The air temperature was some twenty degrees Fahrenheit (about 10 Celsius degrees) higher than the closest vaporization point, but the tests were affected.



Something similar, I have a stove that use those slim butane canisters, and even in ambient temperature in the high 20's, after some use the canister would get cool enough to unable to supply a strong flame,
