The Lowdown
Alright crew, let’s talk about Bonza Bay. This is the only spot on the cards for the next 16 days, so we’re sticking with it. The water’s sitting at 70°, which is a touch warmer than normal for this time of year – nothing crazy, but your springsuit might feel a bit more comfortable than usual.
The forecast kicks off Tuesday, July 28th, but honestly, it’s a rough start. We’ve got a 7ft SSE swell with a short 8-second period, and a cross-on wind from the SSE at 12 mph. The energy’s there (1306), but it’s choppy and messy. Not the kind of day that gets you out of bed early. The afternoon stays cross-on and the swell holds, but the quality’s still poor.
Wednesday the 29th drops right down – 3ft of SSW groundswell with a long 14-second period, but the wind is cross-on from the ENE, so it’s still not clean. The energy’s lower (886), and it’s just marginal. Afternoon picks up a little to 5ft ESE, but again, the wind is ruining the party.
Thursday the 30th offers a glimmer. The morning has a light SSW breeze at 6 mph, cross-shore, with a 6ft ESE swell. The energy is moderate (979), and the wind is light enough that it might not be too chopped up. The afternoon goes onshore, so the morning is the pick. Still, it’s marginal.
Friday the 31st into Saturday the 1st of August is a write-off. The wind kicks up hard – fresh to strong breezes from the NE, cross-shore, making the surface lumpy and messy. The swell is 6ft to 8ft, but the wind is just too strong. This is kite-surfing territory, not paddle surfing.
Sunday the 2nd isn’t much better. NE wind at 12-16 mph keeps things messy. The swell is 6ft to 7ft, but the period is short (8 seconds), so it’s weak energy (551-654). Not worth it.
Monday the 3rd of August sees a glimmer of hope. The wind drops to a light S breeze at 3-6 mph, cross-on, with a 5ft E swell. The energy is still moderate (647), but the light wind means the surface might clean up a bit. Still marginal, but the best of the first week.
Then we hit a gap. Tuesday the 4th through Thursday the 6th is a mix of small swell (2ft to 6ft) and poor to marginal conditions. The wind is mostly cross-shore, but the energy is weak (under 600), and the swell period is short or just okay. Nothing to get excited about.
Friday the 7th of August brings a bit more hope. The wind goes cross-offshore from the WSW at 12 mph, with a 5ft SSW groundswell (13-second period). The energy is solid (904), and the wind is clean. This is the best of the first week. The afternoon goes cross-shore, so get in early.
Saturday the 8th still has a decent 5ft SSW swell with a long 15-second period, but the wind is cross-shore from the NE at 12 mph. The surface will have a cross-chop, but the energy is strong (1134). It’s not perfect, but it’s surfable for the experienced.
Now, the standout. Sunday the 10th of August – hold on to your board. The morning shows a massive 13ft SW swell with an 18-second period. The energy is off the charts (11627). The wind is light cross-shore from the SW at 9 mph. This is a massive groundswell, and the forecast says it’s too big for this break. This is for experts only. The wave direction is solid SW, and the period is very long, so it’ll be powerful and clean. But at 13ft, it’s a beast. If you’re not a seasoned charger, sit this one out. The afternoon drops to 5ft, but the morning is the big one.
Monday the 11th of August is another big one – 12ft SSW with a 15-second period. Again, too big for the break, but the energy is massive (8449). The wind is cross-shore from the NE, so it’s not as clean, but for the brave, it’s a day.
The last few days, Tuesday the 12th and Wednesday the 13th, settle down to 7ft to 7ft S swells with moderate periods. The wind is light cross-shore, so the surface should be okay. Energy is still strong (1646-1566), and it’s a good finisher for the more experienced.
The real standout? The morning of Sunday, August 10th. That 13ft SW groundswell with light wind is the big one, but it’s only for the experts. The best for the average surfer? Friday the 7th of August morning, with clean cross-offshore wind and a solid 5ft groundswell.

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.
