The Lowdown
Alright, folks, Rusty here. Let’s break down Oyster Bay over the next couple weeks.
We start off slow. The first real surf shows up on Friday, July 31st, with a 5ft swell out of the southwest, but the wind is a stiff 30 km/h from the ENE, making it cross-off but bumpy. The combined energy of all swells directed here is strong at 1240, and the water is 64°, which is a bit colder than normal for this time of year. The afternoon gets worse with a 7ft east swell and howling 40 km/h winds. Not worth it.
Saturday, August 1st, is a total loss. The swell hits 8ft from the east, but with 40 km/h winds, it’s a mess.
Sunday, August 2nd, is where we see a little hope. The morning brings a 7ft east swell, winds drop to 20 km/h, and the energy is cranking at 1412. The afternoon actually gets interesting: a 7ft swell from the ESE, period stretching to 12 seconds, with combined energy at 1516. It’s still cross-off, but it’s cleaner. This is the best of the first week, but it’s still only so-so.
Monday, August 3rd, the morning has a 6ft ESE swell with a 10-second period, and the wind is a light 10 km/h from the NE. The energy is moderate at 828, and the conditions are clean. A good pick for a quiet session. The afternoon drops off.
Now, get ready. Thursday, August 6th, we get a big pulse. The morning shows a 13ft southwest swell with 30 km/h cross-on winds – a kite day, not a paddle day. The afternoon is a standout: a 15ft southwest swell, 14-second period, with a light 10 km/h onshore wind. The energy is enormous at 6857. But it’s way too big for Oyster Bay unless you’re an expert.
Friday, August 7th, is the absolute best of the outlook. The morning gives us a 12ft southwest swell, 14-second period, and the wind is a glassy 15 km/h from the NNE – offshore, clean, perfect. The combined energy is 4001. The afternoon holds a 10ft southwest swell with light ENE winds. This is the one, but it’s over 8ft, so experts only.
After that, the second week gets messy. Saturday, August 8th, and Sunday, August 9th, are blown out. Monday, August 10th, is a write-off with near gale-force winds. From Tuesday, August 11th, through to Saturday, August 15th, the swell drops to 3ft or less, with onshore or cross-shore winds, and the energy fades to weak levels (156 to 170). A long, flat finish.
So, your best bet is Friday, August 7th, for the experts. For everyone else, Sunday afternoon, August 2nd, or Monday morning, August 3rd, are your cleanest, most manageable waves.
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.
