The Lowdown
Alright, let me break it down for Oyster Bay.
We’ve got a mixed bag coming our way, and the ocean is going to be a bit of a beast at times. The big story right now is that it might be too much power for the spot. On Wednesday the 26th of August, a solid 10-foot southerly swell with a 16-second period is hitting, and the combined energy reading is 5322 – that’s a ton of water. For Oyster Bay, a sandbar that doesn’t always fire, that’s a lot to handle. The wind is a strong cross-off at 19 mph, keeping things clean, but this is for the experienced guys only. Beginners, stay out of the water.
It backs down on Thursday the 27th to a 7-foot SSW swell, but the call is marginal. The wind is lighter, but the quality just isn’t there. Then we get to Friday the 28th of August, and that’s the day to circle. The swell drops to a much friendlier 5 feet from the south, and the wind goes light offshore out of the NNE at 6 mph. That’s glassy, clean conditions. With a moderate wave energy of 953 and an 11-second period, it’s not epic, but it’s the most surfable the bay is going to be for a while. This is your best shot.
After that, the weather turns nasty. From late Saturday the 29th through the start of September, it’s a mess of strong cross-onshore winds and lumpy, blown-out surf. The swell size keeps coming, even hitting 15 feet on the 3rd of September, but with those winds, it’s unsurfable. This stretch looks way better for kite surfers.
There’s a flicker of hope later. On Friday the 4th of September, a 10-foot southerly swell returns with clean cross-off winds, but again, that’s too big for this break to work well. Further out, Sunday the 6th of September shows a promising 6-foot southerly groundswell with a 13-second period and clean, moderate cross-off winds. That’s a better option, but it’s a long way off.
So, here’s the call: If you can get out, make it Friday morning the 28th of August. That 5-foot south swell with an offshore breeze is your cleanest, most manageable window. After that, there’s a long dry spell until that Sunday the 6th of September, which looks promising but is still a ways out.
Stay patient and keep an eye on the horizon.

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.
