Alright, Rusty here, giving you the lowdown on Bonza Bay (river) for the next couple of weeks.

Right now, the surf is so-so. We got a 2.2m E swell on Monday morning, but the wind is cross-shore from the ENE at 15 km/h, and there’s a bit of chop. The combined energy is strong (1109), but the period is short at 8 seconds, so the waves are a bit gutless. Monday afternoon gets smaller.

Tuesday morning, the 14th, is the real gem. The swell drops to 1.9m from the E, but the wind is glassy – dead calm, zero wind. The water temp is 64°, which is about 4° colder than usual for this time of year, so that’s a real chill. The waves will have a bit more shape with a 9-second period, and the energy is still solid (685). It’s gonna be clean, smooth, and really fun for an intermediate. That’s your best bet.

Wednesday morning the 15th is still okay – 1.4m from the E, glassy early, but the swell is fading. After that, Thursday through the weekend gets messy with cross-shore winds and lumpy conditions. The swell drops off, and by Friday the 17th we got a 0.9m E swell with a strong 25 km/h cross-offshore wind, which is clean but tiny. Not worth it.

There’s a gap from the 19th to the 22nd – the surf is small and mostly crappy. The 21st Tuesday morning has a 0.6m S swell with a very long 18-second period, but it’s tiny and the wind is cross-offshore. The 22nd Wednesday morning picks up a 2.1m SSW swell with a 15-second period, and the combined energy is high (1854), but the wind is cross-shore and the break is a river, so that long-period groundswell might be too straight for the beach. It’s a toss-up.

The big one is the 24th of July, Friday morning. That’s a 3.5m SW swell with a 12-second period, and the wind is light onshore from the SE at 5 km/h. The combined energy is massive (4580), but the swell is over 2.5m, so this is for experts only. It’s a big, powerful swell, and it’s forecast to be too big for the break, so it’s gonna be heavy and dangerous.

After that, the 27th Monday morning is a nice little glassy session with a 1.2m E swell and no wind, but it’s not a standout.

So, the best bet is Tuesday morning the 14th for clean, glassy fun. The 24th is for the big-wave crew only. The rest is a mix of small or windy, so pick your days.

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.
