Alright, let me break this down for ya.

Right off the bat, it’s a bit of a slow burner this week. Surf picks up proper this Saturday morning, July 4th. That’s our first real window.

Look, Bonza Bay is a river mouth setup and it’s fairly consistent, so it’s our go-to even when things are quiet. For the first standout, I’m calling Saturday morning, July 4th. We’ve got a solid 8ft SE swell rolling in with a long 12-second period. That's a proper groundswell, and with glassy conditions and a light WSW breeze of 3 mph, it’s going to be clean. The combined energy is pumping at 1773 (strong). This is great for experienced surfers – it’s a bit heavy for beginners at that size. Crowds can show up here sometimes, so get in early.

The wind holds for Sunday morning, July 5th, too – glassy again with a NNW breeze at 3 mph. Swell drops to 5ft SE, still a nice 12-second period. Combined energy is moderate at 584. Clean, fun waves, but a step down in size from Saturday.

Then we hit a dry spell. Monday the 6th through Wednesday the 8th are small and weak. Tiny 3ft to 3ft surf, mostly ordinary conditions or strong winds. Not worth paddling out unless you’re desperate for a longboard.

Now, Thursday morning, July 9th, that’s a sneaky good one. Swell jumps back to 7ft from the S at 13 seconds, combined energy 1576 (strong). Offshore cross-off wind from the WSW at 9 mph, so the waves will be clean. Excellent conditions for experienced surfers again. That’s your second standout for the week.

Friday the 10th stays solid – 7ft to 8ft S swell with a very long period (14-16 seconds on Friday afternoon). That long period means better shape on a river mouth like Bonza Bay, but it can be a bit straight at beach breaks. Winds are light, but cross or cross-onshore, so not as glassy. Still worth a look for the energy (2601 on Friday arvo – very strong).

The following weekend (July 11-12) gets messy with stronger onshore winds and rain. Swell drops. Then there’s a gap of small, average days from Monday the 13th through Wednesday the 15th. Tiny waves, poor conditions.

Friday morning, July 17th – that’s over a week away, but it looks promising. Glassy conditions with a 5ft SSW groundswell at a very long 16-second period. Combined energy is 1461 (strong). That’s your long-range standout. The long period will work well at the river mouth. Clean as a whistle with a light northerly breeze.

Saturday morning, July 18th also holds a solid 7ft S swell (15-second period, energy 2472 – very strong) with clean cross-off winds. Only issue is it’s a bit big for beginners, and crowd might be around.

Overall, the first week’s best are Saturday morning July 4th and Thursday morning July 9th. The second week’s highlight is Friday morning July 17th, but keep an eye on it – long-range forecasts can shift.

Stay stoked,
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.
