What Humidity Should a Cigar Humidor Be?
Choose a stable RH that protects the wrapper, preserves aroma, and still allows an even burn.
Quick Verdict
Keep stored cigars between 65% and 72% relative humidity, with 69% RH as the safest all-purpose starting point. Stability matters more than chasing a perfect single reading. Choose 65% for a slightly drier profile, and reserve 72% for dry rooms or drafty wooden humidors—not tightly sealed acrylic storage.
Relative humidity, or RH, describes how much moisture the air holds at its current temperature. In a humidor, it influences wrapper flexibility, flavor preservation, draw, and combustion. Too little moisture can make cigars brittle and fast-burning; too much can produce a tight draw, poor combustion, swelling, or mold risk.
The Practical Humidor RH Guide
| Target | Best use | What to know |
|---|---|---|
| 65% RH | Drier profile, easier burn, long-term aging | Check delicate wrappers for dryness. |
| 69% RH | Best default for most wood, acrylic, travel, and sealed humidors | Start here when uncertain. |
| 72% RH | Dry climates or drafty wooden humidors | Avoid using extra humidity to hide a damaged seal. |
| 84% RH | Seasoning an empty wooden humidor only | Never store cigars at this level. |
This 65%–72% storage range and the 69% default follow Boveda’s current cigar guidance. Preferences vary, so change the target gradually and judge the cigar’s condition and burn—not only the display.
Match Humidity to the Humidor
Begin at 69% in a seasoned desktop box. An airtight acrylic humidor or polymer travel case loses little moisture, making 69% a sensible ceiling as well as a target. For an electric cabinet, use its manufacturer’s setpoint and allow every shelf to stabilize before adjusting it.
Construction still matters. A portable cedar humidor exchanges moisture with its wood, while a 100-cigar acrylic and cedar model retains humidity differently. A glass-top desktop humidor also deserves closer observation around its lid and window seals.
Read the Hygrometer Correctly
Verify the Instrument
Calibrate or test the hygrometer according to its instructions. An attractive display is useless if it reads several points high or low.
Measure Near the Cigars
Place the sensor where air can circulate at cigar level, away from direct contact with a humidifier or wet pack.
Watch the Trend
Opening the lid causes temporary movement. Wait for the closed humidor to settle, then assess the multi-day pattern rather than one moment.
Too Dry or Too Humid?
Likely Too Dry
RH stays below 65%, wrappers feel fragile, or cigars burn unusually quickly. Check the seal, depleted humidity control, room conditions, and hygrometer accuracy.
Likely Too Humid
RH remains above 72%, cigars feel swollen, draws tighten, or relighting becomes frequent. Remove excess humidification and inspect carefully for mold.
Correct slowly. Do not spray cigars, wipe cedar, or add an open dish of water. Replace or reduce the appropriate humidity control, close the humidor, and reassess the trend after it has stabilized.
Common Humidity Mistakes
- Treating 70/70 as an absolute rule
- Mixing different RH packets
- Using 84% seasoning packs with cigars
- Reacting to every short-term fluctuation
- Ignoring a leaking or warped seal
- Trusting an untested hygrometer
Frequently Asked Questions
Is 70% humidity good for cigars?
Yes. It sits within the practical 65%–72% range, although many collectors prefer the slightly drier 69% setting.
Is 60% humidity too low for a humidor?
For routine premium-cigar storage, 60% is below the usual range and may gradually dry wrappers and accelerate the burn.
Is 75% humidity too high for cigars?
Yes. Prolonged storage at 75% can cause swelling, difficult draws, poor burning, and a greater risk of mold.
Should I use 65%, 69%, or 72% humidity packs?
Choose 69% as the general default, 65% for a drier profile, or 72% for a dry environment or drafty wooden box.
Why does humidor humidity drop after opening?
Room air enters when the lid opens, causing a temporary change. Close the humidor and judge the stabilized trend.
Can I mix two different humidity levels?
No. Different RH packs work against each other, reducing efficiency and making humidity control less predictable.
