Sorry, but it weirdly didn't give me a place to link. Here you go.

Here is a link that might be useful: Climate info

I am very familiar with California and growing cymbidiums in areas such as Riverside and Sacramento. If solely in terms of growing orchids, they would prefer the warmer winter in Riverside. I've known several cymbidium growers there and they bloomed cymbidiums just fine. Keys are keeping them watered enough in summer at least every other day. Feel free to ask any other questions. I lived in southern California for 40 years.

Yeah, it's not an exact one-to-one with either-- it's like the cool winter with the warmer summer. That's why I figured I would attach the temperatures and such. Yet, it's definitely not as warm as say, the Southern states. It seems like maybe warm growers would be the safest bet though?

Those temperatures are fine for most Cymbidiums.

The key to flowering most but not all Cymbidiums is average Summer Night Temperatures below about 20C

There is a cool ocean current flowing down the west coast of the USA which helps cool things down at night.

As far as winters go Cymbidiums need a cool down but most are cold tolerant down to 2C.

Average Temperatures here where they are garden plants.

Summer 17C Min Max 27C
Winter 7C Min 17C Max

Hi Arthurm! So are you saying that even the cool growers may make it under those temps? Or should I go ahead and stick to the warm growers?

Of course it all depends on your micro climate and the conditions you can provide but most Cymbidiums are very cool tolerant.

The so-called warm growers were developed to get past that 20C summer temp barrier at night to get blooms in places like Florida.

Those extreme lows are a bit of a worry especially if they occur when Your Cymbidium is in bud.

As I said above you have to look to your micro-climate. For example, are you down in a frost hollow or up higher. Some shade-cloth or a South facing brick wall will modify your micro climate.

Those average temps are for the part of Sydney, Australia close to the Pacific Ocean. Go west a bit and it is warmer in summer and cooler in winter. People still grow Cyms.

It almost never freezes (sometimes for a few early morning hours once every 10 years there is a frost, but sometimes it goes over 20 years without a frost), but I figured we would put them in pots-- so they could be moved if need be. I was more worried about the summer lows being in the upper 60s/low 70s with highs occasionally in the low 90s.

All the villages are always on hill tops-- as the wadis flood. The tells are kind of flat, so there isn't much in the way of sinking cool air like there is in other terrain.

Without having built the house yet, there isn't much way to tell about situation for microclimates-- I was just trying to figure out if it is even possible for them to make it in the climate-- warm or cool growers-- and then to see if cool growers would make it or if I need to stick to the warm ones because of the mid summer heat.

Obviously there isn't the ocean air to moderate much. The Mediterranean-- Haifa-- is about 50 miles away. Yet, the climate is pretty stable with dependable highs and lows.

You've really helped! I'm going to file away the information for future reference. :) Thank you!
