Thanks
Well, I don't want to advise it if you have room inside (I would not want to be responsible if your plants don't fair well lol), but I do have a few Oncidiums outside (this one, an in spike Onc Nanboh Waltz, Onc sphacelatum and one who's name escapes me right now) - all are on sheltered porch, near a wall (which might help idk) tho sphacelatum isn't against a wall, but well sheltered. Also have a couple of Onc alliance intergenerics and Milt flavescens out side situated about the same. Except for the one who's name escapes me, which looks somewhat unhappy, the others look good.
I'm in San Jose right at the border with Los Gatos, so right up against the Santa Cruz Mountain foothills - lows are usually low 40s (sometimes warmer), tho upper 30s often enough. When forecast is for 35 or less they go into the garage to be safe. Daytime temps are usually 60s, sometimes mid to upper 50s - and of course some gorgeous days in the 70s once in a while
I think that the daytime temps are warm enough definitely helps - I wouldn't leave them out if highs were say, only 40s for an extended time.
I definitely keep them out of the rain this time of year - cold water sitting on the plants at night = rot (except for cyms which seem to be impervious to anything our weather throws at them), and definitely keep them drier when temps are getting down to maybe 37/38 (I don't allow the Oncidiums to become DRY dry, but only spray in small amounts of water til it's warmer, so they remain just lightly moist.
I just don't have space inside for all of them, at least not to give them much light, so it was leave them outside, or get rid of some
The lower temps may slow them down - definitely takes spikes forever to get to blooming
But, when they do bloom, the flowers last a long time so long as they aren't getting rained or hailed on
So, all that said, I definitely keep my eye on the weather forecast, and deal with moving quite a few plants in and out of the garage at least 2-3 times per winter
But I bet many people would be surprised at how tough some orchids actually are
