The Lowdown

Alright, let's get into it.

The week starts off kinda messy for us here at Bonza Bay. We’ve got swell, but it’s coming in with a lot of cross-shore energy and the wind is just not playing ball for a clean wave. The water temp is sitting at 67°, which is pretty much normal for this time of year, so no surprises there.

Saturday the 5th is looking like a write-off. There’s some 6ft SE swell in the morning with a short 8-second period, but that ENE breeze is making it a lumpy, cross-shore mess. The energy is there at a moderate 555, but it’s not doing us any favours. By the afternoon, it drops a bit to 4ft, but the wind stays messy. Not worth paddling out for.

Sunday the 6th is even worse. The swell jumps around, but it’s all cross-on and choppy. The morning has a weak 3ft SSW swell, but by the afternoon the energy jumps up to that strong range at 2348, but the wind ruins it. That’s a miss.

Monday the 7th sees a bigger S swell hitting 7ft with a better 15-second period, but that NE wind is honking at 22-25 mph, creating a lumpy, messy cross-chop. It’s just a battle out there. Tuesday the 8th stays in that same rut – fun-looking swell but the wind is all over the place.

Wednesday the 9th drops right off. Tiny 2ft waves with no energy, the combined energy is weak at 67. Thursday the 10th and Friday the 11th aren't much better, with plenty of onshore and cross-onshore wind.

There’s a big jump in swell on Saturday the 12th, and it’s got some push to it at 7ft, but the period is a short 7 seconds and it’s onshore. Not good.

Now, here’s where it gets interesting. Sunday the 13th brings a bigger swell, but it’s too big. We’re talking 10ft to 12ft with 10-second E swell. The energy is pumping – 3132 in the morning, which is strong. But this spot can’t handle that size. It’ll be closing out and dangerous. Only for the brave, and I’m not sure it’ll even break properly.

The real standout, the session to wait for, is Monday the 14th in the afternoon. The swell is a solid 6ft, coming from the SSW with a clean 12-second period. And the wind… it’s dead glassy. The energy is strong at 1289. This is what we’ve been waiting for. The conditions are going to be excellent. This is the best call of the whole run, no question.

Tuesday the 15th has a bit of leftover glass in the morning with a fun 3ft SSW swell, but it’s not as good as the day before. The rest of the second week gets pretty ordinary. There are some cross-offshore days, but the swell is small or the wind is just too strong. The 17th has a decent 8ft SSE swell, but it’s a short 8-second period and onshore. The 18th and 19th see a return of 7ft+ E swell, but it’s all cross-shore and lumpy.

So, to keep it simple: you’ve got one true standout – Monday the 14th. Head down in the afternoon for clean, glassy conditions and some proper SSW groundswell. The rest is either too wind-blown, too big, or too weak to get too excited about. It’s got that feeling of promise, but the ocean just isn’t delivering the goods consistently this time.

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.
