Alright, grab your board. Rusty here, and I’ve got the lowdown on what’s cooking for Bonza Bay over the next couple of weeks.

We’ve got a river break on our hands, and overall, it’s a mixed bag of big, powerful swells with some windows of clean conditions, but also plenty of wind and chop to deal with. The real standout window jumps out at us early on.

First up, this Saturday morning, July 4th, Bonza Bay is looking firing. We’ve got a solid 8 ft SE groundswell with a 12-second period, and it’s pushing a big chunk of energy – 1773, which is strong. The wind is glassy from the WSW at only 3 mph. That’s clean, powerful surf, but at that size, it’s for experienced surfers only. The water temp is sitting at 65°, which is over 4° colder than normal for this time of year, so you’ll want a good wetsuit. It’s a river break, so that long-period SE swell should wrap in and set up nicely.

Moving into Saturday afternoon, the swell drops slightly to 7 ft with a cross-shore wind making things a bit lumpier, but it’s still sizable. Sunday morning (July 5th) is another good one; the swell drops to a more manageable 5 ft, still from the SE with that solid 12-second period, and the wind swings around to a light N at 3 mph, going cross-offshore. That’s what you call very good, clean conditions. Energy is down to 633, so it’s moderate, but the quality is on point.

Sunday afternoon gets a bit blown out with an onshore breeze, and from Monday the 6th through to Wednesday the 8th, the wave heights drop way down. You’re looking at knee-high stuff, under 3 ft, with only weak energy. The water stays cold, and there’s nothing to get excited about.

Now, here’s the next proper highlight. On Thursday morning, July 9th, a new pulse of swell arrives. We’re talking a 7 ft S groundswell with a very long 14-second period and strong energy of 1804. Wind is light cross-offshore from the WSW at 6 mph, keeping it clean. That’s excellent surf for stronger paddlers, but again, solid size. That big groundswell will be best where it can wrap in, with those long lines. Thursday afternoon stays rideable but gets a bit messy with cross-shore wind.

Friday the 10th and Saturday the 11th are still showing decent swell height (7 ft to 8 ft) and strong energy, but the wind is blowing cross-shore or cross-onshore, making it choppy and poor. That long-period S swell on Friday afternoon has a period of 16 seconds, which is very long, so it will have real power but will be a battle in the wind.

After that, we hit a flat spell from Sunday the 12th through to the middle of the next week. The swell drops out, and the wind is messy. There is a little bump on Monday morning, July 13th, with a glassy 4 ft easterly windswell – tiny period around 8 seconds, so not much oomph, but surprisingly clean conditions.

The real next possibility comes on Friday morning, July 17th. We’ve got a 3 ft E swell, wind is light cross-offshore from the NE at 6 mph, and the conditions look good for a cleaner, smaller session with just moderate wave energy.

Apart from the Saturday and Sunday morning windows at the start and that Thursday the 9th, much of this period is either too small, too windy, or too messy. The standout is without a doubt the glassy Saturday morning with that solid 8 ft swell.

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.
