The Lowdown

Alright, this is Rusty, checking in from the local stretch. The next couple of weeks are a bit of a mixed bag, but there are some windows for sure.

The overall pattern kicks off with a decent start, then it gets a bit messy through the middle before we see some cleaner conditions returning towards the end of the first week and into the second.

Saturday morning (29th August) is a solid pick. Bonza Bay is a river mouth, and it’s picking up a clean 3ft groundswell from the SSE with a nice 12-second period. The wind is a light northerly, which is a cross-offshore breeze, so the surface will be clean. The combined energy is moderate (235), and it’s got enough shape to be fun. Crowds are sometimes an issue here, but it should be well worth it for a morning session.

Saturday afternoon the swell jumps to 6ft from the east, but the wind swings to a westerly cross-off, keeping it clean. The energy rises to 828, so it’ll have a bit more punch. That’s a solid afternoon.

Sunday morning (30th August) is a wipeout. The wind picks up to 12 mph from the WSW, the swell drops to 4ft, and the period collapses to a short, weak 6 seconds. The energy is only 118. The conditions are poor, so give it a miss.

Monday through Wednesday is a run of marginal to poor conditions. The wind is mostly cross-onshore, and the swell is inconsistent. On Wednesday morning (2nd September) there’s a pulse of 4ft swell from the SSW with a 13-second period and a big energy reading of 867, but the onshore breeze makes it choppy. Not the best.

Thursday morning (3rd September) is back on. A clean 6ft swell from the SSE, light cross-offshore wind from the WSW, and the energy is 354. That’s a solid, clean option for a morning session. The afternoon, however, gets hammered by 28 mph onshore winds, so it’s a no-go.

Friday (4th September) sees the swell get bigger. The morning has 7ft from the SSE with an 8-second period, but the wind is onshore, making it a mess. The afternoon has a 7ft swell from the south with a very long 16-second period, giving a massive 2440 energy reading. That’s a powerful, long-period groundswell, but the wind is cross-onshore, so it’ll be choppy. This is one for experienced surfers only, and it’s better suited to the point or reef setups than a beach break. A bit of a caveat.

Saturday (5th September) is a write-off with strong winds.

Sunday afternoon (6th September) is a nice surprise. The swell drops to 3ft from the SSW, but the period is a long 14 seconds, and the wind goes glassy. The energy is 441. That’s a clean, small groundswell for a longboard or a fun afternoon session.

After that, the forecast gets pretty grim. From Monday the 7th through to the end of the forecast period, the conditions are mostly poor with choppy winds and small, weak swells. There’s a slight chance of a clean-up on Sunday morning (13th September) with a 4ft swell from the SSW and a long 14-second period, but it’s a week and a half away, so we’ll have to see how it pans out.

The water temperature is about average for this time of year.

So, the standout is Saturday morning (29th August) at Bonza Bay. The best of the rest is Thursday morning (3rd September) .

Stay stoked, and I’ll catch you in the water.

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.
