The Lowdown
Alright, let’s break it down for Oyster Bay, using feet and knots.
The first few days are a bust. Strong onshore winds and a messy ocean. Friday morning there’s a 10ft SW swell, but it’s cross-on and choppy. The energy is huge, but the wind is just trashing it. Saturday and Sunday are even worse – gale-force winds and poor surf. Just stay home.
Things start to turn on Monday the 20th. The wind goes to the NE, clean cross-off. The swell is 6ft from the SW, with a 11-second period. Energy is still solid. That morning is decent for experienced surfers. But the real standout is Tuesday the 21st. The morning is glassy. Wind is 3 knots from the NE, and the swell is 5ft from the SW with a very long period of 15 seconds. That’s proper groundswell. The energy is 1278. On a sandbar, that long period can make the waves a bit too straight, but it’s the cleanest, most powerful session on offer. The water temp is 64°F, which is a bit colder than normal for this time of year.
Then we get a massive pulse from the 22nd through the 24th. Swells of 13ft to 15ft from the SW, with energy readings over 9000. That’s way too big for this spot. Even if the wind is glassy, like on the 23rd and 24th, those waves are just going to close out.
The last week of July into August sees the swell back down. The 29th and 30th are looking good. On the 29th, a 7ft ESE swell with a clean offshore wind from the N. Energy is 1485. Clean, powerful. The 30th drops to 5ft from the E, still clean. The 31st bumps up to 8ft from the SSW, but with light offshore/glassy conditions – another good day.
Best bet: Tuesday the 21st morning. That glassy, long-period groundswell is the pick of the lot. The stretch from the 29th to the 31st is your next best call. Skip the first weekend and the mid-week giant swell.

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.
