The Lowdown
Hey folks, Rusty here. Let me level with you straight up – this is a quiet stretch for Californias. We've got a solid 16-day window ahead, but the first five days are basically a write-off with very poor conditions for most of it. The surf doesn't start to look worthwhile until Thursday the 10th, and even then, it's more about keeping the hopes alive than lighting up the charts.
Thursday the 10th is where we get a tiny glimmer. A clean, light breeze will team up with some N swell, chest-high at 5 ft (moderate wave energy at 480), and the period stretches out to 10 seconds, adding a bit of shape. Light cross-off wind means the line-up will be smooth. It's not firing, but it's the best we get. Don't expect much consistency though.
Friday the 11th drops back down to waist-high 4 ft in the morning, then smaller in the afternoon. The energy is weak to moderate (237 dropping to 140), and while the wind stays clean, the swell is lacking punch. After that, it's a steady decline into tiny, messy surf until about the 15th, where we get another glassy morning with ankle-to-knee-high waves (2 ft) from the east. It's surfable, but just barely.
The second week is even slower. From the 13th through the 23rd, the swell is tiny and the energy is weak (well under 100 most days), with long-period groundswell trying to sneak in but failing to deliver size. The offshore winds blow hard at times – 18 to 25 mph – which keeps the surface clean but makes paddling out a serious grind. For beginners, this is not your week. For a dedicated surfer, these are the days to check the cams and maybe do something else. Honestly, with the exposure and the swell direction (mostly from E and N), the setup here looks more interesting for a kite surfer than a paddle surfer on many of these days.
The water temp is a warm 84°, absolutely normal for this time of year, so the wetsuit's not needed.
Alright, that's the story. No hidden gems here, just a long, flat spell with a single decent day on the 10th. Keep an eye on it.
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.
