The Lowdown
Alright, Rusty here, with the forecast for Keurbooms in the units you asked for.
First thing, the water is damn cold, sitting at 57°, which is a massive 6° colder than normal. That’s a serious anomaly, so layer up.
The start on Friday the 11th is flat and messy. There’s a 5ft swell from the SW, but it’s onshore and choppy. Wave energy is moderate (879), not worth the hassle.
The first real window is Saturday morning, the 12th. It’s small at 3ft from the SW, but it’s glassy and clean, with a long 15-second period. A perfect day for a log or a fun board. Energy is moderate (470).
The absolute standout is Saturday afternoon, the 12th. Swell jumps to a clean 7ft from the SSW with a 14-second period. It’s glassy, clean, and the energy is strong (1827). This is the one to circle for experienced surfers. It’s a proper session but too big for beginners.
Sunday the 13th is a write-off. Strong ESE wind and a massive 10ft afternoon swell makes it an expert-only, blown-out mess.
Monday the 14th morning goes glassy again with a 8ft ESE swell, but tides are tricky. Good for experienced crew only.
Wednesday the 16th morning brings a solid 10ft SW groundswell, clean wind, but it’s way too big for the break. Experts only, and the energy is very strong (4429).
From Thursday the 17th through the 25th, it’s a long stretch of onshore wind, blown-out conditions, or marginal surf. Not much to get excited about.
We finally get a nice clean morning on Saturday the 26th. It’s 5ft from the SW, glassy, with moderate energy (774). A solid session to finish on, if you’re patient.
The pick of the whole forecast is Saturday afternoon the 12th. After that, it’s a long wait before the 26th. Keep your expectations low for the second week.
Rusty.

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