Another idea if you're concerned, is every transition from inside to outside either needs to take advantage of temperature fluctiuatons--in the winter, you find a few days of very mild nights, and move them out then. You could either wait until you get the 90 degree highs, and move them then, or you could try taking them outside for a few hours earlier in the day, bringing them in for the heat of the day. Leave them out a bit longer in increments, giving them a few days getting used to gradually hotter temps. e.g., take them out tomorrow from 7 am till 10 am, for a few days, then from 7 am till noon, etc or whenever it gets to 85 degrees, then 90 degrees, etc.
