The Lowdown
G’day, I’m Rusty. Let’s look at what’s coming up for Bay Street. The forecast kicks off with a real gem on Sunday afternoon, but then it’s a long, frustrating stretch of onshore junk and tiny waves for nearly two weeks. The only window of quality surf is right at the start.
The first real action hits Sunday the 6th of September in the afternoon. Bay Street is exposed to the swell, and we’re seeing a solid 3.6ft of south swell with a 14-second period. That’s a proper groundswell, long and lined up, and combined with a very light NE breeze at 3 mph, it’s going to be glassy, clean, and beautiful. The water temp is sitting at 72.1°, which is a wild 6.3° warmer than normal for this time of year – that’s very unusual, so you’ll be in for a treat. The combined energy of all swells is moderate at 536, so there’s enough push to make it fun. This is the standout of the whole window. The optimum swell direction for Bay Street is WSW, and this south swell is a bit off that, but with such clean conditions and waist-to-chest high waves, it’s still a no-brainer for beginners and intermediates. Crowds are possible as it’s sometimes busy, but with the quality, it’ll be worth it.
Monday morning the 7th is still very good – 3.3ft south swell, 12-second period, and glassy conditions with a light SSW breeze at 3 mph. The energy is still strong at 594, and it’s clean. But by Monday afternoon, the wind swings onshore from the SW at 9 mph, and the surf turns poor. After that, it’s a long grind. From Tuesday the 8th right through to Monday the 21st of September, the swell drops below 3ft almost every day, with periods mostly in the 14-to-19-second range, but the wind is nearly always onshore or cross-onshore from the SW or SSW. The wave heights get as low as 1ft or 1.3ft, and the energy drops from moderate to weak (values like 114, 169, 155). Many days are described as poor surf conditions or marginal at best. There’s a brief blip on the 14th where a 3.9ft W swell shows up, but it’s a short 7-second period and the wind is onshore, so it’s messy and not worth paddling out. From the 8th to the 21st, there’s no real recommendation – it’s a two-week stretch of mostly flat, choppy, or onshore slop.
So, bottom line: hit Bay Street on Sunday the 6th afternoon or Monday morning the 7th for the cleanest, most fun waves of the whole 16-day window. After that, you’re better off waiting for the next forecast change.

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.
