Cos'è il punto di rugiada?
The dew point is the temperature at which air becomes saturated with water vapor and condensation starts to form. It is always less than or equal to the air temperature. Dew point is a better indicator of comfort than relative humidity alone, because it directly measures the amount of moisture in the air. This calculator uses the Magnus formula, widely used in meteorology and HVAC applications.
Formula Magnus
α = (A × T) / (B + T) + ln(RH / 100)
Td = (B × α) / (A − α)
Dove A = 17,27, B = 237,7 °C, T = temperatura (°C), RH = umidità relativa (%), Td = punto di rugiada (°C)

Livelli di comfort del punto di rugiada
| Punto di rugiada (°C) | Livello di comfort | Descrizione |
|---|---|---|
| < 10 | Asciutto | Very comfortable, dry air. |
| 10 – 16 | Comodo | Pleasant conditions. |
| 16 – 18 | Leggermente umido | Most people comfortable. |
| 18 – 21 | Umido | Some discomfort, sticky feeling. |
| 21 – 24 | Molto umido | Uncomfortable, oppressive. |
| > 24 | Estremamente umido | Dangerous, heat exhaustion risk. |
Note importanti
- Dew point is always ≤ air temperature.
- La formula di Magnus è accurata per temperature comprese tra −45 °C e 60 °C.
- Relative humidity must be between 0 % and 100 %.
- Dew point is a better comfort indicator than RH alone.
