A-      Cigars come from a tropical environment so the answer is NO.  Pardon the joke but a cigar store should remain room temperature 70 degrees or at least the humidor should.  The reason is not just that if it is warmer than 70 it completely changes the RH (relative Humidity).  The main problem here is tobacco beetles.  They are in most every cigar but lie dormant and pose no problem. If they come alive due to increased temperatures, however, your cigars will resemble Swiss cheese.  The really scary part is that small studies have been done that seem to show that beetles may come alive years after the cigars were exposed to high temperatures.  So be VERY careful taking cigars from a warm store and adding them to your humidor at home. Also, when a cigar beetle comes alive you may not see the beetle but you will see a noticeable perfectly round hole in the cigar.  A good cigar store checks all cigars before selling them to the consumer.
