Dew Point Chart in Celsius (°C)
Everything you need to read a dew point in Celsius — the comfort scale, detailed descriptions for every range, and what to expect when the dew point climbs above 16°C.
Dew Point Comfort Scale (°C)
The full comfort scale in Celsius, from dry to oppressive:
| Dew Point (°C) | Comfort Level | What It Feels Like |
|---|---|---|
| < 10 | Dry | Crisp, no noticeable humidity. Skin may feel dry. |
| 10 – 13 | Very Comfortable | Pleasant, barely noticeable moisture. |
| 13 – 16 | Comfortable | Slight moisture in the air, still fine for most people. |
| 16 – 18 | Slightly Humid | Starting to feel sticky. Hair may begin to frizz. |
| 18 – 21 | Humid | Uncomfortable for most. Sweat evaporates slowly. |
| 21 – 24 | Very Humid | Oppressive. Hard to breathe deeply. Feels tropical. |
| > 24 | Oppressive | Tropical, sweat does not evaporate. Stay indoors if you can. |
Understanding Each Dew Point Range in Celsius
Below 10°C — Dry
A dew point below 10°C means the air holds very little moisture. Common in desert climates and during winter in temperate regions. Skin may feel dry or chapped, and static electricity is more noticeable. Excellent weather for outdoor activity — no stickiness at all.
10 – 13°C — Very Comfortable
This is the range most people describe as “perfect.” Just enough moisture that your skin does not feel dry, but not enough to feel sticky. Ideal for running, hiking, or any outdoor work — common on the best days of spring and autumn across much of Europe and North America.
13 – 16°C — Comfortable (the sweet spot)
Still very pleasant. You might notice a hint of moisture in the air, but it is not uncomfortable. For most people in temperate climates this is as good as it gets — the typical dew point during late spring and early autumn.
16 – 18°C — Slightly Humid
The turning point. At 16°C most people still feel fine; by 18°C you start to notice the stickiness, especially if you are active. Hair begins to frizz. Typical of a warm summer day in much of Europe and the northern United States.
18 – 21°C — Humid
This is when most people start actively complaining about the humidity. Sweat evaporates slowly and you feel damp even standing still. Air conditioning becomes a noticeable relief. Common in Mediterranean summers and the eastern half of the United States.
21 – 24°C — Very Humid
Oppressive for most people. Sweat barely evaporates and breathing feels heavy. Outdoor exercise is genuinely risky because your body cannot cool itself efficiently. This is tropical and subtropical summer weather — without air conditioning, sleeping is very difficult.
Above 24°C — Oppressive
Tropical conditions. The air is saturated with moisture and sweat provides essentially zero cooling — it just drips off. Heat exhaustion risk is high even for healthy adults. This is a “stay inside” level, common in Southeast Asia, northern Australia, the Persian Gulf, and the US Gulf Coast during peak summer.

Frequently Asked Questions
What dew point is comfortable in Celsius?
A dew point between 10°C and 16°C is considered comfortable for most people. Below 10°C feels dry, and above 18°C begins to feel sticky and humid.
What is an uncomfortable dew point in Celsius?
A dew point above 18°C is when most people start to feel uncomfortable. At 21°C and above, the air feels oppressive — sweat does not evaporate efficiently, making it difficult to cool down.
