The Lowdown
Alright, let’s talk about Bay Street. Honestly, looking at the whole 16-day window, it’s not firing. There’s a whole lot of nothing to start. We’ve got a solid gap of poor conditions right through until the morning of Sunday the 23rd of August, and even then it’s only marginal.
The first real sniff of anything worth paddling out for doesn’t come until Sunday the 23rd. The swell is tiny at 1ft out of the SW with a very long period of 19 seconds, but the combined energy is still only moderate at 209. The wind is light and offshore from the SW, so it’d be clean, but the size is really for a longboard or a foamie. That long-period groundswell will lean towards a bit of a lazy line-up on a beach setup, but with the offshore breeze it should hold up. It’s a marginal call at best though.
The next potential highlight pops up on Tuesday morning, the 25th of August. Still small, 2ft from the SW, but the swell period drops to a more workable 16 seconds. The combined energy jumps up to 342, still moderate, but better. Wind is offshore from the SSW at a light 6 mph, so clean conditions are on the cards. Again, it’s marginal—don’t expect to get your head wet.
Looking further out, Saturday the 29th of August morning shows a slight bump. The swell height nudges up to 3ft from the SSW, but the period drops to 17 seconds with a cross-onshore wind from the S at 6 mph. The combined energy is a solid 350, but that onshore bit will put a wrinkle on the face. Not great, but it’s the biggest swell we see in the whole stretch.
Honestly, if you’re desperate, the best of a bad bunch looks like Sunday the 30th of August morning. Swell at 3ft from the SSW, period 15 seconds, and finally a clean offshore wind from the SSW at 6 mph. Combined energy is 360. It’s still marginal, a long way off, but on paper, it’s the standout moment.
Water temp is a warm 70°F, which is much warmer than usual for the time of year, so you won’t need a thick suit. Bay Street is a beginner-friendly wave and it’s fairly consistent, but crowds can be a problem here sometimes. The main issue is that the swell is almost constantly onshore or cross-onshore for much of the period. When the wind does swing offshore, the swell is just tiny. This stretch is looking pretty slim, but forecasts can change, so keep an eye on it.

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.
