The Lowdown
Howdy, Rusty here. Let's chew the fat on Oyster Bay.
The water's a chilly 61°, which is a good 5° colder than usual for this time of year, so you'll be needing a steamer. The first few days are a complete bust. Saturday the 8th of August is a mess, with strong cross-onshore winds and a big, ugly 8ft to 8ft SW swell. The combined energy is massive (2394), but it's unsurfable. Sunday gets even worse with a 10ft SW swell and fresh cross-onshore wind. It's a no-go for a paddle. Monday, the 10th, is just as bad with moderate cross-onshore chop. This is kite-surfing territory, not surfing.
We catch a break on Tuesday the 11th. The swell drops to 8ft from the SSW, and the wind shifts to a cross-off from the east. It's still a fresh breeze, so it's clean but bumpy. The combined energy is still high (2394), but it's a marginal start. The next few days are weird, with a small, long-period swell (20-21 seconds) that's clean but lacks punch.
Now, here's the gold. Friday the 14th of August. The morning is a thing of beauty. A light offshore from the north, glassy clean, with a 4ft SW groundswell. The combined energy is solid (1345), and the period is 15 seconds, which is a proper long-range groundswell. This is the best on offer, and it's a window for experienced surfers to get some clean, lined-up waves. The afternoon bumps up to a 8ft easterly swell with a shorter period, but the wind stays offshore from the NE.
After that, it's back to the grind. The rest of the month is a struggle with onshore winds, smaller swell, and a lot of chop. The 18th and 19th offer some clean-ish conditions, but the swell is inconsistent and weak. The 22nd and 23rd are a similar story, with a moderate east-northeasterly wind and a 7ft SW swell. It's not the magic we saw on the 14th.
So, the bottom line is this is a tough stretch for Oyster Bay. The first week is a write-off, but the 14th of August is a true standout. It's an inconsistent spot that rarely breaks well, but when it does, it's worth the wait. Don't get your hopes up for the rest of the window.
Rusty.

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.
