The Lowdown
Alright folks, Rusty here. Let’s talk about what’s going on with our waves.
Right now, it’s pretty flat out there. We’re looking at a long stretch of tiny, weak surf for the next week and a half. Honestly, the first real chance of anything worth paddling out for doesn't show up until Tuesday the 15th of September, and even then it’s just a small pulse. We’ve got a gap of poor conditions from now until then.
The best of a very quiet period looks to be on Saturday the 19th and Sunday the 20th of September. On the 19th, we’ll see a small east swell coming in at around 3ft with a long period of 17 seconds. That kind of period is pure groundswell, which will give the waves some shape and push, especially on a reef setup. The wind will be a cross-offshore breeze, keeping things clean. The combined energy will be moderate. It’s not huge, but it’s the most interesting we’ve seen in a while. The following morning, the 20th, the swell bumps up to 6ft from the east with a 14-second period. That’s a bit more size, but the wind is forecast to be a strong near-gale cross-offshore, which will make things pretty gnarly and challenging. That’s really one for experienced surfers only.
Californias is the only break we’ve got data on. It’s a fairly consistent reef break that handles an east swell well, but it’s an advanced spot so don’t get caught out if you’re not ready for it.
Water temps are sitting around 84°, which is about average for this time of year, so nothing unusual to worry about there.
The long-range stuff around Monday the 21st of September shows a bigger, shorter-period NNW swell, but the wind is looking messy and onshore. It might be more of a kite-surfing day than a proper paddle session. After that, it’s back to small, weak, and windy conditions for the rest of the forecast window.
So, if you’re keen, circle Saturday the 19th of September for the most promising window. It won’t be epic, but it’s the best we’ve got on the table.
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.
