The Lowdown
Alright, let’s break it down for Oyster Bay, ’cause that’s the only spot we’re lookin’ at here.
Things start off pretty average. Water temp is 62°F, which is about 4°F colder than normal, so you’ll feel that chill. The first few days are a mess with onshore winds and a swell that just won’t line up right.
Sunday the 30th and Monday the 31st are rough. Sunday has a moderate cross-onshore breeze with a 8ft SW swell, choppy and poor. Monday morning cleans up a little with light wind, but it’s still cross-onshore and marginal. Not worth your time.
Tuesday the 1st of September is lumpy. Swell is 8ft to 8ft from the SW with moderate to strong energy, but the wind stays cross-onshore and choppy.
Wednesday the 2nd of September is the one standout in the near term. Morning sees a 10ft SW groundswell with a 14-second period, and the wind turns light cross-off from the ENE. The water is clean, and the energy is strong. That’s a solid, powerful swell, but at 10ft it’s big for Oyster Bay – experts only. Afternoon stays big at 10ft but gets a stronger cross-shore wind, adding some cross-chop.
After that, it goes downhill. Thursday the 3rd and Friday the 4th are blown out with strong winds and lumpy conditions. Saturday the 5th has smaller 4ft to 5ft SSW swell and clean conditions, but the energy is weak and it’s poor quality.
The second week starts with Sunday the 6th of September – a 8ft SSW swell with a 14-second period and clean cross-off winds, but gusty at 22 mph. Monday the 7th is a write-off with near-gale winds. From Tuesday the 8th onward, it drops into tiny, weak surf with clean but flat conditions. Energy is very low.
Late in the window, Saturday the 12th of September brings a 8ft SW swell with a 14-second period and clean cross-off winds. Strong energy, but the wind is fresh at 22 mph. Sunday the 13th has similar but smaller 6ft to 6ft SW swell. Both are clean but marginal for quality. By Monday the 14th, the wind goes back cross-on and messy.
Bottom line: Wednesday the 2nd of September is the best day, but it’s big and only for experts. The rest is patchy with a few clean, smaller sessions in the second week. Oyster Bay is an inconsistent spot, and this stretch shows it.
Stay salty.

Information about the Oyster Bay Surf forecast
The above surf forecast table for Oyster Bay provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Oyster Bay can be found by selecting the local surf guide option on the grey menu. Our Oyster 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 (Oyster 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 Oyster 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.
Oyster Bay is 24 km (15 miles) from the city of Kruisfontein. If you plan a holiday in Eastern Cape (South), look for hotels and other accommodation in Kruisfontein. Kruisfontein has rooms for a wide range of budgets as well as car hire and transport links.
