Què és el punt de rosada?
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.
Fórmula Magnus
α = (A × T) / (B + T) + ln(RH / 100)
Td = (B × α) / (A − α)
On A = 17,27, B = 237,7 °C, T = temperatura (°C), HR = humitat relativa (%), Td = punt de rosada (°C)

Nivells de confort del punt de rosada
| Punt de rosada (°C) | Nivell de confort | Descripció |
|---|---|---|
| < 10 | Seca | Very comfortable, dry air. |
| 10 – 16 | Còmode | Pleasant conditions. |
| 16 – 18 | Una mica humit | Most people comfortable. |
| 18 – 21 | Humit | Some discomfort, sticky feeling. |
| 21 – 24 | Molt Humit | Uncomfortable, oppressive. |
| > 24 | Extremadament humit | Dangerous, heat exhaustion risk. |
Notes importants
- Dew point is always ≤ air temperature.
- La fórmula de Magnus és precisa per a −45 °C a 60 °C.
- Relative humidity must be between 0 % and 100 %.
- Dew point is a better comfort indicator than RH alone.
