Storage conditions, temperatures

All,

Apologies for the late addition to the conversation
What temperature, in F*, do folks store their bulbs?
In Atlanta temps get into the low to mid 90s outside, and I store on my porch
In Florida they stay in the 90s all summer, but have already had a heat wave into the mid/high 90s (at which all the bulbs in the garage were brought into the house for the AC)
Leaving bulbs in the sun in Fla for very long will do them in, but what about months of high heat?

Are there detrimental effects of prolonged high heat?
Thanks in advance –

-Sara
