The Lowdown

Alright, let’s get into it. Thompsons Bay is the only spot on the radar, and it’s a sheltered, fairly consistent intermediate break. The water here is running at 73°, which is pretty much normal for the time of year.

First up, we’re looking at Thursday the 23rd of July. There’s a 2ft swell from the SSW, 14-second period, and the combined energy is moderate at 418. But the wind is cross-on, and the conditions are already described as poor. This one’s a no-go.

Friday the 24th gets ugly. A massive 12ft swell from the S hits, with only a 9-second period. The wind is howling out of the SSW at 31 mph, cross-on, and the energy is way up at 2256. It’s a near gale, blown out. This is for experts only, and even then, it’s not good. The afternoon is a little less intense at 10ft, but still 22 mph winds and lumpy. Stay out.

Saturday the 25th drops a bit. Morning is 6ft from the SSE, 9-second period, energy at 903. But the wind is still cross-on, and it’s fairly choppy. The afternoon improves a little: 6ft, 10-second period, energy 843, and the wind turns onshore but light. The forecast says “marginal,” and I’d agree. It’s not great.

Sunday the 26th is a write-off. 5ft in the morning, but cross-shore wind at 12 mph, and the energy is down to 569. The afternoon is even smaller at 3ft, but the wind is still cross-shore, and the period drops to 13 seconds. That long period stuff is better for points and reefs, but here it’s just messy.

Monday the 27th is tiny. 2ft in the morning, SSW swell, 15-second period, energy 393. The wind is light cross-on, but there’s not enough to ride. The afternoon is even smaller at 1ft.

Tuesday the 28th sees a bump. 7ft in the morning from the SSW, but only 7 seconds. That’s a short-period, choppy mess. Energy is 570. Wind is cross-on at 16 mph. The afternoon is 7ft, same story. Not for paddling, maybe for kites.

Wednesday the 29th brings a 10ft SSE swell, 10-second period, energy at 1956. The wind is cross-shore at 12 mph, but it’s light rain. The forecast says “marginal.” The size is big, over 8ft, so this is experts only. The afternoon is 8ft, same story.

Thursday the 30th has 8ft from the SE, 10-second period, energy 1545. The wind is cross-offshore from the WSW at 22 mph, and the conditions are described as “clean.” That’s a positive. But the size is still big, and the wind is fresh. It’s a tough one.

Friday the 31st is heavy rain and 7ft from the SE, 10-second period, energy 919. The wind is onshore at 19 mph. The afternoon is 7ft, cross-on and choppy. Not good.

Saturday the 1st of August is 6ft from the ESE, 11-second period, energy 836. The wind is light cross-shore, but there’s light rain. The afternoon is similar at 5ft. Marginal.

Sunday the 2nd of August is the best of the bunch. 4ft from the SE, 9-second period, energy 305. The wind is cross-offshore from the NE at 9 mph, and it’s “clean.” The conditions are described as “surfable but very ordinary.” The afternoon is 3ft, also clean. This is the standout window. It’s not pumping, but it’s the cleanest we’ll see.

Monday the 3rd drops back to 2ft, clean, but tiny. The rest of the week is small, with 3ft to 4ft, and poor conditions.

Friday the 7th of August shows a spike: 7ft from the SSE, 9-second period, energy 1153. The wind is cross-shore at 9 mph, and the forecast says “marginal.” It’s interesting, but it’s a long way out.

The long and short of it: the best bet is Sunday the 2nd of August. It’s clean, small, and surfable. Everything else is either blown out, too big, or just plain messy.

Information about the Thompsons Bay Surf forecast

The above surf forecast table for Thompsons Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Thompsons Bay can be found by selecting the local surf guide option on the grey menu. Our Thompsons 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 (Thompsons 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 Thompsons 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.

Thompsons Bay is 3 km (2 miles) from the city of Ballitoville. If you plan a holiday in KwaZulu-Natal North Coast, look for hotels and other accommodation in Ballitoville. Ballitoville has rooms for a wide range of budgets as well as car hire and transport links.
