The Lowdown
G’day, Rusty here. I’ll be straight up – this stretch is a real bummer. We’re looking at Bay Street over the next couple of weeks, and the surf is barely a whisper. For the first few days, from Saturday the 12th through the end of the week, it’s mostly flat or barely moving. The swell hangs around 1 to 2 feet from the SW, with periods that are long enough to suggest some energy deep down, but it’s all cross-onshore wind or onshore, which just messes it up. The combined swell energy is weak to moderate (161), so you’re not getting any real push. It’s not worth paddling out for.
The water’s running 74°, which is much warmer than normal for this time of year – that’s a 8° anomaly. Something’s definitely off with the seasons here.
There’s a real gap of nothing happening. From Saturday the 12th right through to Wednesday the 16th, it’s flat and messy. Even the days that get a “marginal” tag – like Wednesday the 16th morning – only have a 2-foot swell, and the wind is still cross-onshore. The combined energy climbs a bit to 212 (moderate), but it’s not enough to make it worthwhile.
As we move into the second week, the surf stays stubbornly small. The mornings of Thursday the 17th and Friday the 18th show a bit of promise with 2 to 2-foot swell and some offshore wind (SSW, 6–9 mph, so glassy), and the periods stretch out to 16–19 seconds, which is proper long-period groundswell. The combined energy hits 293 (moderate). The waves might hold some shape, but the size is just too small for any real ride.
The best of a bad bunch is probably Saturday the 19th morning. You’ve got 2-foot SW swell, 18-second period, and a very light offshore wind (SSW, 3 mph) – that’s about as clean as it gets. The water’s still glassy, and the energy is 293 (moderate). If you’re a beginner, this is your window, but don’t expect much push.
After that, the trend is down. From Monday the 21st to the end of the period, the swell hovers around 2 to 3 feet, with increasing onshore winds. The combined energy stays moderate (up to 381), but the quality never lifts. It’s essentially a 16-day dead spell for any decent paddle surfing. If you’ve got a kite, the small chop and consistent cross-offshore breeze might be your thing, but for a traditional surf, it’s a hard pass.
Keep an eye on the charts, but for now, grab a coffee and wait.
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.
