The Lowdown
Alright, Rusty here again. Let’s break this down.
It’s a slow start. We’ve got a long, quiet spell before anything decent comes through. Plenty of small, sloppy surf for the first several days.
The spot is Topaz Street, a beach and jetty break that’s open to the west. The water temperature is a warm 73°, which is running about 8° above the long-term average for this time of year. Unseasonably warm.
Monday the 14th and Tuesday the 15th are basically flat. We’ve got 1ft waves from the SW with a long 18-second period, but the wind is either cross or cross-off and the combined energy is weak, under 100 (96) on Monday morning. Not a show.
Wednesday the 16th brings 2ft from the SSW with a 17-second period, but a light cross-shore wind keeps the surface lumpy. The energy ticks up to 217 (moderate), but it’s still not worth rushing out for.
Thursday the 17th is the same story – 2ft to 2ft, light cross-onshore wind, and that long period. It’s not clean.
Friday the 18th morning is the first real glimmer. We finally get a light cross-shore breeze, clean surface, with 2ft of 19-second SW groundswell. The energy sits at 274. It’s small, but clean and lined up on the jetty. That’s the best we’ve seen so far.
Saturday the 19th and the days following are mostly onshore in the afternoons, killing the fun.
Here’s the good stuff: Sunday the 20th morning. Winds go light cross-offshore from the SSE, giving us glassy conditions. The swell is 2ft from the SW at 18 seconds, with energy at 318. That’s a clean, small morning worth paddling for.
Monday the 21st morning is the pick of the bunch. Winds are cross-offshore from the SE, it’s clean, and the swell pushes up to 3ft from the SW, still with a 17-second period. The combined energy hits 396 – solid moderate energy. That’s your best session right there.
After that, it drops off. Tuesday the 22nd is back to onshore winds and fading swell. The rest of the week through to the 28th is a mix of onshore wind, poor conditions, and small weak swells. Not good.
The final chance is Tuesday the 29th morning. We get another clean, cross-offshore breeze from the SE. Swell is 2ft from the SW, 14-second period, with energy at 281. A nice, clean finish to the outlook.
So, to keep it simple: the first week or so is a slog. Your two real windows are Sunday the 20th morning and Monday the 21st morning. Monday the 21st has the best size at 3ft, clean winds, and solid energy. That’s the one to aim for.
With 3ft waves, it’s fine for beginners and intermediates alike. The long-period swell makes for cleaner, longer rides on the jetty, but expect longer waits between sets.
That’s the story. Keep your eye on the 21st.
Rusty.

Information about the Topaz Street Surf forecast
The above surf forecast table for Topaz Street provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Topaz Street can be found by selecting the local surf guide option on the grey menu. Our Topaz 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 (Topaz 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 Topaz 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.
Topaz Street is 2 km (1 miles) from Redondo Beach. If you plan a vacation in Los Angeles County, look for hotels and other accommodation in Redondo Beach. Redondo Beach has rooms for a wide range of budgets as well as car hire and transport links.
