The Lowdown

Alright, let’s talk about Oyster Bay.

Look, this sandbar is known for being inconsistent, and right now we’re seeing that. The first surf on offer is Monday morning, 20 July, with a small 4ft SE swell carrying a moderate 12-second period. The water’s sitting at 63.7°—a bit colder than usual for this time of year, so you’ll want a decent wetsuit. Wind’s cross from the west at 12 mph, and the combined energy is only moderate (616). It’s marginal, nothing to get excited about.

Monday afternoon shifts to a 6.6ft SW swell, but the wind turns cross-onshore and it gets choppy—not worth it. Tuesday morning, 21 July, has a 6.2ft SW groundswell with a long 15-second period, but again cross-onshore wind and light ripples. The afternoon bumps up to 8.2ft SSW, period 14s, but still cross-onshore. The energy picks up (3220), but the wind spoils it.

Now, Wednesday morning, 22 July—that’s a standout. The wind swings to offshore from the NNE at 6 mph, glassy. Swell is a solid 6.9ft from the SW, period 12 seconds, and the energy is strong (1549). It’s clean, and the break should be well-shaped for intermediate and above. Crowds are possible at Oyster Bay, but with the inconsistent nature, it might not be packed. This is your best bet early on.

Wednesday afternoon gets wrecked by a fresh onshore wind—lumpy, skip it. Thursday is a write-off: strong winds, messy, and the swell jumps to 11.5ft on Thursday afternoon but with 28 mph cross-onshore. Friday morning, 24 July, brings a massive 13.1ft SW groundswell with a very long 16-second period and offshore wind—clean as a whistle. But that swell is too big for this sandbar. Only for experts who know the inside bowl, and even then, it’s risky. The energy is extreme (7336). If you’re not a pro, stay out.

Saturday morning, 25 July, is another good window: 8.2ft SW, 14s, cross-off wind from the ENE, clean. The energy is strong (2618). Excellent for experienced surfers. Sunday morning, 26 July, is also choice: 6.9ft SW, 12s, offshore from the NNE at 12 mph, clean again. Moderate energy (1324). That’s a solid pick.

After Sunday, the window gets messy. Monday 27 July morning has a smaller

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.
