The Lowdown
Right, let’s talk Yzerfontein in feet and Fahrenheit.
First surf shows up Wednesday the 12th of August. We’ve got a 6ft WSW groundswell rolling in with a 18-second period – that’s proper long-period groundswell. Water temp is 54°, which is much colder than normal for this time of year, so don’t even think about a spring suit. The wind is light offshore out of the ESE, and conditions are clean. This is excellent for experienced surfers, not for groms. The energy reading is 1965, so there’s a lot of push. The long period will work best on the reef and river sections – the beach breaks might close out.
Thursday the 13th has more size, up to 8ft, but the wind swings north at 35 mph in the morning, making it cross-offshore and bumpy. The afternoon is cross-onshore and choppy. Skip it.
Friday the 14th hangs around 6ft with a 15-second period, but the wind is messy – cross-shore in the morning, light cross-onshore in the afternoon. Nothing clean enough to get stoked on.
Saturday the 15th morning is the real gem of the first week. Swell holds at 6ft from the WSW, period still 14 seconds. Wind is light cross-offshore from the SSE at just 5 mph – that’s glassy, clean lines. Energy is still solid at 1173. This is the session to aim for.
Sunday the 16th gets up to 7ft in the afternoon, but the wind goes light onshore or cross-onshore. Not as clean, still surfable.
Monday the 17th morning is another heavy hitter. Swell jumps to 8ft, period drops to 13 seconds, wind is light cross-offshore from the south. Clean faces, but this is expert-only territory at that size. The energy is 2279.
Tuesday the 18th and Wednesday the 19th drop off – Wednesday afternoon gets thrashed by 35 mph southerly winds, total mess.
Thursday the 20th and Friday the 21st drop to 4-5ft, wind cleans up but energy is low. Not much going on.
Saturday the 22nd morning shows 5ft with a cleaner 13-second period and light offshore wind. Fun but not a stand-out.
Now, Sunday the 23rd of August is the big one for the long range. Morning has a 6ft SW groundswell with an 18-second period and glassy offshore ESE wind. Energy is massive at 3707. That’s a world-class groundswell signal, but the afternoon gets too big at 10ft – the guidance says it’s too big for this break. Monday the 24th morning is also 10ft with a 15-second period. For the chargers only.
The rest of the window fades out. Thursday the 27th morning has clean but small 5ft surf.
Top calls: Saturday the 15th morning for the best all-round clean session. For the big wave crew, Sunday the 23rd morning and Monday the 17th morning are the ones to circle – just know the water is cold and the energy is serious.

Information about the Yzerfontein Surf forecast
The above surf forecast table for Yzerfontein provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Yzerfontein can be found by selecting the local surf guide option on the grey menu. Our Yzerfontein 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 (Yzerfontein) 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 Yzerfontein 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.
Yzerfontein is 39 km (24 miles) from the city of Saldanha. If you plan a holiday in West Coast, look for hotels and other accommodation in Saldanha. Saldanha has rooms for a wide range of budgets as well as car hire and transport links.
