    For an ESD, you have to build up a substantial voltage difference between two points. As humidity builds up the ability to build up substantial voltage difference goes down - and from this viewpoint so does the ESD risk.

    However, the higher humidity reduces voltage build up by conducting through moist air - which in itself is a discharge.

    Always use prudent grounding when working with ESD sensitive material regardless of humidity.

    ESD is at greater risk in High humidity. You should always work on PC's in room temperature and always wear an anti static wrist strap
