The Lowdown
Alright, Rusty here again, translating it into feet and miles per hour for you.
Let’s be real about this one: it’s a flat, frustrating stretch for the most part. There’s a big gap of poor conditions for the first week and a half before the water starts showing a little more life toward the end of the run.
At Bay Street, from Friday the 11th of September all the way to around Tuesday the 22nd of September, it’s “poor” with swell heights from about 1 ft to 3 ft. Winds are mostly cross-onshore or onshore from the south or southwest, which is the wrong direction for this break – it really needs a WSW swell to work. The swell periods vary but are often 14 to 18 seconds, which means there is some groundswell mix, but the energy is weak (combined energy mostly between 100 and 279, so low to moderate). Water temp is about average for the time of year, no big changes. The waves are just too small and bumpy.
From Wednesday the 16th of September onward, things go from “poor” to “marginal” a few times. On Sunday the 20th of September morning, the energy climbs to 403 (moderate) with a 2 ft swell from the SW, period of 18 seconds, and a light cross-onshore wind from the south at just 3 mph. That’s your best window: small but clean. It’s a beach break so it’s not going to hold much shape, but for a beginner or someone on a foamie it might be just enough. The crowds are “sometimes”, so you won’t be fighting for waves.
From the 21st onward, the energy stays moderate (around 400 again on the 21st), but the wind turns more onshore and the period drops a touch to 17 seconds. Still small, still not a standout.
For the experts, nothing here gets above 8 ft so it won’t be too heavy, but there’s no real juice. The best bet is to look at those marginal mornings between the 16th and the 20th. It’s not much, but it’s the best we’ve got. Honestly, this is one of those blanks stretches that’s more normal for this area when the swells just don’t align. Keep an eye on the forecasts because it’s bound to change, but right now, don’t get your hopes up.
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.
