Your Hygrometer Is Measuring the Air, Not Your Cigar
Your humidor reads 69% RH. Everything looks perfect.
But there is one important detail many cigar owners misunderstand: your hygrometer is not measuring your cigars.
It is measuring the humidity of the air surrounding them. A hygrometer indicates atmospheric moisture conditions, while the tobacco itself has its own moisture content. The two influence each other, but they are not the same measurement.
What You'll Learn
- What a hygrometer actually measures.
- Why 69% RH does not mean your cigar is "69% humid."
- How cigars exchange moisture with humidor air.
- Why temperature changes the meaning of RH.
- Why patience and stability matter more than constantly adjusting your humidor.
What Does 69% RH Actually Mean?
Relative humidity describes moisture in the air relative to how much water vapor that air could hold at the same temperature.
It does not mean that 69% of your cigar is water. It does not directly tell you how many grams of moisture are inside the wrapper, binder, or filler either.
Your hygrometer is essentially reporting on the cigar's environment.
Your Cigar Responds to That Environment
Tobacco is hygroscopic, meaning it exchanges moisture with its surroundings.
Place relatively dry tobacco into a properly maintained humidor and it can gradually absorb moisture. Place wetter tobacco into a drier environment and moisture can move in the opposite direction.
Eventually, given sufficient time and stable conditions, the tobacco and surrounding environment move toward a moisture equilibrium.
This is why the hygrometer is useful. It does not directly tell you the cigar's internal moisture content, but it helps you understand the environment driving that moisture exchange.
Air Can Change Faster Than Tobacco
This distinction becomes particularly important when a humidor changes conditions.
Imagine opening your humidor for several minutes. The air inside is exchanged with room air, and the hygrometer reading may move relatively quickly.
That does not mean every cigar instantly experienced the same moisture change.
Moisture must move through tobacco over time. A short-lived change in the surrounding air and a sustained change in the cigar itself are different events.
Why Chasing Every Hygrometer Movement Can Backfire
You open the humidor and RH falls. You add humidity.
Later, the reading climbs. You remove humidity.
Then it falls again.
This constant correction can turn a stable storage system into an unstable one. Small temporary changes can occur after opening the humidor, adding cigars, changing room temperature, or moving the box.
Watch the trend, not every momentary number.
Temperature Changes the RH Reading Too
Relative humidity is temperature-dependent. That makes temperature particularly relevant when interpreting a hygrometer.
A change in temperature can change relative humidity even when the amount of water vapor present has not changed proportionally. Professional humidity calibration therefore controls temperature as part of the measurement environment.
This matters in Dubai, where cigars can move between intense outdoor heat and strongly air-conditioned interiors.
One Humidor Can Have Microclimates
Large humidors and cabinets may not have perfectly identical conditions at every point.
The area beside a humidification source may behave differently from a distant shelf. Air circulation, cigar density, shelves, drawers, and sensor placement can all influence what a hygrometer reports.
A reading of 68% in one location does not prove that every centimeter of a large cabinet is simultaneously at exactly 68%.
So How Do You Know Whether Your Cigars Are Properly Stored?
Use the hygrometer as one piece of evidence rather than the entire diagnosis.
- Monitor temperature and RH together.
- Look for stable trends over time.
- Use a properly functioning, calibrated sensor.
- Observe wrapper condition and flexibility.
- Pay attention to draw and combustion.
- Avoid repeatedly correcting minor short-term fluctuations.
- Give newly introduced cigars time to acclimate.
The goal is not to make the display look perfect every minute. The goal is to create an environment in which premium tobacco can remain consistently conditioned.
Why This Matters More in Dubai
Dubai introduces unusually large environmental contrasts. A cigar may move from an air-conditioned residence to outdoor summer heat, into a vehicle, and back into another cooled building.
That makes environmental stability particularly valuable.

Final Thoughts
Your hygrometer is extremely useful. Just understand what it is actually telling you.
It measures the environment around your cigars, not the moisture hidden inside every leaf. Your tobacco then responds to that environment gradually.
Once you understand that distinction, cigar storage becomes less about obsessing over a number and more about what truly matters: temperature, humidity, time, and stability.
Frequently Asked Questions
Does a hygrometer measure the moisture inside a cigar?
No. A humidor hygrometer measures humidity in the surrounding air. It does not directly measure the cigar's internal moisture content.
Does 70% RH mean my cigar contains 70% moisture?
No. Relative humidity describes the surrounding air and should not be confused with the percentage of water contained in the tobacco.
Why does my hygrometer change when I open the humidor?
Opening the humidor exchanges conditioned air with room air. The sensor can therefore react before the cigars themselves experience a significant moisture change.
Should I adjust my humidor every time the RH changes?
Usually not for small, temporary movements. Long-term stability and trends are more informative than reacting to every short-term fluctuation.
Does hygrometer placement matter?
Yes, especially in larger humidors. Airflow, humidification sources, shelves, cigar density, and cabinet design can create small differences between locations.
