It can come close to 0%, but I don't believe you will ever get a 0% reading on earth, because there will always be some moisture in the atmosphere--evaporating from water bodies, soil moisture, transpiring from plants, being advected from elsewhere. The first answer states that you can get values of 0% from Santa Anas in the southwest, but actually the example values given in the answer (temperature in the 90's, -10 C dewpoint) will give a relative humidity of about 2% minimum (for 100 F, -20C dewpoint) and 6% maximum (for 90 F, -10 dewpoint). It may be possible that in certain places at certain times you would get a relative humidity that would round down to 0%, but I've looked at lots of them and have never seen anything under 1%.

0%. Happens in the southwest during Santa Ana winds. Temps in the 90s with dewpoints below -10 C.

0%, it happens when there are high temperatures and very low dew points. For example, if the temperature is 100 degrees Fahrenheit and the dewpoint is -3 degrees, the humidity would be 0%.
