The Lowdown

Alright, Rusty here. Let’s talk about what’s cookin’ at Bonza Bay.

Right off the bat, the next few days are a bit of a write-off, if I’m being honest. The forecast starts with some S swell but the wind’s swinging cross and the conditions are just messy. That Tuesday, August 25th, has a clean 3.6ft S swell in the morning but the wind is making it lumpy – it’s not worth paddling out for. Wednesday the 26th gets a bigger 8.2ft S swell but it’s too onshore and choppy, especially in the afternoon.

We get a nice little window on Friday morning, August 28th. The wind drops to glassy, and there’s a 5.6ft E swell rolling in. The combined wave energy is moderate (1047), and it’s a good size for an intermediate surfer. That morning window is your best bet in the first week – clean, fun, and manageable.

Saturday morning the 29th sees a 5.6ft E swell with clean cross-off winds, but it’s not quite as glassy. Still worth a look, though.

Then things get weird. From Saturday afternoon through the end of August, the surf drops off and the wind turns messy again – small waves, onshore flow, just nothing to get excited about.

Now, come September, we’re lookin’ at a whole different beast. The first real standout is Friday, September 4th. A 9.8ft SSE swell is predicted with light winds and favorable conditions. But mate, at 9.8ft, this is expert territory – it’s gonna be a big, powerful wave at Bonza Bay. The combined energy is strong (3241). This is not for the faint of heart.

Then Saturday, September 5th, we get a massive 23ft SE groundswell (12,902 combined energy). That’s a heavy-duty, very long-period groundswell. Again, the conditions are favorable, but this is huge. Only the most experienced locals should even think about it. The same goes for Sunday the 6th, with 14.8ft ESE swell and fresh cross-shore wind making it lumpy.

There’s a window on Monday, September 7th, with an 11.5ft E swell and lighter winds, but again, that’s a big, solid swell. The second week is all about these big, powerful, expert-only waves. If you’re not an advanced surfer, you’re better off waiting.

So, bottom line: Friday morning, August 28th, is the clear winner for clean, fun surf. If you’re an expert, circle September 4th and 5th for some serious, big-wave action – but those are for the crew with the biggest set of lungs and the most experience.

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.
