Why 70% Humidity Means Nothing Without the Right Temperature
Ask a cigar smoker how they store their cigars and the answer is often immediate.
"Seventy percent humidity."
It sounds precise.
Scientific.
Professional.
But here's the problem.
That number tells only half the story.
Without temperature, relative humidity is incomplete information.
A humidor at 70% relative humidity and 18°C behaves very differently from one at 70% relative humidity and 28°C.
The display shows the same number.
Your cigars do not experience the same environment.
What Relative Humidity Actually Means
Many smokers assume relative humidity tells them how much water is in the air.
It doesn't.
Relative humidity is exactly what the name suggests.
It is relative.
It compares the amount of water vapor currently in the air with the maximum amount the air could hold at that specific temperature.
Warm air can hold far more water vapor than cool air.
That single fact changes everything.
Why Temperature Changes the Meaning of 70%
Imagine two humidors.
Both display 70% RH.
One is maintained at 18°C.
The other sits at 28°C.
Although both read 70%, the warmer humidor actually contains considerably more water vapor because warm air has a much greater moisture-holding capacity.
Your hygrometer displays the same percentage.
Your cigars experience a completely different environment.
Heat Accelerates Everything
Temperature affects much more than moisture.
It changes the speed of chemical reactions.
It increases evaporation.
It accelerates oxidation.
It speeds up the movement of moisture through tobacco.
It even influences combustion once the cigar is lit.
In other words, higher temperatures don't simply make cigars warmer.
They make everything happen faster.
Moisture Is Always Moving
Tobacco constantly exchanges moisture with the surrounding air.
If the surrounding environment contains more available water vapor, the cigar gradually absorbs moisture.
If the surrounding environment contains less, it releases moisture.
This process continues until equilibrium is reached.
That equilibrium depends on both humidity and temperature.
Ignoring either one means ignoring half of the equation.
The Hidden Risk of Warm Humidors
Many cigar owners focus entirely on humidity.
Meanwhile, the humidor sits near a sunny window or inside a warm room.
The hygrometer still displays 70%.
Everything appears perfect.
But elevated temperatures can create problems.
Tobacco may absorb moisture differently.
Aging accelerates.
Essential aromatic compounds may dissipate more quickly.
The risk of mold and tobacco beetle activity also increases as temperatures climb.
A correct humidity reading cannot compensate for excessive heat.
Why Premium Storage Is Climate Control
The finest cigar storage systems do not manage humidity alone.
They manage climate.
Temperature and humidity are treated as one system.
Because they are.
This is why professional aging rooms and high-end electronic humidors monitor both values continuously.
Maintaining one while ignoring the other creates unnecessary instability.
Finding the Sweet Spot
Most premium cigar enthusiasts aim for approximately:
- Temperature: 18–21°C (64–70°F)
- Relative Humidity: 65–70%
These are not rigid rules.
Different cigars and personal preferences vary.
But keeping both variables stable is generally more important than chasing an exact humidity number.
Stability protects cigars better than constant adjustment.
The El Septimo Philosophy
Great cigars deserve great storage.
The years invested in growing, fermenting, aging, blending, and rolling premium tobacco can be compromised by poor environmental control.
Humidity preserves moisture.
Temperature preserves balance.
Together, they protect the craftsmanship built into every cigar.
The Number That Matters
The next time someone proudly says their humidor is at 70% humidity, ask one simple question.
"At what temperature?"
Because humidity is never an independent number.
It is part of a relationship.
And understanding that relationship separates storing cigars from preserving them.
The finest premium cigars are not protected by humidity alone.
They are protected by climate.

FAQ
Why isn't 70% humidity enough information?
Relative humidity depends on temperature. Two humidors showing the same RH can contain very different amounts of water vapor if their temperatures differ.
What is the ideal temperature for storing cigars?
Most premium cigars are best stored between 18°C and 21°C (64–70°F), alongside stable relative humidity.
Can high temperatures damage cigars?
Yes. Elevated temperatures can accelerate aging, increase moisture movement, encourage mold and tobacco beetles, and alter flavor development.
Should I focus more on humidity or temperature?
Neither should be managed independently. Premium cigar storage depends on maintaining both stable humidity and stable temperature together.
