The Lowdown
Alright folks, Rusty here. Let's have a look at what's cooking for this stretch.
We’re looking at a solid run of swell hitting Haardebaai, a reef break for the advanced crew. The water temp is sitting around 60°, which is pretty much spot on for this time of year, no surprises there.
The action kicks off Tuesday the 21st. The morning session is where it’s at. We've got a 8 ft SW groundswell with a long 14-second period and a glassy north breeze. The energy is pumping hard at 2750 (moderate to strong), and it’s going to be clean as a whistle. This is a standout session for experienced surfers only. The afternoon sees the wind shift cross-on and the swell bumping up to 10 ft, but the quality drops.
Wednesday the 22nd looks good too. Clean, moderate offshore winds from the NW all day. Swell holds around 7 ft to 7 ft from the SW with a period of 12 seconds. Wave energy is solid (1454-1480). Good, clean waves for the skilled surfer.
Thursday the 23rd has a tricky morning with strong cross-off winds, but the afternoon is a ripper. The wind goes offshore from the NNW, the swell bumps back up to 8 ft SW with a 13-second period, and the energy jumps to a massive 3971 (strong). This is another standout session for the experienced. Clean, powerful lines.
Friday the 24th the swell gets serious, hitting 12 ft SW, but the wind turns onshore and cross-on. The energy is huge (5529-4555), but it’s going to be a messy beast. This is more of a kitesurfer’s dream than a paddle surfer’s unless you’re a total charger. The weekend (25th-26th) stays lumpy and onshore with dropping swell. The gap in quality lasts through Monday the 27th with strong cross-shore winds and rain showers making a mess of things.
Then we hit the best window of the whole run. Tuesday the 28th is an absolute standout. We’ve got a massive 13 ft SW/SSW swell with a 14-15 second period. The wind is light and cross-off, and the wave energy is off the charts at over 6000 (very strong). This is big, powerful, and clean. Experts only. Wednesday the 29th and Thursday the 30th are nearly as good. Wednesday has 10 ft SW with light offshore winds and clean conditions. Thursday the 30th is magic: glassy conditions with a 8 ft SW swell and a very long 16-second period. The energy is 3412 (strong). That long period means it’ll be walling up nicely at this reef, with long lulls between sets. Brilliant.
Friday the 31st offers one last clean morning with offshore winds and 7 ft swell before things go a bit sideways. The first week of August turns into a wind battle. Saturday the 1st is blown out with onshore gales. Sunday the 2nd bounces back with clean cross-off and offshore winds and a big 13 ft S swell, but it’s a week and a half out, so treat it as promising but less certain. Monday the 3rd through Tuesday the 4th are a write-off with near gale-force winds, despite the swell.
The real standout for this whole period is Tuesday the 28th and Wednesday the 29th. Massive, powerful, clean groundswell at Haardebaai for the experts. If you’re good enough, those are the days.

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