The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s on the cards for Corner.

First up, the next few days are pretty quiet. Monday the 17th only has tiny 1-foot to 2-foot cross-off swell with very weak energy. Not much to write home about. Tuesday the 18th isn't much bigger but the energy jumps up a notch, especially Tuesday afternoon with 3-foot swell from the SW and moderate energy. Conditions are clean, so you could get a few fun ones if you’re desperate.

Now, Wednesday the 19th is a tale of two halves. The morning is blown out with cross-on wind and messy surf. But Wednesday afternoon? That turns glassy. The swell holds at 4 feet from the SSW with moderate energy and the wind is dead calm. That’s your first real standout – clean, glassy conditions on a reef break that’s consistent. It’ll be crowded, no doubt, but for a Wednesday arvo session, it’s about as good as it gets right now.

Thursday the 20th sees the swell building. Morning is 6 feet from the SW with a short period of 8 seconds and moderate energy, but clean with cross-off wind. Afternoon jumps to 7 feet from the SSW with a longer 14-second period and very strong energy. That’s a solid groundswell, but it’s getting big. For most punters, 7 feet at a reef break is getting into expert territory. Only the experienced crew should paddle out.

Friday the 21st is a write-off – strong cross-onshore wind and poor conditions all day. Saturday the 22nd is worse, with 19 mph wind in the arvo making a mess of things.

Now, if you’re looking ahead, keep an eye on Sunday the 23rd. The morning has a whopping 15-foot swell from the SSW with a 14-second period and extreme energy. That is massive, dangerous, and only for the absolute top-end experts. Afternoon drops to 10 feet from the south with similar energy. If you’re not charging, stay on the beach.

Monday the 24th keeps the big 10-foot south swell going, but onshore wind makes it ugly. That continues into Tuesday and Wednesday the 26th with lumpy, blown-out conditions.

We finally get a breather on Thursday the 27th morning. Swell drops to 3 feet from the SSW, 14-second period, light cross-off wind, and clean with moderate energy. Comfortable, surfable waves for the intermediate crew. Friday the 28th morning is glassy again with 3-foot SSW swell and light energy – small but clean.

The end of the window, around Sunday the 30th, throws up 7-foot SSW swell but with 22 mph wind. That’s just ugly.

So, the pick of the fortnight? Wednesday afternoon the 19th for a glassy, clean 4-foot session, or Thursday the 20th afternoon for the more experienced looking for a bigger, long-period groundswell. Keep an eye on Sunday the 23rd if you’re a big-wave charger, but that’s a whole different ballgame.

Rusty.

Information about the Corner Surf forecast

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

Corner is 7 km (4 miles) from the city of East London. If you plan a holiday in Eastern Cape - Wild Coast, look for hotels and other accommodation in East London. East London has rooms for a wide range of budgets as well as car hire and transport links.
