The Lowdown

Alright, mates, Rusty here. Let’s have a proper look at what the ocean’s got cookin’ for Bonza Bay over the next couple of weeks. It’s a bit of a mixed bag, so let’s break it down.

The early part of this stretch is looking pretty average, to be honest. There’s some swell around, but the winds are all over the shop, and the surf quality is suffering for it. We’ve got a bit of a wait on our hands before things start to clean up and show some real potential. The first real standout doesn't arrive until the 2nd of September, so we're looking at a few days of marginal, onshore slop before then.

The trouble starts right away on Friday the 28th of August. There’s a 5.6ft easterly swell at 10 seconds, but a NE cross-breeze is putting a bit of chop on it. The water temp is 66.7°F, which is about normal for this time of year. The combined energy is moderate at 943, but the overall vibe is just messy. Saturday morning the 29th looks better—the wind swings to a light N cross-offshore, and the swell is still 5.6ft from the east. That’s clean and rideable, but then it all falls apart after lunch as the wind turns SW and the swell drops right off to 2.3ft. The rest of the weekend and Monday look poor—small, short-period lumps with cross-shore winds, not worth getting excited about.

We’ve got a dry spell for a few days until a bigger pulse shows up. Wednesday the 2nd of September is where things get interesting. The data shows a big jump in energy, with a 6.9ft SSW groundswell hitting with a 17 second period. That’s proper, long-period groundswell energy, with a combined energy reading of 2503. The problem is the wind is a gentle cross-onshore, so it’s likely to be a bit lumpy. It’s a river break, and this long-period swell might be breaking a little straight, but there’s power in the water. This is the first one worth making a plan for.

Following that, the 3rd of September Thursday looks like a write-off. It jumps up to 13.1ft, but with a strong 45 km/h (28 mph) SSE cross-onshore wind and rain, that’s going to be a washing machine. That is well into expert-only territory and honestly, it's going to be a mess. The setup looks more interesting for kite surfing than paddle surfing on that day.

After that stormy blip, the surf settles back down but the winds stay fresh and onshore for a long stretch. From the 4th through the 9th of September, we’ve got swell, but it’s constantly chopped up by fresh E/NE winds. There are some bigger pulses in there, but they’re all wind-affected. It’s a long few days of poor-to-marginal conditions. The highlight of this period is a clean window on the 11th of September. Friday morning shows a 6.2ft ESE swell and the wind is a gentle SSH cross. It’ll be a bit raw, but it could be a session worth having if you’ve got the itch.

The final standout is on Saturday the 12th of September. This is the one to circle on the calendar. We get a solid 7.9ft easterly swell with an 11-second period, generating strong wave energy at 2391. The morning wind is only a light ESE cross-onshore, which could be glassy early. This is the biggest, cleanest, most powerful swell of the whole period. It’s a lot of water, so probably for the more experienced crew, but it's the best on offer. The afternoon wind picks up but the morning session looks magic.

So, in summary: the next week is mostly a write-off with a few short windows. The real gems are the 2nd and especially the 12th of September. The 12th is the standout, looking like the cleanest and most powerful day of the stretch. But remember, it’s far out, so keep an eye on the charts.

Stay stoked.

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.
