To provide a golf ball that can prevent a decrease in carry distance of a driver shot when it rains and also, can exert excellent spinning performance upon an approach shot. The golf ball of the present invention includes a core, a cover that is provided on an outer side of the core and is provided with dimples, and an outermost layer that is formed on an outer side of the cover and made of a material having a contact angle of 90° or more. The golf ball has a dynamic friction coefficient of 0.52 or more. The material constituting the outermost layer comprises a urethane coating that contains a water repellent additive, and the water repellent additive includes a fluorinated surfactant, silicone-modified acrylate or hydrophobic silica. The urethane coating comprises a polyisocyanate as a curing agent, and the polyisocyanate includes both an adduct form and an isocyanurate form of hexamethylene diisocyanate, and a mixing ratio (isocyanurate form/adduct form) of the isocyanurate and adduct forms of the hexamethylene diisocyanate, expressed as a mass ratio, is from 95/5 to 40/60.
