The Lowdown
Alright, Rusty here. Let’s talk about what’s coming up for Bonza Bay.
Right now, the surf is pretty average. There’s a bit of swell on the way, but for the next few days, we’re gonna be dealing with a lot of onshore or cross-shore breeze and lumpy conditions. The water temp is sitting at 70°, which is a touch warmer than normal for this time of year, so that’s a nice little bonus for the skin.
The first real chance to get a clean wave doesn’t show up until Thursday morning, July 30. That’s when we get a mix of cloud cover and a light cross-offshore wind from the WSW, with the swell coming in at 6 ft from the ESE and a period of 9 seconds. The combined energy is moderate (936), so it’s not a powerhouse, but it’ll be clean. The wind is light, making for some decent lines. It’s a river mouth setup, so the long period (9 seconds) will help shape the waves up nicely. Not a standout, but a solid session if you’re keen.
Looking further ahead, the real standout is the morning of Wednesday, August 12. That’s a full two weeks out, so keep an eye on it. The forecast shows a 15 ft swell from the south with a 10-second period, glassy conditions with almost no wind, and the combined energy is massive at 4108. That’s some serious power. But – and this is a big one – that’s way too big for most folks. Only the experts should even think about paddling out. The swell direction is from the south, and the optimum for Bonza Bay is south, so the direction is spot on. The glassy wind makes it as clean as it gets, but the size is a monster. If you’re not an expert, stay on the beach.
Tuesday afternoon, August 10, also has a big 10 ft swell from the SW, but the wind is cross-onshore and it’s a bit choppy, so it’s not as clean as the 12th. The energy is huge (4064), but it’s a bit messy.
The rest of the forecast is a mix of mediocre to poor conditions. From Friday, August 1, through to Sunday, August 2, there’s a strong NE wind with lumpy cross-chop, making the surf a bit of a mess. The swell is around 6 ft to 8 ft, but the wind and chop kill the quality. For a bit, from August 3 to 5, the wind settles into a gentle cross-shore, but the swell is still cross-shore and the energy drops off, so it’s not doing much.
The second week has a few more promising windows, but the standout is definitely the 12th for the big wave crew. The 6th to the 9th sees some long-period SSW groundswell, but the wind is often cross or cross-on, and the energy is moderate. The morning of the 8th might be worth a look with a 3 ft SSW swell and a 15-second period, with a clean cross-offshore wind, but it’s small.
Overall, the best on offer is the Thursday morning, July 30, for a clean, smaller session, and the big, glassy 15 ft swell on Wednesday, August 12, for the experts. The crowds at Bonza Bay can be around sometimes, but on the 12th, the size will keep most people out.

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