The Lowdown
Alright, let’s break it down. Wednesday morning is the only real chance in this 16-day window, and I’m not gonna lie—it’s a tough run. There’s a big gap from Thursday afternoon all the way through the second week, with barely a morning that’s worth paddling out for.
The one standout is Wednesday, the 3rd of September, at Californias. This reef break is getting a 1.7m east swell, 10-second period, with moderate combined energy at 644. Water temp is 29°, right on average for the season. That morning, we’ve got a light NNE cross-off breeze at 15 km/h, keeping the surface clean. The wave’s got some push, but at 1.7m, it’s more for advanced surfers—not a beginner day. The break is fairly consistent, but crowds are often a problem, so expect a lineup. The swell direction is east, which is okay but not perfect for the optimum north direction.
Thursday morning the 3rd goes downhill quick with a 25 km/h NW wind and a 1.6m swell that’s already messy. Friday and Saturday are straight onshore junk. Sunday morning the 6th has a clean 1.5m north swell, 10-second period, with a cross-off NE breeze at 20 km/h—that’s surfable, but the combined energy is moderate (517) and the report says “marginal.” It’s the next best thing, but it’s not a standout.
From Monday the 7th onward, it’s a desert. The swell stays small, the wind is often strong or cross-off, and the scores are all zeros or ones. The 11th of September has a brief moment of clean, light offshore easterly wind at 5 km/h, but the swell is only 1.1m with an 8-second period—weak. The combined energy is just 183. That’s a desperate paddle.
Straight up: Wednesday morning the 3rd is your only real shot. After that, it’s a long, dry spell. The second week is tiny—most swells under 0.8m, clean but completely lifeless. Not much to work with.

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.
