I've shipped leos when it was 104 degrees and heard of one person doing it at over 110. If its going to be at any point above 85 you'll want a ice pack and with excessive temps you want a oversize ice pack and very good insulation. I don't recommand shipping when its in the high 90s or more in my case unless I wanted to wait weeks on end shipping in ideal temps wasn't an option. I never lost one except when the receiver didn't live in a area where DHL shipped by 1030 am and the temps where only in the 80 at both locations.
