The Lowdown
Alright, Rusty here. Let’s look at what we’ve got coming down the line for Californias.
It’s a bit of a frustrating start, to be honest. There’s a lot of week ahead with messy conditions. We kick things off on Thursday the 27th, but that afternoon is a write-off. We’ve got a 8ft swell from the west pushing through a lot of energy (1321), but the wind is a howling cross-shore and there are storms around. It’s not a surfer’s ocean right now.
We then hit a proper dry spell. From Friday the 28th all the way through to Monday the 1st of September, the surf is either tiny, non-existent, or getting smashed by gale-force winds. You’re looking at a solid four to five days where you wouldn’t bother paddling out. There’s a brief moment on Sunday the 30th where the wind goes offshore from the east, but there’s no swell to work with, so it’s flat.
Things start to rumble back to life around Tuesday the 2nd, but the wind is onshore or cross-onshore, keeping everything choppy and ugly. The energy is moderate (334 to 958), but the quality just isn’t there. It’s not until Saturday the 5th of September that we see a glimmer. The swell drops a bit to 5ft from the north, swinging around with a long period of 11 seconds. That’s a nice groundswell, but the wind is cross-shore, keeping it a bit bumpy. It’s still just marginal.
Now, the true standout of the whole outlook is Sunday the 6th of September. That afternoon, the wind swings offshore from the east, right into the optimum north direction for this reef. The swell jumps to a clean 7ft from the north, packing a solid 686 units of energy. The wind is just a light breeze, making it clean. This is the pick of the fortnight. It’s a proper groundswell with a bit of period behind it, and it’s going to line up nicely on the reef. This will be for the experienced crew, as it’s a solid size.
The following week is more of the same, with periods of clean wind but mostly cross or cross-onshore conditions. Monday the 7th starts with a 7ft NNW swell and light wind, but it gets wrecked by the afternoon. Thursday the 10th and Friday the 11th of September look promising as well, with a dropping 5ft to 6ft NNW swell and light offshore winds from the north-east. Those will be clean, fun waves, but nothing compared to the punch we get on the 6th.
Stay patient, fellas. The 6th of September is your day.
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.
