                                According to the USGA, a small amount of rain can reduce golf green speed by as much as 1 to 1.5 feet on a Stimpmeter. So, does water make greens faster? The scientific reality for putting greens is the exact opposite, as moisture dramatically increases friction on the surface, slowing down ball roll.
