The Lowdown

Alright, Rusty here. Let's have a look at what Bonza Bay is serving up over the next couple of weeks.

Right off the bat, the water at Bonza Bay is running a bit colder than normal for this time of year, sitting at 64°F with a negative anomaly. So you'll want a decent wetsuit.

To be honest, the first real window of opportunity is brief and not exactly firing. This Tuesday morning, we’ve got a modest 6ft swell from the east, with an 11-second period. The combined swell energy is sitting at (858), so there’s some moderate power behind it. The wind is a light cross-onshore from the SSW, which will keep things a little bumpy. It’s a marginal call for the morning, and the afternoon drops off a bit. Wednesday through Friday is a write-off with poor conditions and lumpy, choppy seas, especially Friday when the swell pumps up to 8ft to 10ft, but those easterly winds will have it all messy.

Honestly, the one true standout that might be worth a look is on Saturday the 19th of September. The swell hangs in at a solid 10ft from the ESE with a period bumping up to 10 seconds (combined energy of 1986, which is strong). Now, the wind is a gentler cross-onshore and the forecast actually calls for favourable wind and tide. The catch? That size is getting into expert territory, over 8ft, so this is strictly for the experienced crew. Crowds are possible here, so don't expect to have it to yourself.

After that, Sunday the 20th afternoon offers a brief bit of hope with a 6ft east swell and a clean, cross-off wind from the WSW, but the conditions are still described as marginal. From there, it’s a long, grim stretch. The following week (from the 22nd of September right through to the 30th) is mostly plagued by poor conditions, strong onshore winds, or just weak, small swells. Monday the 29th sees a 8ft swell from the SW, but it’s going to be a lumpy cross-shore mess with a fresh breeze.

To wrap it up, for the next two weeks, the only true highlight for the big-wave chargers is that Saturday the 19th. Everything else is either too small, too windy, or too messy to get excited about.

Rusty.

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.
