The Lowdown
Alright, let's talk about Haardebaai in feet. The water is sitting at 60°, which is pretty average for this time of year, so you won't need a full winter suit.
The first few days are a total loss. Friday the 31st and Saturday the 1st are just not worth paddling out for. The waves are small, weak, and the wind is all wrong. Saturday morning has a moment of glassy conditions with some 4ft swell from the WSW, but the energy is weak. It's a skip.
Sunday the 2nd is where it starts to get interesting. The morning has a light offshore breeze from the NW, and the swell is 4ft from the SW with a 13-second period. The energy is still moderate, but it's clean and the wind is holding. It's not a standout, but it's a solid session.
The real standout of the first week is Monday the 3rd. The afternoon is absolutely glassy, with a 6ft swell from the SW and a 13-second period. The energy is nice and meaty. The wind is dead calm, the waves are clean, and it's going to be a proper session. Tuesday the 4th is also good with a morning offshore, but the swell is a bit smaller.
Now, the middle of the week gets proper but it's for experts only. Wednesday the 5th has a huge 10ft SW groundswell with a 14-second period, but the wind is howling at 22 mph. It's offshore, so it will be clean, but at that size and with that wind, it's going to be a heavy, challenging paddle. The energy is over 3000, so it's a beast. This is not for the faint of heart.
Thursday the 6th is a complete mess. The swell is up to 15ft, but the wind is onshore and strong, making it lumpy and horrible. It's a kite-surfing day, not a paddle day.
The following weekend is a bit of a mixed bag. Friday the 9th morning has a nice 7ft SSW swell with a clean offshore wind, and the energy is solid. It's a good session for experienced surfers. The rest of that week is mostly blown out or too messy.
The absolute best of the entire forecast is the second week. Saturday the 15th is a monster. The morning is glassy, with a 15ft WSW groundswell with a 15-second period. The energy is over 8000, and the wind is zero. It's glassy, it's huge, and it's a long-period groundswell, which is perfect for this reef. The afternoon is even bigger, with a 16ft swell and a 15-second period, and the energy is over 11,000. This is a once-in-a-while session, but it's strictly for experts. It's the standout, but it's a long-range call, so keep an eye on it.
The other standout is Wednesday the 12th. It's glassy in the morning, with a 13ft WSW groundswell and a 14-second period. The energy is 5089. It's another big, clean, expert-only session.
So, the pick of the run is Saturday the 15th, but it's way out there. For this week, Monday the 3rd afternoon is your best bet for a clean, fun session. If you're an expert, Wednesday the 5th morning is also worth a look, but it's going to be a battle.

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.
