The Lowdown
Alright folks, Rusty here. Gotta be straight with you – this stretch is a real bummer for the lineup. We’re looking at a 16-day window, and honestly, there’s nothing worth paddling out for. The first few days might tease you with a little knee-high bump, but it’s all poor conditions and tiny energy. Let’s run through it.
Starting off Wednesday the 12th, we’ve got a tiny 1ft swell from the ENE at 11 seconds pushing into Californias. The combined energy is weak, just 40, and with a risk of thunderstorms and a cross-onshore breeze, it’s messy. The water’s sitting at 84°F, which is about average for this time of year, but that’s the only thing that’s normal. Thursday the 13th, the swell drops even more – 2ft from the north with a short 8-second period, and while it’s glassy in the morning, the energy is pathetic at 28. It’s not surfable.
Friday the 14th through the weekend stays flat, with nothing over 1ft and winds turning onshore or cross-off. The combined energy barely cracks 30. By Monday the 17th through the 19th, we’re looking at 1ft or less, and the wind is howling cross-off at 12-16 mph, but the swell is too weak to do anything with. The energy drops to 19, then 9. It’s a dead zone.
There’s a gap of several days with no real surf. From the 20th onward, it’s all flat. A few little 0.7ft pulses show up on the 26th and 27th, with a period of 11 seconds, but the energy is still a measly 9. Winds are cross-off and moderate. For a reef break like Californias, that’s just not enough push. The whole forecast is a dud – no standouts, nothing to get excited about. For a spot that’s fairly consistent, this blank run is a bit of a surprise, but it happens. Forecasts can change. For now, leave the board in the shed.
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.
