The Lowdown

Alright, Rusty here. Let’s talk about what’s cooking for this stretch of coast.

Right now, things are pretty flat and ugly, so we’re looking at a gap of about 5 days with no real surf to get excited about. The first chance of something rideable shows up around Friday the 14th, so hold tight.

Friday 14th August is where it starts to turn. Haardebaai is a reef setup that takes a southwest groundswell, and early morning we’ve got a clean 6 ft swell from the WSW, period a solid 15 seconds, and the wind is dead glassy. That’s about as clean as it gets for this spot. The water temp is sitting about average for the time of year. The combined swell energy is in the moderate-to-strong range (1369), so there’s some push behind it. This is a standout window – light crowds possible, but the conditions will be prime.

Saturday 15th August keeps the good vibes rolling. Morning brings a moderate offshore breeze from the NW with that same 6 ft WSW swell and 14-second period. It’ll be clean and lined up. Afternoon sees a lighter cross-offshore, still very surfable. Consistency is good here – this reef handles the southwest direction nicely.

Sunday 16th August morning is another highlight. Offshore NW winds around 15 mph, 6 ft swell from the WSW, 15-second period, combined energy at 1505. That’s solid, clean, and punchy. The afternoon gets a bit more size at 7 ft but the wind swings cross-off, so it stays manageable for the advanced crew.

Monday 17th August turns ugly again. Strong cross-onshore winds from the ESE and a big 10 ft swell from the WSW, but it’s blown out and lumpy. Not worth it.

Tuesday 18th August morning brings a surprise – glassy conditions again, 7 ft swell from the WSW with 12-second period. Clean waves, but the energy has dropped to moderate (1142). Still a good session for those who can get out.

After that, things fade and get messy through to Friday 21st August, when a bigger pulse arrives. Friday afternoon sees a 10 ft WSW swell with 12 seconds, light cross-offshore winds, and combined energy jumping to 3284. That’s strong, but it’s big – only for experienced surfers. Promising, but it’s over a week away, so keep an eye on it.

Saturday 22nd August morning looks like the real standout of the second week. Light offshore breeze from the NNW, 8 ft swell from the SW, 12-second period, combined energy at 1801. Clean and powerful, with lighter crowds. That’s the one to pencil in.

Sunday 23rd August afternoon gets huge – 12 ft from the SSW with 16-second period, but onshore wind and very high energy (5736). That’s expert-only and probably blown out.

Monday 24th August onwards sees the swell drop but the wind stays onshore, so it’s mostly a washout until Tuesday 25th August morning, when a light offshore breeze and a small 4 ft clean swell show up. Not much power, but glassy and rideable.

Overall, the best bet is Friday 14th August morning at Haardebai – glassy, solid 6 ft groundswell, and clean. Saturday 22nd August morning is the long-range standout, but it’s a week and a half out, so don’t lock it in yet.

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.
