Heat index temperature vs humidity
Web9 de abr. de 2024 · Sometimes, if we talk about relative humidity, it can be misleading as well. If a region has a temperature of 40° with a dew point of 40 will lead to 100% relative humidity whereas, on the other hand, a region with a temperature of 80° with a dew point of 60 will lead to having 50% humidity.
