The Lowdown
G’day, I’m Rusty.
Let’s cut to the chase. The next week and a half is a real struggle. That first Sunday morning, the 16th, has a little bump of 3ft WSW swell showing, but the wind is cross-on from the SSW at 6 mph, which just chops everything up. The water is sitting at a warm 72°, which is much warmer than usual for this time of year—a nice bonus. But the energy is weak (327) and the whole period is marred by onshore winds and poor surf flags. The 27th of August Thursday morning sees a spike in size to 4ft from the West, but the period is a tiny 7 seconds, so it’s just messy windswell. The energy climbs to moderate (389), but with the wind still onshore at 6 mph, it’s still a no-go for a decent wave.
The only break in the picture is Bay Street, a beginner-friendly beach. It’s fairly consistent and exposed to the SW, and the optimal swell direction is WSW, but we just can’t get the wind and swell to cooperate for a clean session in the first nine days. The wind is always cross-on or onshore with a light breeze, so the surface is never good.
Then, on the 29th of August Saturday morning, there’s a tiny ray of light. The swell is still small at 2ft from the SW, but with a period of 15 seconds—that’s proper long-period groundswell, which will have nice shape but with long waits between sets. The combined energy jumps to strong (318), and the wind is cross-on from the SSW at 6 mph. It’s not glassy, but with that energy and the long period, the little waves will have more grunt than the size suggests. That Saturday morning is the best of a quiet bunch across the whole 16-day window. It’s still a small, gentle day, and the crowds are likely here, but if you’re a beginner looking for long, slow rides with a bit of push, that’s your window.
Overall, this is a flat patch. There are no standout days where it all clicks. Forecasts can change, but right now, you’re looking at a lot of poor conditions with only that one marginal morning on the 29th worth wetting a line.
Rusty.

Information about the Bay Street Surf forecast
The above surf forecast table for Bay Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Bay Street can be found by selecting the local surf guide option on the grey menu. Our Bay Street 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 (Bay Street) 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 Bay Street 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.
Bay Street is 2 km (1 miles) from Santa Monica. If you plan a vacation in Los Angeles County, look for hotels and other accommodation in Santa Monica. Santa Monica has rooms for a wide range of budgets as well as car hire and transport links.
