The Lowdown

G’day, I’m Rusty. Let’s take a look at what Bonza Bay is doing over the next couple of weeks in feet and miles.

The surf window opens up Wednesday morning, 2nd September. We’ve got a south-southwest swell running about 5 feet with a 14-second period – that’s a decent groundswell with solid energy (combined energy of 975). The water temp is around 66°, pretty normal for this time of year. The wind is light and cross-on from the SSW, so it’ll be a bit choppy, but it’s rideable for intermediate surfers. It’s a river mouth, so those longer 14-second intervals might not peel as nicely as at a reef, but it’s worth a paddle. Crowds can pop up sometimes, so keep your wits about you.

Wednesday afternoon goes downhill fast – east wind picking up to 12 mph and conditions turn ugly. I’d bail after the morning session.

Thursday 3rd September the swell drops to 3 feet from the south with an 11-second period. The wind is cross-shore from the SW, and there’s some chop. Not worth suiting up.

Friday 4th September brings a bigger bump: 8 feet from the SE with a short 9-second period (energy jumps to 1598). The wind is onshore from the SSE at 16 mph, so it’s a mess. That’s getting big for beginners, and with that wind, it’s a washing machine.

Saturday 5th September morning has 5 feet from the ESE with a short 8-second period and a cross-shore wind from the ENE. It’s marginal – not terrible, but not clean. The afternoon drops to 4 feet from the south, but the wind stays cross-shore and lumpy.

Sunday 6th September morning is tiny – 2 feet from the SSW, but with a very long 24-second period. That’s a groundswell with heaps of energy (720), but it’s waist high and the wind is cross-shore. The afternoon gets bigger to 5 feet from the SSW with a 21-second period (energy up to 1838), but the wind is fresh and cross-shore. There’s a chance for a rare clean wave at the river mouth if the tide plays ball, but it’s a long shot.

Monday 7th September morning has 4 feet from the SSW with a 15-second period (energy 1048) and clear skies, but the wind is cross-shore. The afternoon jumps to 7 feet from the east with a short 8-second period – that’s getting too big for intermediates, and with a fresh cross-shore wind, it’s lumpy.

The rest of the week into the second week is mostly small or poor. There’s a big pulse on Monday 14th September: 10 feet from the SSW with a 12-second period (energy 3024). That’s a beast – experts only. But the wind is cross-shore from the ENE at 22 mph, so it’s going to be total chaos. That setup looks more interesting for kite surfing than paddle surfing.

Thursday 17th September morning has 5 feet from the SSW with a 16-second period (energy 1647), but the wind is cross-shore at 16 mph. Marginal.

The standout is Wednesday morning 2nd September – not perfect, but the most surfable slot with that 5-foot groundswell and light wind. After that, it’s mostly chop and wind. The second week is a coin flip – keep an eye on it, but don’t plan a trip around it.

Stay salty,
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.
