Humidity refers to the amount of water vapour in the air. Relative humidity measures the water content of the air relative to the maximum amount it can hold at that temperature. At 100% relative humidity, the air is completely saturated. Humans feel most comfortable within the humidity range of 30-50%, so anything close to 100% is quite uncomfortable. Our sweat doesn’t evaporate, causing us to feel hotter. High humidity can also cause your hair to frizz because the hydrogen in water vapour bonds with the proteins in hair, making the hair swell, curl and frizz.

Key Takeaways:

• Meteorologists say that hot and humid weather are expected this week after the country has been enjoying much heavy rains and thunderstorms.
• When meteorologists talk of humidity they mean the amount of water vapor that exists in the air and although it determines whether there will be fog.
• When the humidity is said to be hundred percent that means there is total saturation of the air by water vapor and a rain is possible.

“High levels of humidity stop our sweat from being able to evaporate, and therefore we feel much hotter than we might otherwise at that temperature.”
