Estimating mugginess using relative humidity can be misleading since a high relative humidity doesn't necessarily mean high mugginess. Precipitation Plotter But since warmer air can hold more water, the relative humidity goes down to 33%.On the other hand, warm air can handle more moisture than cooler air. Hot dry skin. As relative humidity increases, the air seems warmer than it actually is because the body is less able to cool itself via evaporation of perspiration. If, for example, the outdoor temperature and dew point are both at 0 degrees (in other words, the air is saturated and can hold no additional moisture) and the temperature increases to 10 degrees but no moisture is added to the air (that is, the dew point temperature remains at 0 degrees), the relative humidity will drop to 64 percent.

The microscopic creatures can worsen allergies and asthma, so maintaining healthy humidity levels is key to minimizing them and their effects.6. Whereas in summer, humidity levels will be higher, as air can hold more water vapor at a higher temperature. Namely, we will perceive 75F temperature as: As we can see from the temperature and humidity relationship chart, 75F can feel like 70F at very low humidity levels (10% moisture levels) or 80F at very high humidity levels (100% moisture levels). Humidity levels above the recommended 50%, is when the air will start to feel dense and damp. Cooking, cleaning, dishwashing, breathing, clothes washing, showering, and other indoor processes release moisture into the indoor air, making indoor humidity levels rise. Santa Teresa Climate Data
