The Lowdown

Alright folks, Rusty here. We’ve got a solid 16-day window of surf on the cards for J-Bay, so let’s get into it. The week kicks off with a bit of a slow start, but don’t let that fool you – there’s some serious juice lined up.

First thing, the water temp is sitting at 64°, which is about 2.3° colder than normal for this time of year. You’ll feel that chill, so don’t forget the rubber.

Tuesday 14th July is a write-off. The afternoon has a bit of 4.6ft swell from the ESE, but it’s messy with a cross-off wind and the energy is weak (414). Not worth paddling out.

Wednesday 15th July morning is a little better. Swell drops to 3.9ft from the E, still a bit weak, but a light WSW cross-off keeps things clean. The afternoon sees a bump to 5.2ft from the SW but the period drops to 8 seconds, so it’s weaker and lumpy. Nothing to get excited about.

Now, Thursday 16th July morning, we start to see the change. A solid 9.8ft from the SW, period jumping to 14 seconds – that’s proper groundswell! The energy is strong (3284) and with a light W cross-off and glassy conditions, this is for the experienced crew only. The afternoon stays solid at 8.2ft (13 seconds, 2439 energy) but the wind swings SW and clouds roll in, so it’s still good but not as clean.

Friday 17th July morning is the first real standout. 9.8ft from the SW, 12-second period, strong energy (2684) and a light W offshore wind. This is clean, powerful, and for experts only. The afternoon goes onshore with a SE wind, so the window is the morning.

Saturday 18th July is a bit of a breather. Swell drops to 3.9ft from the S, but the morning is cloudy with a light NNE cross-shore. The real gem is the afternoon: completely glassy with 3.6ft from the S and 11-second period (552 energy). It’s small, but perfect for a longboard or a fun mid-length. Very clean.

Sunday 19th July morning sees a return of size: 6.9ft from the SW, 13-second period, strong energy (1657) and a clean WSW cross-off. This is another excellent session for experienced surfers. The afternoon stays similar but with a bit more wind.

Monday 20th July is solid. 8.2ft from the SW, 11-12 second period, strong energy (1754-2034) and clean cross-off winds all day. Great for the experienced crew.

Now, Tuesday 21st July – this is the big one. The morning is exceptional: 13.1ft from the SSW, 15-second period, massive energy (7261) and glassy calm. This is a true expert-only day, and it’s a standout. The afternoon is even bigger, 16.4ft, 16-second period, 12546 energy, but it goes cross-on. Still, if you’re a charger, that morning is the session of the period.

Wednesday 22nd July stays huge. 11.5-13.1ft, 14-second period, massive energy (5523-11866). The morning is clean with a light SW cross-off; the afternoon goes cross-shore. Both are for experts only.

Thursday 23rd July is still pumping. 16.4ft in the morning, 14.8ft in the afternoon, 14-second period, huge energy (9542-6926). The wind is a moderate WSW cross-off, so it’s clean but strong. This is serious, heavy swell.

Friday 24th July the swell holds at 11.5ft, 15-second period, very long period groundswell. The energy is still huge (5944-5780). The morning has a light E cross-on, the afternoon goes onshore. This is a powerful, tricky day.

Saturday 25th July and Sunday 26th July are still solid. 9.8-11.5ft from the SW, 13-14 second period, strong energy (3417-2977). The mornings are clean with light cross-off winds. Good for experienced surfers.

Monday 27th July is another absolute standout. 16.4ft from the WSW, 13-second period, 13702 energy – that’s exceptional. The morning has a moderate offshore from the WNW, so it’s clean and powerful. The afternoon sees rain and strong SW wind, so get it in the morning. This is a big-wave day for experts only.

Tuesday 28th July is a write-off.

Information about the J-Bay Surf forecast

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

J-Bay is 19 km (12 miles) from the city of Kruisfontein. If you plan a holiday in Eastern Cape (South), look for hotels and other accommodation in Kruisfontein. Kruisfontein has rooms for a wide range of budgets as well as car hire and transport links.
