The Lowdown

Alright, mates, Rusty here. Let’s talk about the surf ahead. It’s a bit of a patience game, I’ll tell you that right now.

We’ve got one big swell to get excited about, and it’s coming next Monday, the 14th. That’s your standout. But the lead-up is messy, and the tail end has its issues.

From Thursday the 10th through Saturday the 12th, it’s pretty poor. Onshore and cross-shore winds, choppy surfaces, and small surf, maybe 2 to 5 feet. Not worth paddling out for.

Sunday the 13th sees the swell start to climb, but it’s coming in with strong east-northeast winds and storm clouds. It’s going to be a messy 8 foot. Not pretty.

Now, Monday the 14th is the big one. The swell hits a solid 10 feet from the east with a 10-second period. The energy is huge. But the problem is, that’s simply too big for Bonza Bay. The forecast is plain about it. Unless you’re a pro, sit this one out. The cross-shore wind will also make it tricky.

Tuesday the 15th is a step down, around 5 to 6 feet, but the wind swings more onshore, making it choppy and on the poorer side.

Midweek, Wednesday the 16th, the wind goes wild, with gusts up to 40 km/h from the southwest. There’s a clean window in the morning with a long-period, 17-second south-southwest swell, but it’s under 3 feet. Not much to grab onto.

The week after is a bit of a mixed bag. There’s another south-southwest pulse coming through on Monday the 21st, with 7-foot waves and a 12-second period. Lots of energy, but the winds are all over the place, making it lumpy and rough.

The 22nd brings onshore southeasterlies with 6-foot surf, but it’s not clean. And the last chance is Thursday the 24th, with an 8-foot easterly swell, but again, fresh northeast winds will chop it up.

So, the one to watch is Monday the 14th, but it’s a case of “too big for the bay.” Everything else is a fight for anything clean. The water temp is normal for this time of year, so a good wetsuit is still needed.

Keep an eye on it, though. Things can change.

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.
