The Lowdown
Alright, let’s talk about Californias. It’s a reef break, advanced only, and the water’s sitting at about 86°F—that’s a touch warmer than usual for this time of year, maybe a degree or so above average.
First week is a total bust. From Wednesday, July 29th, all the way through to the start of August, there’s flatness. Glassy, calm, but no waves to speak of. A solid six or seven days of nothing.
Then things fire up. On Tuesday, August 4th, we get a proper east swell, 4ft, period 18 seconds—that’s groundswell. Energy is moderate (1044), and the wind is cross-offshore from the north, keeping it clean. That’s your best bet. Tuesday afternoon it’s 5ft, same period, energy up to 1388, still clean. The swell direction is east, the optimum here is north, but the quality of the wave and the wind make it very good.
Wednesday, August 5th, goes bigger. Morning has 6ft east swell, 19 seconds, energy 2528—strong. Afternoon hits 8ft, same direction and period, energy 4317. That’s very strong. Wind stays cross-offshore, so it’s clean, but at 8ft on a reef, that’s expert territory. Not for beginners.
Thursday, August 6th, is still big but the wind turns cross-shore from the northwest. Morning has 8ft, 18 seconds, energy 4605, but it’s getting a bit lumpy. Afternoon drops to 6ft with a 35 km/h cross-shore wind—messy.
Then it falls apart. Friday, August 7th, is gale-force west winds, 45–50 mph, completely blown out. That mess continues through the weekend. Monday, August 10th, has some small east swell but the wind is still cross-shore and lumpy.
There’s a small window on Wednesday, August 12th: afternoon sees 4ft east swell, 11 seconds, with a gentle offshore wind from the east-northeast. Energy is 307 (moderate). The forecast says “expect good surf conditions.” That’s a clean little session, but it’s small.
The standout is Tuesday, August 4th, with clean east swell. Wednesday, August 5th, is the big-wave day for experts only. Crowds at Californias are “often,” so expect company on the good days.
Signing off, 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.
