Table - best surf conditions forecast for Bonza Bay over the next 16 days.
Alright, let’s talk Bonza Bay. This is the only game in town for the next 16 days, and it’s a bit of a rollercoaster. Water temp is about normal for the season.
Saturday the 11th starts with a 7ft south swell, 13-second period – good groundswell. Wind is light cross-onshore, so the lines will be lumpy. Energy is strong at 1425, but the quality is just marginal.
Sunday the 12th drops to 5ft and wind picks up. By afternoon it’s choppy and poor. Skip it.
Monday the 13th gives you a 6ft east swell but only 7 seconds – that’s short-period junk. Not worth it.
Here’s your first window: Tuesday the 14th morning. Glassy conditions, SW wind at 3 mph, and a 6ft ESE swell at 8 seconds. It’s small but clean as glass. Energy moderate at 499. Crowds possible, so get out early.
From Wednesday 15th through Friday 17th, it’s a write-off. Strong cross-winds and poor surf.
Second week brings size. Saturday 18th and Sunday 19th have 7ft to 8ft south swells with 13-second periods, but winds are 15-19 mph cross-shore. That’s big, lumpy, and for experts only.
Then look at Thursday the 24th afternoon. A 6ft SSW swell with a 22-second period – that’s an incredibly long groundswell. Energy is extreme at 4123. Light wind, clean. Long period swells like that work best at Bonza Bay because it’s a river mouth. Mark it, but it’s over a week away.
The true standout is Saturday the 25th morning. Glassy, no wind, 6ft SSW swell with a 17-second period, and excellent conditions for experienced surfers. Energy strong at 1948. That’s your best session in the whole 16 days. Get on it.
So, Tuesday 14th morning for clean small waves, and Saturday 25th morning for the big, clean, powerful session. Crowds likely.
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.
