The Lowdown
Alright folks, Rusty here. Let’s get into it.
The next 16 days start off with a quick little pulse on Thursday the 10th, but honestly, after that, it’s a long, flat spell that’s tough to get excited about. We’ll see a decent morning and afternoon session, then a real dry run from Friday through most of the following week. The second week has some size, but it’s going to be a wild, windy mess for most of it.
The standout is Thursday, September 10th at Californias. The reef will be handling a clean 5ft to 5ft swell from the north with a 9-second period, and the combined energy is moderate (306-397). The cross-offshore wind from the north-northeast is what you want – it’ll keep the faces clean and lined up. This is the best on offer, and it’s not a day to sleep in. The water temp is about average for this time of year.
Friday the 11th drops off quick. Swell drops to 4ft in the morning and 3ft in the afternoon, with a risk of thunderstorms. The conditions are surfable but ordinary. The energy is weak (130-198). It’s a step down.
From Saturday the 12th through to Tuesday the 15th, it’s grim. Heights are down to 0.7ft to 2ft, period is short or long with no energy, and the ratings are poor. The wind stays light, but there’s just not enough swell to do anything with. There’s a glassy moment Tuesday afternoon with 2ft, but it’s weak and ordinary.
A brief window shows up on Thursday the 17th with a clean 2ft to 2ft from the east, light offshore wind, and weak energy (96-104). It’s just enough for a small-wave log, but nothing to write home about. Friday the 18th keeps the offshore wind but the swell is tiny.
The weekend of the 20th and 21st gets windy. Saturday the 20th has a cross-offshore breeze hitting 19-22 mph with a 3ft swell – messy. Sunday the 21st has a near-gale blowing 31-34 mph and a 6ft north swell, but the wind is just too strong. This setup is more interesting for kite surfing than paddle surfing.
Then things get wild. Monday the 22nd has a gale-force cross-onshore wind at 40 mph, an 8ft east swell with a very long 16-second period, and massive energy (4017). That’s expert-only territory, and it’s completely blown out. For a reef break like Californias, that long-period east swell could be interesting, but the wind is a total dealbreaker. Tuesday the 23rd is still messy with a fresh cross-shore wind and 7ft swell.
The final days, Wednesday the 24th and Thursday the 25th, drop back to small, clean, and utterly ordinary surf. The window closes with a whimper.
So, your best bet is Thursday the 10th. Get out early. After that, it’s a long wait for something that never quite comes together.
Rusty.

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.
