The Lowdown
Alright, Rusty here, checking in from the water’s edge. Gotta be straight with you – the next two weeks look like a tough stretch for Californias. Let’s break it down.
The first week and a half is a real flat spell. From Friday the 17th right through to Tuesday the 28th, we’re looking at a long run of tiny, weak surf. The combined wave energy is mostly in the low double digits, with the odd reading hitting 71, but that’s still very weak. Swell heights barely reach 3ft, and the periods are short, mostly between 7 and 8 seconds. The water’s a bit colder than average for this time of year at 81°, which feels a bit unusual for July. Forget about scoring – it’s a write-off for paddling. The only thing worth noting is that Wednesday the 22nd through Saturday the 25th offer some glassy to clean conditions, but with nothing to ride, it’s just a pretty picture.
Then things take a wild turn. From Tuesday the 28th, the swell starts to build, but it’s messy. We get a pulse of 6ft to 6ft on Tuesday, but it’s short-period, wind-affected junk from the NNE. The real drama kicks off Wednesday the 29th. A massive swell arrives, with the combined energy reading 6841 on Wednesday morning, then 7079 Wednesday afternoon. Heights go from 10ft to 18ft, and the period stretches to 15 seconds – that’s a very long period groundswell. This swell is way too big for this spot, especially for most of us. The wind is cross to cross-onshore, making it sloppy. Thursday the 30th is enormous – 25ft to 31ft from the WNW, with a 12-second period. The energy is off the charts at 33757. It’s spectacular to look at, but it’s way over the head for anyone but the most experienced, and even then, the wind and tide conditions are not ideal. Friday the 31st still has huge 25ft and 16ft sets, with the wind cross-shore. The standout moment comes on Saturday the 1st of August. The swell drops to a more manageable 10ft in the morning and 8ft in the afternoon, from the NW with a 12-second period. The wind turns cross-offshore, and the conditions are clean. This is the best on offer. The combined energy is still strong at 2770 and 1868. This is a solid day for experienced surfers who can handle a big, powerful reef break. The crowd profile is ‘often’, so expect company.
Overall, the only real window to get excited about is Saturday the 1st of August. Everything before that is flat, and the mid-week mega-swell is too dangerous for most. Keep an eye on the forecasts, but for now, don’t hold your breath.
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.
