The Best Humidity for Cigars

The rule of thumb everyone will tell you is a 70% relative humidity (RH) and 70°F is the best cigar humidity. You will see this called the 70/70 rule. If you have one of NewAir’s Opti-Temp™ humidors, read no further!

Not all humidors have the ability to heat and cool to ensure the perfect temperature year round. If that sounds like you or you want to learn about other cigar preferences, read on.

For temperature conditions that fluctuate throughout the year, you will want to be able to track temp/humidity level to know when you have to make changes. When the temp starts to rise, you’ll want to lower the RH. The opposite is true when it starts getting colder.

Advanced tips: A higher RH will soften your cigars and can cause burn problems. A lower RH will make your cigars will feel a bit firmer. Be careful, too low of a temperature and humidity will eventually ruin your cigars, causing them to be too dry, and even cause tobacco beetles. Lastly, high end cigars and cigars with thick wrappers, like Cubans or Dominicans, say that they fare better at a lower RH, closer to around 65%. This is most likely due to the higher amount of oils in the wrapper leaf.

Due to this, some long-time cigar smokers prefer to keep their humidor as low as 65 degrees F with 67% RH. Feel free to gradually play around with the temp and RH to get the perfect burn and feel from your cigars. Try to keep your humidor below 73°F (23°C) and between 65-74% RH though.
