The Lowdown

Alright folks, Rusty here. Let’s get into it. The only spot on the radar for this stretch is Haardebaai, a sheltered reef setup that favours a west swell direction. The water temp is about average for the time of year, so nothing weird there — just your standard winter suit conditions.

The window starts off with a bit of a tease. Saturday morning, the 15th, is looking clean with a glassy 6 ft swell from the WSW, 13-second period, and moderate energy (1093). It’s the best of the first few days — light winds, decent shape, and it’s a reef, so that long-period groundswell should line up nicely. Not huge, but very surfable.

Then things get messy. Saturday afternoon through Sunday, the wind swings onshore and the swell jumps up, but the quality drops. Sunday morning has offshore wind from the NW at 30 km/h, but the forecast is marginal — the swell is a bit raw and bumpy. Sunday afternoon, same deal: 8 ft and offshore, but still not clean enough to call it good.

Monday the 17th morning is a standout for the experienced crew. A solid 10 ft WSW swell, 13-second period, and gentle offshore wind from the NNW. The energy is strong (2586), and the conditions are clean. This is proper, but it’s big — over 8 ft — so only for those with some time in the water. Monday afternoon gets cross-shore and loses its shine.

From Tuesday the 18th through Thursday the 20th, it’s pretty grim. Onshore winds, choppy, lumpy, and a string of poor surf conditions. The swell stays around 7–10 ft, but the wind wrecks it. Not worth paddling out.

Then Friday the 21st brings a nice rebound. Glassy conditions in the morning with a 7 ft WSW swell and 11-second period — moderate energy (1418) but clean. Friday afternoon gets even better: 8 ft, 14-second groundswell, light cross-offshore wind, and energy jumping to 3049. This is a solid session, though the size and power mean it’s still for the experienced surfer.

Saturday the 22nd is a write-off. Near gale-force winds, 13 ft swell, and though it’s clean, the wind is howling at 60 km/h. That’s kite territory, not paddle surfing. Energy is huge (5064–5883), but no one’s having fun on a surfboard.

Sunday the 23rd and Monday the 24th are messy again — cross-onshore, choppy, dropping swell. Monday afternoon drops to 4 ft and 796 energy, so flat and weak.

But then Tuesday the 25th morning looks promising again. A long-period 17-second SW groundswell at 8 ft, with light cross-onshore breeze. Energy is high (3674), but that long period will make it pitchy — best for the reef setup. Wednesday the 26th is the real gem: offshore NW wind, clean, 8 ft SW swell, 14-second period, and excellent conditions. That morning is a standout — keep it marked.

The rest of the week into the 30th fades back into onshore wind and choppy, marginal surf. A few flashes of clean conditions on the 27th, but the wind is moderate and the swell is backing off.

Bottom line: Saturday the 15th morning, Monday the 17th morning, Friday the 21st, and Wednesday the 26th morning are your best windows. The 26th is the pick of the bunch — clean, offshore, solid groundswell, and a reef that can handle it.

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.
