The Lowdown
Alright folks, Rusty here. Let’s be straight with you – this 16-day window for Californias is a tough one to get excited about. We’re looking at a long stretch of nothing much, so don’t get your hopes up too early.
The pattern starts out pretty grim. The first few days, from Tuesday the 8th through to the end of the week, are a write-off. We’ve got a moderate wave energy (514) on Tuesday morning with a 6ft swell from the NNW, but it’s blown out by a 19 mph cross-off wind. The conditions are just poor. It stays ugly right through Wednesday and Thursday, with the wind sticking around. Even though Thursday morning shows a bump in energy (751), the surf is still only marginal with those wind conditions.
The first real standout, and honestly the only one worth circling on the calendar, is the 23rd of September. That’s a week and a half away, so it’s a long-range promise, but it looks like the best we’ve got. On Wednesday morning, the 23rd, we’ve got a solid 5ft swell from the SW, clean conditions with a gentle offshore breeze, and the energy is moderate (375). The forecast says "expect good surf conditions," and with that light E wind, it’s going to be clean. The swell direction is from the SW, which is a solid match for this reef setup. It’s a fairly consistent break, so if this holds, it’ll be the pick of the period. The afternoon also looks good, with a similar 5ft swell and clean conditions.
Before that, there’s a big gap. From the 8th right through to the 22nd, it’s a desert. We get a tiny glimmer on the 22nd with a 4ft, long-period 14-second swell from the E, and the energy is strong (654), but the forecast calls it marginal. That long period (over 15 seconds is very long, so 14 seconds is getting there) can mean the waves break a bit straight at this reef, and the conditions are only "cross-off" with a moderate breeze, so it’s not a clean guarantee.
The water is sitting at 84°F, which is pretty much average for this time of year, so no worries there.
In short, don’t waste your time for the next week and a half. Mark the 23rd of September. That’s your window. It’s a long way off, but it’s the only one that’s got the combo of size, direction, and clean wind. Hope it firms up.

Information about the Californias Surf forecast
The above surf forecast table for Californias provides essential information for determining whether the surfing conditions will be good over the next 16 days. A general guide to surfing at Californias can be found by selecting the local surf guide option on the grey menu. Our Californias 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 (Californias) 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 Californias 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.
Californias is 5 km (3 miles) from Misato. If you plan a holiday in Okinawa, look for hotels and other accommodation in Misato. Misato has rooms for a wide range of budgets as well as car hire and transport links.
