The Lowdown

G’day, Rusty here with the imperial read. Bonza Bay is a river mouth exposed to the south, and the next 16 days look bleak for a good surf. There’s a serious dry spell with no real recommendations until late in the second week.

Overall Pattern: The first week and a half is dominated by onshore and cross-shore winds, making nearly every session poor or marginal. The combined swell energy is moderate to very strong, but the wind direction trashes the surface. A big, powerful swell shows up around the 22nd, but it’s too big for this break.

Bonza Bay – Monday 10th afternoon is a write-off: 1.3m (4 ft) SE swell (8 seconds) with onshore wind and light rain. Water temp is 19°, a bit colder than normal.

From the 11th through the 20th, it’s a grind. Swell heights range from 0.6m (2 ft) to 2.3m (8 ft), but the wind is always cross or cross-on, with fresh breezes and lumpy conditions. The best of a bad bunch is Saturday 15th afternoon: 1.8m (6 ft) E swell (12 seconds) under clear skies, a gentle cross-shore breeze, and moderate combined energy (1316) – marginal but you might find a couple.

The big pulse hits Saturday 22nd August: massive 3.5m to 4.0m (12 to 13 ft) ESE swell (11-12 seconds), combined energy at 4704. The wind is cross from the SW. This is expert-only territory – at over 2.5m (8 ft) it’s too big for most, and the river mouth will close out and get chaotic. Not a goer.

After that, the 23rd drops to 2.0m (7 ft) and stays messy. The run ends with poor, onshore wind and tiny swell through the 25th.

Final Call: No true standout. The only half-chance is Saturday 15th afternoon for a marginal session. For the big swell on the 22nd, kite surfers would have a field day in those strong cross-shore winds, but paddle surfers should look elsewhere.

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.
