The Lowdown
Alright folks, Rusty here. Let’s be straight with you. We’ve got one spot on the board for the next two weeks, so let’s call it as it is.
Look, I’m not gonna sugarcoat it. The next ten days or so are pretty grim. From now through to about the 20th of September, we’re looking at a lot of onshore and cross-onshore wind, and the swell just isn’t delivering. Most of the time, the wave comment is "poor surf conditions." You’ll see small, weak, and choppy lines. The combined wave energy is weak, barely cracking 200 (278) at best, mostly hanging around the 150-200 range. It’s just not worth paddling out.
Now, there's a flicker of hope. From the morning of Friday the 21st of September through to Wednesday the 25th, the conditions start to look "marginal." The swell is still tiny, around 2ft to 3ft, and the water temperature anomaly is a massive 4° warmer than normal for this time of year, so the water is sitting at a balmy 73°F. That’s remarkable. But the winds remain mostly onshore, so it’s messy. The combined energy does climb up to a moderate 370 by the afternoon of the 22nd, but the direction is straight onshore.
This whole stretch is for beginners only. The break, Bay Street, is a beginner-friendly, fairly consistent spot exposed to the WSW. It’s not going to hold any real power. With the swell rarely getting over 3ft and the persistent swell direction coming from the SW or SSW, it just doesn’t match up with the optimum swell direction from the WSW. There’s no standout day here. Don’t get your hopes up; this is a classic lull. Forecasts can change, but for now, it’s a washout.
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.
