The Lowdown

Alright mates, Rusty here, giving you the straight dope on the surf.

Bonza Bay is a river mouth break, and the next couple of weeks are a mixed bag, mostly leaning towards a bummer. For the first week, from Sunday the 6th right through to Saturday the 12th, it’s basically a no-go zone. We’ve got persistent cross and cross-onshore winds, many of them fresh to strong, turning the ocean into a lumpy, choppy mess. There’s some size, like a 7ft S swell on Monday the 7th, but with 22 mph cross winds, it’s absolutely unsurfable. The wave energy that morning is off the charts, but it’s all blown out. Do yourself a favour and stay on the beach.

Your best bet lands on Sunday the 13th. We’ve got a solid 8ft easterly swell pushing in, with a period of 9-10 seconds. The wind finally lays down to a light breeze from the NE, creating a light cross-shore. The water temp is about 66°, which is pretty average for this time of year. The combined energy is well into the strong range. It’s still a marginal call with the tides, but if you can find the right bank, this Sunday morning is the one to chase. Be warned, Bonza Bay gets crowds sometimes, so be prepared for a little company.

Another one to circle on the calendar is Saturday the 19th. The afternoon goes glassy – wind is zero, a complete calm. We’re looking at a clean 4ft E swell, period 10 seconds. The energy is moderate, but with perfect, flat conditions, you could get some really smooth, clean walls. It’s a long way out, so don’t bank on it yet, but keep that date in the back of your mind.

Just a heads up for the 13th and 14th: that swell sits over 8ft, which means it’s strictly for the experienced crew. The river mouth should handle the groundswell okay, but it’ll have plenty of punch.

From Tuesday the 15th onwards, it’s back to the grind. Wind picks up again, and we’re back to cross-shore chop and poor conditions, with only a few marginal days mixed in. That glassy Saturday is the only real standout in that second week.

All in, for the beginners, the bigger days are too much. The first week is a washout. Focus on the morning of Sunday the 13th for the biggest, cleanest power, or that glassy Saturday afternoon on the 19th for a proper long-range hope. For the rest, just keep the board in the car.

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.
