    the thing is, sandtiger, that there is a ton of info on the web, but much of it is just a guideline, not a rule. i've seen people list orchids as their winter min at 65 and summer max at 85, and they handle my 45 winter and my 95 summer just fine, with occasional spikes both directions for a week at a time. they probably would do better in their ideal range, but they do just fine. i've left my mokara out all year before, and it did ok, stopped growing in the cold, and blasted a few buds in the heat, but survived to bloom for many years since. you should avoid anything that will have obvious problems, like odontoglossums, and himalayan vandas, but the best thing to do is research FIRST where the orchid (or its parants) come form, and check the temps there. also, note that many hybrids have both cool and hot tolerant parents... so you get the best of both. but really, it is trial and error. it's also good to locate a few orchidists in your area, who can steer you towards what is safe for you sp you don't make expensive mistakes. maybe there are people on here from your area and they will chime in with suggestions? but seriously, most of the vandas and cattleyas are more tropical plants than anything else, so don't panic. and if you kill a few, it happens.

    and just to say so that you know i practice what i preach - i've bought several 'test orchids' this year, a selection of oncidium related plants, to see which can handle my grow area, which is outside 3/4 of the year or more, and crowded into a south and a west window for winter. last year some oncidium and miltassia did ok, so this year i'm trying a few more, with more brassia and odontoglossum in the mix. i've seen several that are supposed to be 'cool tolerant' and if they survive the summer, we're gonna find out just how cool tolerant they really are!

    Leave them be...that's my opinion anyway. Where we are, I can have temperature differences of fifty degrees in a single day. It's not too hot for very long. Its not so cold for very long either. I've had more trouble running the plants in and out than I have just leaving them where they were.
