S swell but it’s got a very long 14-second period. That’s proper groundswell energy, with combined energy up to strong (1172). But the wind is onshore and it’s just not looking clean at all.
The standout period is going to be Sunday the 23rd of August. Morning has a solid 8ft S swell with a moderate 11-second period, and a fresh 30 km/h offshore wind from the SSW. The combined energy is very strong (1717). The afternoon cleans up a touch, 7ft S swell with a 10-second period and a lighter cross-off wind. Again, this is expert territory due to the size.
After that, it goes pretty quiet. There’s a long stretch from Monday the 24th of August right through to the 31st of August where the surf quality is mostly poor. There is a tiny, tiny option on Tuesday the 25th of August afternoon with a 3ft S swell and a very long 16-second period in clean, light cross-off winds, but it’s barely a ripple and the combined energy is weak (462).
The next real chance comes on Tuesday the 1st of September afternoon. We’re looking at a cleaner 6ft SSW swell with a short 6-second period, combined energy is moderate (328), with a clean cross-off wind. Then into Wednesday the 2nd of September morning: a light 10 km/h offshore wind and a 4ft S swell. The combined energy is weak (247), but the wind is right and the waves should be clean.
That’s your look, mates. A few big, expert-only days early on, then a long wait for some small, clean windows right at the end.
Rusty.

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.
