The Lowdown

Righto, Rusty here. Let's have a look at what's on the cards for Bonza Bay over the next couple of weeks.

First up, the water temp is sitting at 65°, which is a bit colder than normal for this time of year – about 2° cooler than the long-term average, so you'll want a decent spring suit.

Saturday morning, the 29th of August, is the only real standout in the near term. We've got a clean 3ft SSE swell with a 12-second period and a gentle cross-offshore breeze from the NNW. The combined energy is moderate (235), and it's looking like good surf conditions. This is the pick of the early window.

Saturday afternoon stays glassy with light winds, but the swell drops to 2ft. Still surfable but nothing special.

Then we hit a rough patch. Sunday the 30th through to Monday the 7th of September is a mixed bag of poor conditions. The wind is often cross or onshore, and the swell is messy with short periods or strong winds. There's a couple of marginal windows, but nothing you'd rush out for. The energy reads moderate most of the time, but the quality just isn't there.

The next real highlight pops up on Sunday, the 6th of September, in the afternoon. The breeze turns light cross-off from the NNE, and we've got a clean 5ft S swell with a 12-second period. The combined energy is strong (739), and the forecast says expect very good surf conditions. This one comes with a bit of long-range uncertainty, but it's got promise.

After that, the forecast drops back into poor or marginal territory through to the 13th of September. The swell stays around 3ft to 6ft, but the wind is often cross or onshore, and the periods are mixed. The energy values are moderate to strong, but the conditions are just too messy for decent surf.

The final week shows a couple of marginal windows, but nothing stands out as a clear winner. The 13th of September morning has a big 8ft SSW swell with a 11-second period, but the cross-shore wind at 19 mph and lumpy conditions make it a tough one for all but the most experienced.

So overall, the best bet is Saturday morning, 29th August, for a clean, fun session. The Sunday 6th September afternoon is a promising long-range option, but keep an eye on the forecasts.

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.
