whats most harmful during the Hot summer months is the RH spikes. Temps really aren't an issue (70-80). I know not everyone can run an AC all day long (neither can i) but you have to remember where most cigars are made and stored before they get in your hands (typical hot climates ).

My go to summer plan during the hot summer months is more RH control and i do that by not using my HF beads at all and use almost dry Kitty litter in my cooler instead. NYC summers are as humid as Barbara Walters thighs while watching a Matthew Mcconaughey movie so the dry KL soaks up all the extra humidity. Been doing this for Years. never had an issue.
