The Lowdown
Alright, Rusty here. Let’s break it down.
We’ve got a solid run of waves coming up at Alkantstrand, but it’s not all smooth sailing. The water temp is about average for this time of year, so no surprises there.
The first few days are building nicely. Wednesday morning, the 12th of August, we’ve got a chunky 12ft swell from the SE, but it’s a cross-shore wind and the forecast reckons it’s just too big for this spot. That’s a pass for me. The afternoon sees it drop a touch to 10ft with a cleaner cross-offshore breeze, but still too much juice for a comfortable session.
Things get real good from Thursday morning, the 13th of August. The swell drops to a much more manageable 7ft from the ESE, and we’ve got a clean offshore wind from the SW. The wave energy is still moderate (785), and the conditions are set up for a quality session. The afternoon is even better for the beginner crew: 4ft from the east with light cross-offshore winds (541). This is the standout.
Friday morning, the 14th, is the absolute pick of the week. Glassy conditions with a 5ft ESE swell and a light SSW breeze. The wave energy is moderate (523), and it’s going to be clean and crisp. The period is 8 seconds, so it’s a bit short, but with that wind, it’ll be fun. The afternoon gets a bit messy with a cross-onshore breeze.
After that, it’s a bit of a mixed bag. Saturday the 15th and Sunday the 16th have onshore and cross-onshore winds, making it choppy and poor. The swell sticks around 6-6ft from the east. The wave energy is moderate to strong (585-776), but the wind is the enemy.
Monday the 17th to Tuesday the 18th is pretty ordinary. Onshore winds and a dropping swell. Not worth paddling out.
Wednesday the 19th sees a bit of a recovery with a 3ft easterly swell and a clean cross-offshore breeze, but it’s small. The afternoon has a short-period 6ft S swell that’s messy.
Thursday the 20th is a real highlight. Glassy conditions again, with a 5ft S swell. The energy is moderate (501), and it’ll be clean. This is a solid secondary option.
Friday the 21st has a small 3ft easterly swell with clean conditions in the morning, but the afternoon turns poor again.
Saturday the 22nd is a write-off. Strong onshore winds and a massive 4ft S swell with a very long 18-second period, but the wind is howling from the north at 25 km/h. The wave energy is massive (1812), but it’s going to be a washing machine. The afternoon is the same story.
Sunday the 23rd is the final standout. Glassy offshore winds and a 4ft S swell with a long 14-second period. The energy is moderate (630). This is the pick for the second week. The period is long, so it’ll be better on a point or reef, but the conditions will be clean.
Monday the 24th to Wednesday the 26th is a mess again. Strong onshore winds and fading swell. Not worth it.
Thursday the 27th is a small 4ft E swell with light cross-shore winds, but it’s marginal.
The best on offer: Thursday the 13th at 4ft E with light cross-offshore winds, and Sunday the 23rd at 4ft S with glassy conditions. Both are clean, have good energy, and are the true standouts.
Rusty.

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.
