The Lowdown

G’day, Rusty here. Let’s be straight with you—this stretch of water is going to be a fickle beast for the next couple of weeks. We’ve got a lot of wind, plenty of rain, and a few swells that are just too big for our bones. The first real window doesn’t show up until the 14th, and even then, it’s a case of "right idea, wrong size." The standout moments are scarce, so you’ll have to pick your spots carefully.

The Overview: We’re looking at a two-week stretch where the ocean is mostly messy. The opening days are too big for this river mouth, and the middle of the period gets blown out. There’s a glimmer of hope near the end of the first week, and then a proper, clean day on the 23rd that looks like the pick of the lot. After that, it’s back to cross-shore chop and rain squalls.

Monday, 14th (Afternoon): It all kicks off with a stormy afternoon. The swell’s pushing 10 ft from the east with a 10-second period, and while the wind is just a light cross-onshore, that’s way too much water for Bonza Bay (Eastern Cape). The water is sitting at 64.2°F, which is a bit colder than usual for this time of year. The energy reading is 1855, which is strong, but it’s just going to crumble and close out. It’s not surfable; it’s a washing machine.

Tuesday, 15th: Swell drops a bit to around 6.2 ft in the morning, but it’s still too messy with a light cross-onshore, and the forecast is marginal at best. The afternoon drops to 5.6 ft, but the ENE wind kicks up to 15 km/h and puts a chop on it. Skip it.

Wednesday, 16th: The morning is a write-off. A fresh 35 km/h SW cross-shore wind with rain, and the swell is a weak 4.3 ft. The afternoon swings to a 6.9 ft SSW swell with a short 7-second period. The wind goes cross-offshore, which cleans it up, but that short period is just not going to give you any shape on a river mouth. Too lumpy and raw.

Thursday, 17th & Friday, 18th: These days are all about persistent onshore winds and rain. Thursday’s got a 4.6 ft bump in the morning, building to 7.2 ft by the arvo with a 30 km/h SE wind. Friday’s the same story: 5.9 ft to 7.5 ft of east swell with a strong cross-onshore wind. It’s all chop and lumps, and the wave energy jumps over 1000, but it’s not doing us any favors. These are days for staying dry.

Saturday, 19th: The swell jumps up to a solid 11.5 ft, and the energy reading is over 2700. Morning is ugly with 30 km/h cross-onshore winds. The afternoon goes a bit cross-shore, and the conditions are favorable for about ten minutes, but this swell is way too big for Bonza Bay. This is expert-only territory, and even then, it’s a moving mountain. If you’re not a pro, stay well clear.

Sunday, 20th (The First Glimmer): This is the first proper standout. The morning is glassy—dead calm, zero wind. The swell is still a hefty 9.8 ft from the ESE with a 10-second period, and the energy is 1743. It’s big, but it’s clean. For the experts out there, this is your window. The set waves are going to be thick and powerful. The afternoon drops to 7.9 ft and the wind goes light cross-onshore, which is okay but not as good. If you only get one session this week, make it the Sunday morning paddle-out. It’s going to be a serious session.

Monday, 21st & Tuesday, 22nd: The flush of clean conditions gets ruined by a 30 km/h SSW cross-onshore

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.
