The Lowdown
Alright, Rusty here. Let’s be straight with you – this stretch we’re looking at for Californias is a tough one. This is a reef break that really needs the right combo, and for most of the next 16 days, that combo just isn’t happening. We’ve got a long, frustrating gap of poor surf coming up before anything even gets on the radar.
Starting now, Sunday the 23rd, we’ve got tiny 0.7ft east swell with a 9-second period – not enough to do anything. The water’s sitting at 83°, pretty average for this time of year. Monday the 24th and Tuesday the 25th look flat or close to it. A little bump shows Tuesday afternoon the 25th, with a huge 10ft east swell and a very long 16-second period – that groundswell has serious energy (5200 combined energy) but the wind is a fresh cross-off from the north. It’s clean, but this kind of long-period east swell can be tricky on a reef. That said, it’s our first real standout just because everything else is so quiet.
Then things get ugly. Wednesday the 26th delivers a solid 15ft WNW swell with a short 8-second period and gale-force cross-onshore winds. That’s a complete mess – 4070 energy but completely blown out. Thursday the 27th drops to tiny 0.7ft again with strong breeze cross-off winds. From there, we slip into a long dead zone. Friday the 28th through Monday the 1st of September is mostly flat, with cross-off winds but nothing to ride – energy stays well under 100. We’re looking at a week of nothing.
Things look like they might get interested again around Tuesday the 2nd of September. A 8ft NNE swell shows up, but it’s short-period (7 seconds) and winds are fresh cross-off. The run from the 3rd to the 6th of September is just not good for paddling. Wednesday the 3rd has a massive 21ft NNE swell with near gale winds – way too big for anyone but experts, and even then, the wind kills it. The energy is insane (8137) but the conditions are dangerous and ugly. Thursday the 4th has a 20ft west swell sliding into cross-shore near gales – again, big and messy.
Friday the 5th through Sunday the 7th of September drops down to 8ft to 2ft but stays cross-on with fresh to strong breezes. The surf is lumpy, choppy, and not worth the paddle.
The one standout in this whole mess is Tuesday afternoon, the 25th of August. That 10ft east swell with 16-second intervals and clean cross-off winds is the only window where the reef might line up. It’ll be big – expert territory for sure – but if you time it right, you might get a few. Otherwise, this is a kite-surfing kind of forecast for the most part, not a paddle-surfing one. Hang in there, and check back soon – forecasts change.

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.
