The Lowdown
G'day, Rusty here. Let me level with you. I’ve been over the numbers for Californias, and the outlook is a tough one. The next 16 days are mostly a total write-off, with hardly a wave to speak of. You’re looking at a long stretch of flatness from now straight through to Thursday the 28th of August before anything even remotely surfable shows up.
Right now, the water at Californias is 84°F, which is right around normal for the season, so no surprises there.
From Thursday the 13th of August to Thursday the 27th of August, it’s a desert. Tiny surf, mostly under 2 feet, with next to no energy behind it. The combined swell energy is often below 30, which is barely a whisper on the surface. Some days have clean or glassy winds, like Friday the 15th, but it’s only 1 foot of weak swell from the ENE with an 11-second period—absolutely no use. The good conditions are completely wasted on flat water.
The only flicker of hope comes on Friday morning, the 28th of August. We finally see a pulse of swell hitting about 4 feet from the east, with a short period of 7 seconds. The energy climbs to a moderate 165, and with a light cross-off wind from the north, the surface will be clean. It’s surfable, but it’s very ordinary. That’s your one small window, and by the afternoon, it drops straight back to flat. Don’t get your hopes up.
This kind of long flat spell isn’t unusual for the area. It happens. No standout days, no secret spots to save you. If you’re itching for a session, that Friday the 28th is your only real shot, but it’s nothing to write home about.

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.
