The Lowdown
Alright, Rusty here, giving you the lowdown in feet and miles per hour.
The next 16 days start off slow and choppy, but a couple of sessions will fire if you time it right.
Monday afternoon, August 3rd, we’ve got a 6-foot swell from the ESE, but the wind is cross-shore and the water is 64°F, a bit chillier than normal. The energy is moderate (849), but the surf is marginal and messy. Leave it.
Tuesday, the 4th, stays the same. A small ESE swell in the morning, light cross-wind, still marginal. The afternoon has more energy (1109) but the wind picks up to 12 mph, making it a choppy mess.
Wednesday morning, August 5th, is the first real window. The swell drops to 4 feet from the east, but the wind goes glassy – dead calm. The energy is light (392), and the waves will be small but clean. A funboard or longboard session.
From Thursday the 6th to Tuesday the 11th, it’s a long stretch of poor conditions. Onshore wind, rain, and messy swell. On the 10th, the energy jumps to 5047 with a 15-foot swell from the south, but it’s raining and blowing onshore – a total mess.
Now, Wednesday the 12th of August. This is the big one. Morning: offshore wind from the NW, and a massive 15-foot swell from the SSE with a 13-second period. The energy is enormous (14067). This is a serious, expert-only session at the river mouth. The afternoon cleans up even more with a light cross-offshore breeze and a 20-foot swell. This is the standout, but if you’re not an expert, stay on the beach.
Thursday the 13th is still big, but the wind goes cross-shore, making it lumpy.
Then, Friday morning, August 14th, gives us another gem. The swell drops to 7 feet from the south, with an 11-second period, and the wind is glassy again. The energy is moderate (1410). Clean, solid, and no wind. A great session for experienced surfers.
After that, the swell fades. By Saturday the 15th, it’s down to 2 feet, and the wind is howling at 15 mph, so it’s flat and blown out through the end.
So, the best on offer: Wednesday the 12th for the big, clean, offshore swell (expert only), and Friday morning the 14th for a solid, glassy session. The rest is small, choppy, or blown out.
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.
