Calculate the dew point temperature instantly from air temperature and relative humidity. Understand comfort levels and condensation risk. Pure client-side.
| Dew Point | Comfort Level |
|---|---|
| Dry (< 10°C) | Dry — Comfortable |
| Comfortable (10-13°C) | Comfortable |
| Slightly Humid (13-16°C) | Slightly Humid — Somewhat comfortable |
| Humid (16-18°C) | Humid — Uncomfortable |
| Very Humid (18-21°C) | Very Humid — Oppressive |
| Extreme (> 21°C) | Extreme — Dangerous condensation risk |
The dew point is the temperature to which air must be cooled to become saturated with water vapor. When the air temperature drops to the dew point, condensation occurs. It's a key indicator of comfort and moisture levels in the atmosphere.
Dew point is the temperature at which air becomes saturated with water vapor and condensation begins to form. It indicates how much moisture is in the air.
Dew point helps predict condensation, mold growth, and human comfort. Lower dew points feel drier; higher dew points feel more humid and uncomfortable.
Dew points below 13°C (55°F) generally feel comfortable. Between 13-16°C (55-60°F) feels slightly humid. Above 18°C (65°F) starts to feel oppressive.
Dew point is calculated using the Magnus formula, which relates temperature and relative humidity to the saturation vapor pressure of water.
