The Lowdown
Alright folks, let’s have a look at what’s on the table for the next couple of weeks.
Right off the bat, we’ve got a bit of a flat spell, but there’s some decent stuff brewing later on. The first few days are pretty average, but don’t write it off just yet. The real interest is building towards the end of the second week.
Monday the 7th sees a bit of a pulse, but it’s messy. There’s a storm risk and a strong cross-offshore wind at 19 mph. The swell is 7 ft from the north, period 9 seconds, with moderate wave energy (744). The water is a warm 84°, which is about normal for this time of year. Honestly, it’s a bit of a write-off in the morning with that lumpy cross-chop, but the afternoon cleans up slightly. Still, not a session to get excited about.
Tuesday the 8th and Wednesday the 9th are similar – cross-shore winds and that same short-period NW swell, around 6 ft to 5 ft. The energy drops from moderate (518) to weak (217) by Wednesday. Not great, not terrible, just… ordinary.
Thursday the 10th is where we start to see a glimmer. Morning is clean but small at 4 ft from the north, but the afternoon brings in a light offshore breeze from the NE at 9 mph, and the swell bumps up to 4 ft with a 9-second period. The energy is still moderate (267). It’s a better option for the first week, but it’s not a standout.
Friday the 11th and Saturday the 12th are a step back – small, dropping energy, and inconsistent. The swell drops to 2 ft by Saturday morning, with a weak 80 energy. We’re in a lull now.
Sunday the 13th is a bit of a tease. The morning is tiny, but the afternoon sees a 3 ft east swell with a 7-second period, and light offshore winds. It’s surfable, but nothing special.
We then have a long gap of poor to ordinary conditions from Monday the 14th right through to Saturday the 20th. The swell is small, the wind is mostly cross-off or offshore, but the energy is low. Nothing to pack the board for.
Now, here’s the good bit. The real standout is Californias on Monday the 21st of September. We’ve got a clean, light offshore breeze from the ENE at 6 mph, with a 3 ft swell from the east. But listen to this – the period is 15 seconds, a proper long-period groundswell. The energy jumps to 294, which is moderate but the quality will be there. This is a reef break, and that long period will wrap in nicely, offering clean, lined-up waves. It’s a good option for experienced surfers, and the crowds are often around, so expect company.
But the absolute best of the whole forecast, and I mean the one to circle on the calendar, is Tuesday the 22nd of September. The swell builds to 5 ft in the morning, peaking at 5 ft in the afternoon, from the east. The period is a massive 20 seconds – that’s very long-period groundswell. The energy is through the roof (1566 in the morning, 1626 in the afternoon). Winds are light offshore or glassy from the NE. This is excellent surf conditions for experienced surfers. The reef at Californias will handle that long period beautifully, offering steep, powerful, clean waves. It’s the best of the lot by a long shot. Keep in mind, with that size and power, it’s not for beginners.
So, to sum it up: the first week is a bit of a wash, with a small window on Thursday afternoon. The second week is mostly flat until that beautiful burst of long-period east swell hits on the 21st and 22nd. That Tuesday is the call.

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.
