The Lowdown
G’day, Rusty here. Gotta be straight with you – it’s a rough stretch ahead for Californias. We’re looking at a solid 16-day window, but honestly, there’s barely a ripple worth paddling for. The surf’s tiny and messy for the first week, then it flat-out dies for a few days before some wind swell tries to show up, but the wind ruins it. Let’s run through it.
Starting now, Thursday the 13th of August, we’ve got nothing doing. Tiny waves around 2 ft from the north with a short 8-second period – that’s weak, barely breaking. The combined energy is a measly 28, so there’s no push. Thursday afternoon goes glassy with the same size, but it’s still poor surf.
Friday the 14th is worse, dropping to 1 ft and then 1.0 ft. Saturday and Sunday the 15th and 16th stay in the 1.0 ft range, with a bit more direction from the ENE and a period lifting to 10–11 seconds, but the energy is still in the low 20s. There’s some glassy conditions on Saturday morning, which is nice, but you need something to ride. This is flat spell territory.
Monday the 17th through to Wednesday the 19th of August sees tiny, poor surf with offshore winds, but the swell is barely there – still 1.0 ft to 2 ft and short period. Not worth suiting up.
Then, Thursday the 20th of August, we get a little bump. Morning shows 3 ft from the east with a period of 9 seconds, and the combined energy jumps to 106 – that’s moderate energy now. But it’s still poor surf with a fresh cross-offshore wind from the SE at 19 mph. It’s clean-ish, but the size is tiny and the direction isn’t right for Californias, which wants swell from the north. This is the closest thing to a highlight, and it’s a weak one.
After that, it’s a wasteland. Friday the 21st drops to 0.3 ft, and from Saturday the 22nd through to Tuesday the 25th of August, it’s either tiny or flat – literally zero swell on the 24th and 25th, with gale-force winds up to 53 mph. Forget it.
Wednesday the 26th to Friday the 28th of August, some 2 ft to 3 ft east swell returns with periods around 9–10 seconds, and energy hits 129 on the 27th morning, but it’s totally blown out by severe gale cross-onshore and onshore winds. Rubbish.
Best on offer? It’s bleak, but if you’re desperate, Thursday the 20th of August morning is your only shot – 3 ft east swell, 9-second period, moderate energy (106), and reasonably clean despite the cross-offshore wind. Don’t expect much.
Bottom line: a long, flat run. Stay patient, check back – forecasts can 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.
