The Lowdown

Alright, Rusty here with a look at the weeks ahead for Bonza Bay. This river mouth setup is exposed to the south, so it's gonna be a tale of waiting for the right southerly push.

The water is sitting at 65°, which is a bit colder than we usually have this time of year – a solid 3° cooler, so you'll feel that chill if you're not suited up right.

We're looking at a bit of a slow start. The first couple of days are a bit of a write-off with a small, weak E swell and messy cross-shore breezes, so don't rush out the door just yet. The real action starts to build through the middle of the week.

Thursday the 16th morning is where it starts to get interesting. The wind is a nice cross-offshore breeze from the WSW, cleaning up a 6ft swell from the SW. The energy is kicking in strong (1388), and the conditions are set to be clean. This is a solid intermediate wave, and with that side-offshore wind, it's going to reel off nicely. Keep in mind, though, it's a river mouth, so it can get a bit of a crowd on a day like this.

Friday the 17th morning is the standout of the first week. We're looking at a proper 8ft groundswell from the SW with a 13-second period (2288 energy). The wind is again a clean cross-offshore from the WSW. That's a solid, powerful wave. For the experienced crew, this is going to be the go. It's a bit too much size for beginners, but for the rest of us, it's going to be a ripper morning.

The following week has a funky window. Tuesday the 21st morning is a real curveball. The wind is dead calm, glassy, and the swell has dropped to a clean 3ft, but it's a long-period 15-second groundswell. That's a super clean, long-period wave that'll hold up nicely on the river mouth bank. For a quiet, glassy session, that's your pick.

Later that week, Thursday the 23rd morning is another big one, but it's pushing the limits. An 8ft, 15-second SSW groundswell with a strong 2956 energy rating. The wind is cross-offshore again. This is full-on, expert-only territory. It's a serious amount of water moving around, and the period is long, so it'll be a heavy, powerful wave. Not for the faint-hearted.

The very end of the run, Sunday the 26th morning, offers a final chance at a clean, small wave. A 2ft, 16-second groundswell with a clean cross-offshore breeze. It's small, but it'll be clean and glassy with that long period.

Overall, the best window is the Thursday 16th to Friday 17th stretch, with Friday morning being the standout for the experienced crew. The glassy Tuesday the 21st is a sneaky good option for the early crew.

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.
