Yes, you can check the whether with an instrument. this instrument is called a thermometer. this is how it works... when it's freezing cold it should be below 0. when it's hot it should be at least above 10 degrees. These thermometers should be kept outside so the thermometer is absolutely right or it's close to the right answer.
However, a hygrometer can be used to use relative humidity. Or it is how much water vapor is in the air.

Relative Humidity is measured with a HygrometerHumidity is the amount of water vapor in the air.On hot days, when it feels sticky, the humidity would then be high.
A psychrometer is an instrument commonly used to measure the relative humidity.
The relative humidity (RH) in a kitchen can be measured by using a humidity gauge. A maximum indoor relative humidity of 55% RH may be acceptable, but a 50% RH better is better.

Relative Humidity is actually measure the amount of moisture in the air. It depends on how much of the air has water in it. Let's say that the RH is 50%, that means 50% of the air has water in it.
