Alright, Rusty here, let’s take a look at what Bonza Bay has cookin’ for us over the next couple of weeks.

Right off the bat, Sunday morning, July 5th, is the start of the action. We’ve got a solid 5ft SE swell rolling in with a nice 12-second period, and the wind is a light 3 mph NE cross-offshore. That’s about as clean as it gets, so the waves will be lined up and peeling real nice. The water is sitting at 64°, which is 5° colder than normal for this time of year, so you’ll want a decent wetsuit. The combined energy is a moderate 634, so it’s not a monster but there’s enough push for a fun session. This is your standout session – get out there early. The afternoon takes a step back with a 9 mph ENE cross wind and only 4ft on offer; it’s still surfable but not worth rushing.

Monday, July 6th, drops off a bit. The morning is a 3ft SE swell with a 10-second period, but the 6 mph S cross-on wind puts a bit of a ripple on the face. The afternoon goes glassy with a 3 mph ENE breeze, making for a clean but small 3ft wave. It’s a knee-to-waist-high day, okay for a longboard but nothing to get fired up about.

Tuesday, July 7th, through to Wednesday, July 8th, is a write-off. We’ve got 2ft to 3ft SSW swell but cross winds from the south-west at 12 to 22 mph. The wave quality is poor, and the energy is weak to moderate (222 to 266). Not worth paddling out.

Thursday, July 9th, morning sees a big jump to 10ft SSW swell with a 12-second period and a clean WSW cross-off breeze at 12 mph. The combined energy is strong at 3925, but this is too big for Bonza Bay – only for experts if they can handle a washing machine. The afternoon drops to 8ft but the cross wind chops it up.

Friday, July 10th, stays big with 8ft to 8ft S swell, but the wind is either cross or cross-on, and all sessions are marginal. This is big and messy – not recommended for paddle surfing. Saturday, July 11th, drops to 5ft to 6ft S swell but the wind is cranking at 19 mph cross, so it’s lumpy and poor.

After that, there’s a long stretch of mediocre conditions from Sunday, July 12th, through to Friday, July 17th. Waves between 3ft and 5ft, mostly from the S or ESE, but the wind is all over the place – cross, cross-off, and often over 9 mph. The energy is weak to moderate (183 to 451). Wednesday morning, July 15th, gets a mention with a glassy 0 wind and 4ft E swell at a short 9-second period. It’ll be clean but a bit weak and fat.

Then, Saturday, July 18th, we get a massive spike: 16ft SSW swell with a 14-second period and a combined energy reading of 15008. That’s proper big. The morning has a 9 mph SW wind, and the afternoon switches to a light 6 mph SE onshore. This swell is way too big for Bonza Bay – it’s a dangerous, thumping wall of water for experts only, and even then, it’s pushing the limits. Sunday, July 19th, drops to 12ft to 10ft, still huge, with cross winds and lumpy conditions.

From Monday, July 20th, onwards, it fades back to 5ft to 6ft S swell with fresh cross winds – poor surf, not worth a look.

The standout session is Sunday morning, July 5th – 5ft SE, offshore wind, clean lines. That’s your best bet. After that, there’s a long gap of onshore and blown-out conditions until Saturday, July 18th, but that’s only for the brave and the stupid. For everyone else, pick your window carefully.

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.
