The Lowdown
Alright, grab a coffee and sit down, because this is a tough one. To be brutally honest, Japs Cove is going to be a real struggle for the next couple of weeks. This is a sheltered reef break, and it's a tricky one at the best of times, but for the vast majority of this 16-day window, it's just not going to offer anything worth paddling out for.
The first real sign of life doesn't show up until Thursday morning, the 20th of August. That morning, the wind goes glassy – a light SSE breeze at 3 mph – which is a massive positive. You'll find clean, smooth conditions. The swell is only 2 ft from the SSW with a period of 14 seconds, but the combined energy is weak (164). It's surfable, but it's very ordinary. Still, if you're desperate for a paddle and a few tiny waves, that's your best shot in the whole run.
Before that, from the 11th through the 19th, don't bother. The water temperature is notably warm, about 71°F with an anomaly of 5°F, so it's much warmer than normal for this time of year, but that's about the only highlight. The swell is tiny, inconsistent, and the wind is almost always cross or cross-onshore, making it choppy and messy. The "poor surf conditions" tag is accurate.
After that brief window on the 20th, it goes back to being poor again. The 21st and 22nd are a write-off. The 23rd and 24th offer a bit more swell energy (up to 236 and 222), but it's still small (1 ft) and the wind is ruining it.
The only other potential flicker is on Wednesday morning, the 26th of August. The combined energy jumps up to 500 – moderate energy – and the swell is 2 ft from the SSE. The wind is light cross-onshore, but the tag says "marginal surf forecast or questionable tide conditions." Still, this is the largest swell of the run, with a period of 18 seconds. That's a long period groundswell, which for a reef like Japs Cove could, in theory, produce a clean wave if the tide lines up. But it's a long way out, and the forecast is uncertain. The afternoon of the 26th gets a bigger energy reading (812) and a 3 ft swell, but the wind picks up to 15 mph cross-shore, and it's tagged as poor.
So, there you have it. If you're looking for a standout, there isn't one. The best you can hope for is a glassy, tiny wave on the morning of the 20th, and maybe an interesting but uncertain window on the 26th. For a spot that's already inconsistent, this is a long, blank run. Keep an eye on the forecasts, because it tends not to stay this poor forever.

Information about the Japs Cove Surf forecast
The above surf forecast table for Japs Cove provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Japs Cove can be found by selecting the local surf guide option on the grey menu. Our Japs Cove 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 (Japs Cove) 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 Japs Cove 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.
Japs Cove is 5 km (3 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.
