Right then, grab a coffee, this is a juicy one. We’ve got a proper run of surf on the cards, but you gotta pick your moments. The water’s sittin’ at 63°F, which is a bit colder than we usually expect for this time of year – about 3°F off, so you’ll want that extra-thick wetsuit.
The real show starts Sunday afternoon, the 5th of July. That’s the opener. It’s small, only 4ft from the ESE, but with 5 km/h WSW glassy winds, it’s gonna be a dream. This is a classic "quality over quantity" session – clean, easy, and perfect for getting the rust off. The energy’s moderate (901), so it won’t be a grunt, just smooth. This is your warm-up.
Then, Monday morning, the 6th, is where it gets serious. The swell jumps to 6ft from the SW, a proper 12-second groundswell, and the wind is a magical 5 km/h NW and glassy. The energy is up (1059). This is a standout. For the experienced crew, this is pure gold. Don’t be late.
Now, it gets a bit hairy from Monday afternoon through Tuesday. The swell builds, hitting 7ft on Tuesday morning, but the wind swings onshore and cross, making things messy. The energy is strong (1336 on Tuesday morning), but the quality drops. The sets will be there, but the surface will be a mess. It’s a big, bumpy wall.
The real power arrives Thursday and Friday, the 9th and 10th. Thursday morning has 12ft of SW swell at 14 seconds – that’s a massive, powerful groundswell. The energy is very strong (4153). But the wind is a 25 km/h cross-off. It’s gonna be big, clean lines for the experienced crew, but 12ft is expert territory. Friday morning has the same size, 12ft from the SSW, but with a glassy 5 km/h E wind! That’s the peak of the swell with perfect conditions. The energy is massive (5015). If you have the skills, this is *the* session for the whole run. It’s a proper, heavy, clean J-Bay. Friday afternoon goes to hell with a 25 km/h cross-on breeze, so get your waves early.
We get a reprieve Saturday afternoon, the 11th. The swell drops to 7ft from the SSW, but the wind goes glassy again (5 km/h SSE). The energy is still strong (1883). This is a beautiful, clean window for intermediates who found Friday too heavy.
Sunday morning, the 12th, has a weird one: 8ft from the SE with an 8-second period. That’s a short-period, wind-driven swell. It’s glassy though, and the energy is moderate (1220). It could be fun and punchy on the inside, but it won't have the push of the groundswell.
After that, we hit a lull. From the 13th to the 15th, the swell drops and the wind is mostly howling from the WSW, cross-off. The waves get small and blown out. By Wednesday the 15th, it’s down to 2ft with 25 km/h winds. There’s a few days here where it’s not worth paddling out. A bit of a dead spot for a few days.
But hold on. Saturday morning, the 18th of July, we get a new pulse. It’s 5ft from the SSW with a very long, 15-second period. Wind is clean, cross-off from the WSW at 10 km/h. The energy is strong (1420). This is a classic, lined-up, long-period J-Bay swell. Perfect for the point. It’s one of the best of the second week.
Sunday the 19th is also a looker – 8ft from the WSW at 13 seconds, cross wind from the NE. That’s a big, solid swell for experts. The energy is very strong (2701). It’s a standout for those who want size.
So, to sum it up: the absolute best is Friday morning, the 10th of July. Big, heavy, clean, and firing. Second best is Saturday morning, the 18th of July, with that long-period groundswell in perfect conditions. The crowd at J-Bay is "sometimes" an issue, so for those standout windows, expect a few mates in the water.
Stay safe, pick your days, and don't be a hero when it’s ugly.

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.
