The Lowdown
Alright, Rusty here with the outlook for Bonza Bay. We've got a bit of a mixed bag coming, but there are some definite moments to keep an eye on.
Right now, things are pretty average. The water's sitting at 64°, which is a solid 5° colder than usual for this time of year, so you're going to want a thicker wetsuit. The first session worth paddling out for is on Sunday morning, July 19th. We've got a clean 4ft south swell with a period of 10 seconds and glassy conditions. It won't be the biggest day, but with no wind, it'll be clean as a whistle. The combined swell energy is moderate at 589.
Monday morning, July 20th, looks even better. A 5ft southeast swell with a long 12-second period is showing, and the wind is offshore from the southwest. That's clean surf again with moderate energy (796). This could be the pick of the first week.
Now, we have to wade through a lot of muck from Tuesday through Thursday with bumpy winds or onshore slop. But hold onto your board, because Friday morning, July 24th, is where it gets interesting. A solid 8ft south-southwest groundswell is due, with a very long 17-second period. This is powerful stuff, with strong energy (3273) behind it. The wind is a light cross-shore, but the swell is pushing the limits for a river break. It's going to be big and long-period, which can make a river mouth get real shifty. This is really only for experienced surfers.
Saturday morning, July 25th, still has plenty of energy left over, with a 6ft south-southwest swell and a 15-second period (energy 1301). The wind is light, keeping things clean-ish. The swell is still on the bigger side for intermediates.
The following week is mostly a write-off as we're hammered by strong winds and onshore chop, with a couple of big, stormy swells that look more like a kiteboarding nightmare than a surf session. The only slight possibility could be Saturday, August 2nd. That morning there's a massive 12ft east-southeast swell predicted, but the wind is light, and the break is going to be way too big. It's genuinely dangerous for anyone but the most expert charger.
So, my pick of the entire outlook has to be Monday morning, July 20th. It's the cleanest combo of a decent-sized, good-period swell with an offshore wind. Sunday morning, July 19th, is the close second for its perfect glass. Keep an eye on Friday the 24th and Saturday the 25th if you've got the skills to handle big, powerful, long-period waves.
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.
