The Lowdown
Hey, Rusty here. Let’s talk Bonza Bay. Water temp is 64°, which is about 4° colder than normal for this time of year—that’s a real cold water warning, so suit up.
Early in the outlook, Tuesday the 4th is nothing special—a 1.5m ESE swell with light cross-shore winds and a combined energy of 543, but it’s choppy and not worth paddling for. Wednesday morning the 5th is your first good slot: glassy conditions with a 1.2m E swell (346 energy) under 3 mph SSE breeze. Small, but clean and uncrowded if you’re up early.
Thursday the 6th through Sunday the 9th is a stretch of poor to marginal surf. The swell stays around 1.0m to 1.4m but with onshore or cross-shore winds and funky tides. Not much happening.
Then Monday the 10th brings a massive 4.5m to 5.0m S swell (6205 to 12398 energy). That’s way too big for this spot—expert-only and even then, the river mouth won’t hold it well. The big swell hangs around Tuesday and Wednesday, with 3.5m to 4.0m waves, but by Wednesday the wind cranks up to 22 mph, turning it into a lumpy cross-shore mess.
The real highlight doesn’t come until Monday the 17th. A clean 1.9m SW swell (1378 energy) with a light NNW cross-offshore breeze at 6 mph. That’s a proper groundswell with 12-second period—well-shaped, powerful, and best for experienced surfers. It’ll be the cleanest, most consistent session in the whole 16-day window.
After that, it fades fast. Tuesday the 18th is blown out, and the rest of the run is small and average. The gap between Wednesday the 6th and Monday the 10th is a few days of flatness, and after Monday the 17th, don’t hold your breath.
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.
