The Lowdown
Alright folks, Rusty here. Let’s get into it.
Right off the bat, we’ve got a proper run of swell heading our way into Haardebaai. This is a sheltered reef break that needs a solid W swell direction to really fire, and we’re seeing that. The water temp is sitting at 60°, which is pretty much bang on average for this time of year, so nothing weird going on there.
The first surfable option arrives Monday morning, July 20th. Haardebaai is picking up a 6ft swell from the SW with a period of 9 seconds. The combined energy is moderate at 537. It’s clean with a moderate offshore wind from the NNW. Not a standout, but a decent warm-up if you’re keen and an advanced surfer.
The standout is Tuesday morning, July 21st. This is the one. Haardebaai has a solid 10ft of SW groundswell, with a long period of 14 seconds. The energy is pumping at 3042. But the real magic is the wind: glassy, dead calm. This is going to be absolutely perfect, clean lines for experienced surfers. This is the best session on offer, no question. The only caveat is this is a reef break, and with a long-period swell, it’ll be fat and powerful, so it’s for experts only.
Wednesday morning, July 22nd, is still very good. A 8ft SW swell with a 12-second period and a gentle offshore wind from the NW. Clean and punchy. Energy is strong at 1542. Another excellent session.
Thursday, July 23rd, keeps the run going. The morning has an 8ft WSW swell with a moderate offshore wind. The afternoon goes glassy again with a 8ft SW swell. Both sessions are clean and have strong energy.
Friday, July 24th, through Saturday, July 25th, we get a big spike in size, but the wind shifts onshore and the quality drops. Not worth it for paddling.
Sunday, July 26th, we’re back in business. Both morning and afternoon have 7ft SW swells, with light offshore winds in the afternoon. Clean and lined up.
Monday, July 27th, starts off clean with a 6ft SW swell, but the afternoon gets hammered by a gale-force offshore wind at 43 mph. That’s impossible to paddle into, so skip that.
Tuesday, July 28th, the swell jumps to 13ft in the morning and 15ft in the afternoon. The afternoon session is the real deal here: 15ft, SW, 13-second period, light wind, and the energy is a massive 6207. This is huge, powerful, and only for the bravest experts. It’s a standout for the big-wave crew.
Wednesday, July 29th, is still big and clean, with an 12ft SW swell and a moderate offshore wind. Expert only.
The end of July and into August is a mixed bag of big, clean but windy conditions. The energy remains high, but the wind gets strong, making it tough to get out. The size is there, but it’s a battle.
By Sunday, August 2nd, the swell drops off hard. The 3rd and 4th of August have tiny, weak swell with strong winds. Not worth the paddle.
So, the best of the best: Tuesday morning, July 21st, for the glassy perfection, and Tuesday afternoon, July 28th, for the massive, clean groundswell. Both are for experts only.
Rusty.

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.
