The Lowdown
Alright, folks, Rusty here. Let's have a look at what Bonza Bay has in store for us over the next sixteen days.
Right off the bat, the immediate outlook is a bit of a bummer. We’ve got a stretch of nothing but marginal and poor conditions through the rest of this week and into the weekend. The wind is consistently cross or cross-on, and the swell is all over the place without any real quality. There’s a bit of energy here and there – but the conditions just aren't coming together. You’ll be scratching your head trying to find a decent wave. This dry spell really runs from now right through Sunday, July 19th.
Now, let’s talk about the first real glimmer of hope. On Monday, July 20th, things look like they’re finally going to turn. The morning is calling for glassy conditions, with a clean 4ft swell rolling in from the SSW. The energy is moderate and the period is a solid 13 seconds, so there’ll be some decent lines. This is a river break, so that longer period groundswell might not be the best for the river mouth, but with glassy, clean conditions, it’s worth a look. The water temp is sitting at 65°, which is a bit colder than normal for this time of year, so you might want a thicker wetsuit. It’s not a standout, but it’s the first real chance to get wet.
The real standout, the one you want to circle on the calendar, is Tuesday, July 21st. The morning is forecast to be glassy again, with a 4ft swell from the S, but the period jumps to a very long 14 seconds. That’s groundswell, and it’ll bring some proper energy. However, and this is a big caveat, the afternoon session shows a massive 10ft swell from the SSW with a huge energy reading. That’s a massive jump, and the file says it’s predicted to be too big for this break. The morning glassy session with the 4ft groundswell is your best bet, but get in early before that giant swell fills in.
Another good window opens up on Wednesday, July 22nd. The afternoon is looking excellent for experienced surfers, with glassy conditions and a clean 6ft swell from the S. The combined energy is strong. This is a proper session for anyone who knows what they’re doing.
Now, hold on to your board shorts, because the end of the week gets wild. On Thursday, July 23rd, we’re looking at a huge 13ft swell from the SSW in the morning, with a massive energy reading – that’s huge. The wind is cross-offshore, which is clean, but it’s just too big for Bonza Bay. This is experts-only territory, and even then, it’s probably too much. The afternoon is still 12ft with even more energy. This is less about surfing and more about staying out of the way.
Let’s settle in for the second week. The window around Saturday, July 25th morning looks promising, with glassy conditions and a 5ft S swell. It’s a nice, manageable size for a Saturday morning. The rest of the week is a mix of marginal and poor conditions, with winds picking up again. The period on the 28th of July gets up to a very long 18 seconds, but the swell is small and the wind is messy.
To wrap it up, the best of the best is the glassy morning session on Tuesday, July 21st with that 4ft, long-period groundswell. The Wednesday afternoon on the 22nd is a close second for more experienced surfers. The rest of the time is a waiting game. Don't force it.
Rusty, signing off.

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.
