G’day, I’m Rusty. Let’s talk about what’s coming up at Bonza Bay. This is a river-mouth spot, exposed to the south, and it pumps fairly consistently. The water is sitting at 64°, which is about 4° colder than normal for this time – that’s a real chill, so bring a thick wetsuit.

We start Sunday the 12th with a clean morning. Glassy, no wind, a 4ft south swell at 12 seconds. That’s a proper groundswell, combined energy at 765 (moderate), and it’s got some weight. The rain showers won’t matter. The afternoon turns cross-on with a light breeze, so get out early. Monday the 13th is the pick. The morning is glassy with a 5ft ESE swell, but it’s short-period at 8 seconds. The afternoon though is a gem: glassy, 7ft east swell at 8 seconds, combined energy at 975 (moderate to strong). It’s a bit windswelly, but for a river mouth, it’ll be fun and punchy. This is the best session of the first few days.

Tuesday the 14th morning is glassy again, 6ft east swell at 9 seconds, 617 energy (moderate). The afternoon gets a cross-on breeze, so it fades. Wednesday the 15th has a clean morning with light cross-off wind and 5ft east swell at 10 seconds, but the afternoon turns poor. Thursday the 16th is marginal – tiny 3ft long-period SSW swell (14 seconds), pretty shape but small. Friday the 17th afternoon sees a big jump: 8ft SSW swell at 13 seconds, but it’s cross-on with rain, and combined energy hits 2112 (strong). That’s a lot of power with bad wind – better for kite surfing than paddle surfing.

Saturday the 18th is lumpy with fresh cross-wind, 7ft south swell at 14 seconds (2438 energy, strong). Not a surf day. Sunday the 19th afternoon is clean: light cross-off wind, 7ft east swell at 9 seconds, 971 energy (moderate). That’s a nice one. Then we hit a gap. Monday the 20th through Wednesday the 22nd are all poor or marginal. Thursday the 23rd morning is clean, light cross-off, 3ft long-period SSW swell at 14 seconds, 776 energy (moderate) – small but clean. Friday the 24th is marginal.

Looking into the second week, Sunday the 26th morning is a monster: 13ft SW swell at 14 seconds, combined energy at 8446 (very strong). That’s way too big for this break – only for experts, and the forecast says it’s too big. Monday the 27th morning is the real standout: glassy, 7ft south swell at 13 seconds, 1576 energy (strong), and it’s calling excellent conditions for experienced surfers. That’s the one to mark on the calendar.

So, best bets: Monday the 13th afternoon for the 7ft glass, and Monday the 27th morning for the clean power. The middle of the week (20th to 22nd) is a bust. The long-range stuff is promising but less certain.

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.
