The Lowdown
G’day, I’m Rusty. Let’s break down the next couple of weeks at Bonza Bay.
It’s a slow start. Early on, the waves are small and weak with the wind blowing across from the side, making things messy. The water’s sitting at 67°, which is pretty ordinary for the season.
The first real window is Wednesday morning, September 2nd. We get a SSW swell running 6ft with a 14-second period, and the combined energy is strong at 1111. Winds are cross-shore from the SW at 9 mph, leaving a little chop but this is the best looking session early on. That size is for intermediate to advanced surfers.
From Thursday the 3rd, it falls apart. Friday the 4th sees a huge 13ft SSE swell, but it’s full-on onshore with fresh winds – total blown-out mess. That ugly pattern sticks for days, with strong winds and poor conditions.
The second week is a long dry spell. From the 7th to the 15th of September, winds stay strong, often 25 mph or more from the ENE or NE, with choppy seas and nothing worth paddling for.
The only other slight chance is Wednesday morning, September 9th. Swell drops to 5ft from the E with a 10-second period and light cross-shore winds. Energy is moderate (568), but it’s still marginal.
All up, Bonza Bay isn’t offering any standout days in this 16-day window. The best bet is that Wednesday morning (September 2nd) with the SSW groundswell and lighter winds. Otherwise, give it a miss.
Stay safe out there.

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.
