Alright, Rusty here. Let’s have a look at what the ocean’s got cookin’ for the next couple of weeks.

We’re looking at Bonza Bay for this whole run, and honestly, it’s a bit of a mixed bag. The water’s sitting at 65°, which is 4° colder than normal for this time of year – that’s a notable chill, so you’ll want a decent steamer.

The good stuff kicks off Sunday morning, July 5th. We’ve got a clean 5 ft SE swell rolling in with a 12-second period and a light 6 mph NNE cross-offshore breeze. The energy’s moderate at 634, and it’s setting up for some really nice conditions.

Monday the 6th is a drop-off. The swell fades to 3 ft, but Monday afternoon goes glassy with a 3 ft SE swell and 10-second period. It’s surfable but very ordinary – a paddle-out for a mellow session.

Tuesday the 7th is small, with a 2 ft SSW groundswell with a long 14-second period on the morning. That period is nice, but the size is tiny. The combined swell energy is weak at 182. It’s clean thanks to a light WSW breeze.

Things start to stir again on Wednesday the 8th. The swell builds through the day, hitting 5 ft by the afternoon, but it’s accompanied by a stiff 19 mph SW cross-breeze creating lumpy, choppy conditions. The energy is moderate at 679, but the wind wrecks it.

Now, here’s the first standout. Thursday morning, July 9th, has a solid 7 ft S swell with a 13-second period, clean conditions under a 12 mph SW cross-offshore wind, and strong energy at 1666. The size is pushing into the intermediate-to-expert territory, and with clean conditions, it’s got some punch.

The real gem, though, is Friday morning, July 10th. Absolutely glassy conditions, an 8 ft S groundswell with a long 14-second period, and massive energy at 2367. This is excellent surf for experienced surfers. The wave shape will be solid, with good power. Just be aware, the swell direction is S, which is a good match for the optimum direction here.

Saturday the 11th gets messy with a strong ENE breeze and risk of thunderstorms. The swell stays around 6 ft but the conditions are poor.

Sunday the 12th morning is a nice little surprise – glassy again, with a 4 ft S swell and 568 energy. Clean lines, good for a fun session.

The second week settles into a pattern of moderate to fresh WSW winds, with periods of clean cross-offshore flow. The swell fluctuates between 4 ft and 7 ft, with energy ranging from moderate to strong. Wednesday morning July 15th is worth a mention – glassy conditions and a clean 4 ft E swell, but it’s small.

The very end of the forecast, Saturday morning July 18th, shows a big 10 ft S swell with a 9-second period and moderate energy at 2640. But the file says it’s predicted to be too big for this break. The period is short, so it will be a lot of churn. That one’s for the wide-eyed experts or maybe the kite crew.

Overall, the best wave of the run is Friday morning July 10th. That glassy, 8 ft S groundswell with the long period is a proper session for those who can handle it. The other clear winner is Sunday morning July 5th for a cleaner, more approachable chest-high wave.

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.
