The Lowdown

Alright folks, Rusty here. Let’s have a look at what’s cookin’ for Bonza Bay over the next couple of weeks.

First off, I gotta be straight with you – the start of this forecast is a tough one. We’ve got a solid groundswell arriving on Monday afternoon, with a 6ft south swell packing a serious punch of energy (1281). But that ENE wind is howling at 25 mph, ripping straight across the line. It’s a mess out there, with messy cross-chop. No good for a paddle. The water temp is sitting at 66°, which is about average for this time of year, so nothing weird going on there.

We’ve got a long stretch of poor conditions through the week. Tuesday drops to a smaller 3ft, but it’s cross-onshore and choppy. Wednesday and Thursday are tiny and weak. Honestly, if you’re looking at this for a surf, you’re better off waiting.

The first real glimmer of hope doesn’t show up until Saturday afternoon, the 12th. We see a 5ft east swell, moderate energy (596), and cross-shore winds. It’s still a bit lumpy, but it’s a step up from the junk we’ve been lookin’ at. The real standout, though, is Sunday morning, the 13th. That’s where it gets interesting. A 4ft SSW groundswell, but with a very long period of 16 seconds and a massive 876 energy reading. The wind is a light cross-shore breeze – just small ripples on the water. That’s as clean as it gets. This is a proper groundswell, so it’ll bend and wrap nicely into the river mouth at Bonza Bay. It’s a bit on the smaller side, but the quality and shape will be there for a patient surfer. Just a heads up, it can get a little crowded here sometimes.

After that, it’s a bit of a mixed bag. We get a south swell on the 15th with a 6ft east swell, but the wind is onshore. Then we get another big spike on the 17th and 18th – 7ft and 7ft south swells, but with strong cross-shore winds and rain. That’s a lot of water moving, but it’s gonna be a lumpy, messy beast. Not beginner-friendly.

The second week starts to look a little more promising. Saturday the 19th has a 5ft SE swell with a clean cross-offshore wind – that’s the best wind direction for this spot. Sunday the 20th is the best bet in the long range. We’re looking at a 8ft east swell, strong energy (1126), and light cross-shore winds. It’s a touch big for beginners, but for the experienced crew, that’s a fun, solid day. The forecast is a bit less certain this far out, so keep an eye on it.

So, to sum it up: the first week is a write-off. Sunday morning, the 13th, is your best bet for clean, quality waves on the smaller side. Then Sunday the 20th is the big one to watch for a punchy, powerful session if you’ve got the skills.

Rusty, signing off.

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.
