The Lowdown
Alright, Rusty here. Let’s have a look at what’s on offer for TCs.
Honestly, the whole 16-day window looks pretty grim. We’re looking at a long stretch of small, weak swell and average to poor conditions. For the first week and a half, the surf is barely a whisper. The swell is tiny, mostly between 1.0 ft and 2 ft, with a period that’s all over the place, from a short 12 seconds to a drawn-out 19 seconds. The wind is a constant problem, always cross-onshore or cross-shore, never giving us a clean face. The combined energy is mostly weak to moderate, ranging from 115 to 259 (moderate), except for a few afternoons where it pushes into the mid-300s (moderate). But with the wind and small size, it’s just messy.
The first real glimmer of hope doesn’t come until the very end of the month. On Saturday, August 29th, the afternoon shows a bit of a pulse. We’ve got a 3 ft swell from the SSW, with a 16-second period and combined energy hitting 454 (moderate). That’s the most energy we’ve seen all forecast. The swell direction is right on the money for TCs, but the wind is still a cross-shore from the W at 12 mph, keeping it from being truly clean. It’s a good energy signal, but not a classic day.
The standout, if you can call it that, is the morning of Saturday, August 29th. The swell is 2 ft from the SSW, period 17 seconds, and combined energy is 325 (moderate). The wind is a light cross-on from the SW at just 3 mph – that’s a slight air, almost glassy. That’s the closest we get to clean conditions. The water temperature is about average for this time of year, so no surprises there.
The later morning on Sunday, August 30th is another similar look: 3 ft from the SSW, 15 seconds, with a light cross-on from the S at 3 mph. It’s a similar story – small, but with that rare light wind.
For a reef break rated for advanced surfers, these tiny waves won’t be offering much. Don’t expect a crowd; with this forecast, it’ll be quiet. The only real highlight is the 29th morning – that’s your best bet for a clean, small-wave session, but it’s not going to set the world on fire. The rest of the window is a write-off.
Rusty.

Information about the TCs Surf forecast
The above surf forecast table for TCs provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at TCs can be found by selecting the local surf guide option on the grey menu. Our TCs 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 (TCs) 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 TCs 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.
TCs is 7 km (4 miles) from Rancho Palos Verdes. If you plan a vacation in Los Angeles County, look for hotels and other accommodation in Rancho Palos Verdes. Rancho Palos Verdes has rooms for a wide range of budgets as well as car hire and transport links.
